Ukrainian-Russian team continues Angosat preparations

By the end of April 2017, Ukrainian engineers were to begin work on the routine servicing of the Zenit rocket intended for the Angosat mission in Baikonur. At the same time, Russian and Ukrainian officials finally reached an agreement on technical cooperation in planning the launch of Angosat-1 in September of the same year. By that time, KB Yuzhnoe finalized the flight scenario, which would enable Moscow-based NPTs AP development center to model it on its simulation facility two or three months prior to launch and then program it into the flight control system of the Zenit rocket and its Fregat-SB upper stage.

Despite good progress on the engineering front of the Angosat-1 mission, political problems continued hampering the preparations of the Russian-Ukrainian launch. As of the end of June 2017, the planned liftoff for Angosat-1 slipped to October 21, however, even that date was considered optimistic within the industry. At the time, the Ukrainian team, which had to perform a scheduled maintenance on the Zenit rocket, was still waiting for permission to travel to Baikonur from the Ukrainian authorities.

Have the Ukrainian technical team members since been allowed to travel to Baikonur and begin their work?

Not heard back on that form the people I contacted, but the sat is almost ready for its final acceptance certification and pre-shipment review and in May the Fregat-SB Upper Stages for both Lybid and Angosat flights were placed in their shipping containers and are awaiting shipment to their respective MIK processing cells at Cosmodrome Baikonur. Both flights are to launch nearly back to back by the end of the year.

Angosat completes vacuum testing

On Aug. 10, 2017, RKK Energia announced that thermal and vacuum testing of the Angosat satellite inside the the VK600/300 facility at NITs RKP center in Peresvet had been successfully completed. According to the company, all modes of operation for the satellite's service systems and communications payload were tested, including various contingencies. Representatives from Angola oversaw the operations. The test chamber simulated deep vacuum, solar radiation and reflected radiation of the Earth, as well as changing position of the satellite in space, RKK Energia said.

Upon completion of tests, the spacecraft was delivered back to RKK Energia's campus in Korolev in preparation for final acceptance tests.

Only in March 2017, there were first signs that the Lybid program might have a chance to get off the ground. In an interview with the Interfax-Ukraine news agency, Acting Head of Ukrainian Space Agency, GKAU, Yuri Radchenko said that before the end of that month, the Yuzhmash factory in Dnepr, Ukraine, was expected to pay Moscow-based NPO Energomash for the RD-171M engine to be installed on the fully assembled first stage of the Zenit rocket slated to launch Lybid. At the same time, industry sources said that personnel at Yuzhmash had began testing a fully assembled second stage of the Zenit for the Lybid mission.

Thanks, RH117!

Since my previous post in this thread, I found this posting from 2.5 years ago, which gives some historical context:
<snip>
http://izvestia.ru/news/582498
<snip>

The article says two Zenit rockets are ready and have been delivered to Russia. One wil launch Elektro-L nr. 2 in June and the other is supposed to launch Spektr-RG in 2017. A TsENKI official told Izvestiya there should be no problem with the Elektro launch this June, but the Spektr-RG launch by Zenit is in jeapordy because of the uncertainty over the fate of Yuzhmash  (by 2017 Yuzhmash specialists may no longer be available to take part in launch preparations and no spare parts may be available for the rocket).

Another Zenit rocket has been assembled at Yuzhmash for the launch of the Ukrainian Lybid communications satellite, but Yuzhmash cannot afford to buy the Russian-built RD-171 engine and guidance and control systems for the rocket.

<snip>

Putting this all together, it looks like three Zenit launches are still on the manifest :
- June 2015 : Elektro-L nr. 2  (rocket ready and delivered)  (My EDIT: launched December 2015)
- ? 2015 : Lybid  (rocket still lacks engines and guidance & control systems)
- ? 2017 : Spektr-RG (rocket ready and delivered)  (My EDIT: re-purposed for Angosat-1)

<snip>


And the Spektr-RG thread from last year, regarding the launch vehicle disposition:
According to news report, Spektr has moved to Proton and the Zenit will be used for Angosat-1

this http://izvestia.ru/news/644111

http://tass.ru/kosmos/3909740

The deputy director of the Institute of Space Research Mikhail Pavlinskiy says the launch of Spektr-RG is now scheduled for March 2018. It will most likely be launched by a Proton/Blok-DM03 originally earmarked for the Glonass program. The Zenit originally scheduled to launch Spektr-RG will now launch AngoSat.

Maybe, but check and see if their is an old thread first. Might want to wait until the Lybid ships because then we know that its going to launch.

By the end of August, KB Yuzhnoe received all the necessary permissions from the government in Kiev to participate in the Angosat project. The company immediately made plans to send a team of its specialists to Baikonur to service the Zenit launcher for the mission and keep the necessary personnel at the launch site to support the Angosat campaign. As of the end of August, the launch of Angosat was set for Dec. 7, 2017, with December 14 as a backup.

The launch of the Angolan communications satellite Angosat-1 with the help of the Russian-Ukrainian Zenit launch vehicle may be postponed for the next year. The start was planned for December 7, but there were difficulties with refueling the Fregat upper stage, which should deliver the spacecraft into orbit. One of the units went out of operation - it needs to be replaced. Contractors for the launch of the satellite - the Rocket and Space Corporation (RSC) Energia - promise to repair the malfunction as soon as possible.

As Izvestiya was told in the RKK that produced the Angolan satellite, a technical malfunction was revealed in the Fregat overclocking unit (RB).

- During the training, specialists from Roskosmos revealed the abnormal operation of one of the nodes of the Republic of Belarus, said RKK CEO Vladimir Solntsev. "We are glad that we managed to localize the problem here on Earth, and save the payload over which we worked long and hard. I am sure that the malfunction will be eliminated in the shortest possible time - both the rocket and the apparatus will fly.

As Izvestia explained to the source at the Baikonur Cosmodrome, it turned out that filling up the tanks of the Republic of Belarus with one of the fuel components is not carried out. Most likely, you will have to change one of the unit's units. At the cosmodrome, this can not be done, so the "distiller" will have to return to the Moscow region of Khimki at the manufacturing plant - NPO Lavochkin.

In this case, work on troubleshooting, explained the interlocutor of "Izvestia", postpone the launch at the end of 2017 - early 2018. Instead of the selected upper stage, a similar one stored in the Lavochkin NGO can be used to launch another satellite. In this case, the delivery time of the second "Frigate-SB" to Baikonur and the need to conduct prelaunch work with it also transfer the start date to several weeks.

The source explained that on Friday and throughout the weekend at the enterprises of the industry, meetings were held to find measures for troubleshooting.

The work is continuing to prepare for launching the spacecraft "Angosat" from the space center "Baikonur", manufactured in RSC Energia (included in the GC "ROSKOSMOS), commissioned by the Ministry of Telecommunications and Information Technology of the Republic of Angola. The spacecraft is intended to provide communication and television broadcasting in the territory of the Republic of Angola, as well as the entire African continent.

The work is carried out by specialists of the Energia Corporation and other co-executing companies.

Checking the lithium-ion batteries of the spacecraft after transportation is completed, the final operations with the Zenit-2 carrier rocket after electrical checks were carried out. In addition, the transit electric circuits were tested. Work has also been done on the Fregat-SB overclocking unit to eliminate inconsistencies in the fuel line.

The launch of the spacecraft "Angosat" is scheduled for December 26, 2017.

UPDATE: Russian Launch Schedule: Change: The following flight has been cleared to proceed as originally scheduled because the Fregat guidance failure mode can only repeat itself when launched from Vostochny.

2017:
December 26 - AngoSat - Zenit-3SLBF/Fregat-SB (xxx/2006) - Baikonur, LC45/1 (or Early 2018)

New details emerge on the Soyuz failure

The complex failure scenario of the second Soyuz rocket launch from Vostochny continued emerging in the days following the accident. Although the culprit had quickly been pinned down by flight control specialists, even seasoned space engineers, who were not directly involved in the intricacies of guidance systems, struggled to fully comprehend the bizarre nature of the accident.

In the Soyuz/Fregat launch vehicle, the first three booster stages of the rocket and the Fregat upper stage have their two separate guidance systems controlled by their own gyroscopic platforms. The guidance reference axis used by the gyroscopes on the Soyuz and on the Fregat had a 10-degree difference. The geographical azimuth of previous Soyuz/Fregat launcher from Baikonur, Plesetsk and Kourou normally laid within a range from positive 140 to negative 140 degrees. To bring the gyroscopic guidance system into operational readiness, its main platform has to be rotated into a zero-degree position via a shortest possible route. The azimuth of the ill-fated Vostochny launch was 174 degrees, and with an additional 10 degrees for the Fregat's reference axis, it meant that its gyro platform had to turn 184 degrees in order to reach the required "zero" position.

In the Soyuz rocket, the gyro platform normally rotated from 174 degrees back to a zero position, providing the correct guidance. However on the Fregat, the shortest path for its platform to a zero-degree position was to increase its angle from 184 to 360 degrees. Essentially, the platform came to the same position, but this is not how the software in the main flight control computer on the Fregat interpreted the situation. Instead, the computer decided that the spacecraft had been 360 degrees off target and dutifully commanded its thrusters to fire to turn it around to the required zero-degree position. After a roughly 60-degree turn, the gyroscope system on the Fregat stalled, essentially leaving the vehicle without any ability to orient itself in space.

Roscosmos reported as recently as December 12 that this launch is not affected by the Fregat failure last month.

BTW, does anyone have the launch time for this one on December 26? Also, does S7's Space Transportation subsidiary have a dedicated website (since it looks like the Sea Launch one is already dead)?

I have not been able to locate their website. May be it will launch in the new year or there may never be one.

S7 Space does have a website. After Angosat flight by year end, Lybid should follow in 2018 from Baikonur. And then they are supposed to restart launches from Sea launch (odyssey platform) but they have no customers yet.

It is actually a Zenit-2SB80 which equals Zenit-3F. This is in part done so that it fits on the launchers first stage as the text is put on at the factory in Ukraine.

Angosat1's control and mission centre is located in the municipality of Funda, in the northern area of Luanda Province.
With 1,500 kilograms and 262.4 kilograms payload, Angosat was built in Russia, with a span of 15 years.
 The Satellite will have a primary control and mission center in Angola and a secondary center in Russia.

The estimated time booster separation occurred with a companion from the second stage of the carrier rocket. Branch "Angosat" SPACECRAFT is planned in 06:54 December 27 IIC.

KA "Angosat" created in RSC Energia commissioned by the Ministry of telecommunications and information technologies of the Republic of Angola on the basis of the service platform, consisting of a Russian-made components.

In KA "Angosat" was applied to a number of innovative solutions that enable powerful enough with relatively small (1647 kg) weight for this class. Jelektroraketnaja Ka bipropellant "Angosat" allows for prolonged dovyvedenie spacecraft on orbit (if necessary) and correction of its orbital position.

"Angosat"-a spacecraft designed to provide broadcasting on the frequency, the C-and Ku-bands to the territory of the Republic of Angola, as well as to the territory of the entire African continent. The project "Angosat" envisages the creation of a communications satellite to relay, run it on the geostationary orbit and the establishment of a terrestrial telecommunications infrastructure and broadcast television. The project also involved the Enterprise Corporation Roskosmos."

Congratulations to the entire launch campaign team, on the occasion of the final orbital launch of 2017!  I thought we'd seen the last flight of Zenit when it launched Elektro-L #2 back in 2015.  Glad to see this LV in action again.

And thank you to the launch thread/article coverage team!  I count more than 10 contributors!

EDIT 12/27: Sorry to read about the apparent loss of Angosat-1.

The information in the upper link is quite worrisome. The source says that the satellite will be declared "unworking" if it's not able to deploy its solar panels and reboot the on-board computer.

So if the quoted source is right, then the communication was lost before the solar panel deployment.

Congrats to the makers of the Zenit rocket on returning the launch vehicle to flight.

On the other hand, it's a shame that AngoSat 1 had its own problems after deployment.

Ladies and gentlemen... Rogozin:


http://www.interfax.ru/russia/593698

Anomalous space launches are the result of systematic errors in the management of Roskosmos, said Deputy Prime Minister Dmitry Rogozin in an interview with Russia-24.

According to him, the average number of employees under the age of 35 in Rosatom and the defense industry is 30%. "In Roskosmos this figure is somewhere around 18.5%," he said. "Rejuvenation of the staff is very difficult," Rogozin said.

Angosat-1 remains in orbit
Luanda - The Angolan State Secretary for Information Technology, Manuel Homem said after participating in the Council of Ministers meeting that Angosat-1 satellite has made its normal trajectory and is in orbit for which it was planned ... we have the satellite under control.
Further information will be provided “in the next eight or 16 hours on its state, readiness" – he said.
On Wednesday midmorning and without citing any official source, national and foreign media outlets reported the loss of contact with Angosat.
On Tuesday, the Zenit rocket with the first Angolan satellite on board, Angosat-1, was launched by Russia from the Baikonur cosmodrome, after having been tested numerous times.
According to Roscosmos, Russia's State Space Activities Corporation, the rocket put the satellite into orbit as planned, separating it from the orbital transfer stage.

Perhaps insurance is in case of a launch anomaly, but a spacecraft failure would be covered by the manufacturer?

And of course there will be the issue of finger pointing with the satellite manufacturer blaming the failure on the launch vehicle even after a clean launch and separation.

According to Interfax (http://www.interfax.ru/russia/593746) the reason for the failure is a short circuit.

The latest article, just published on RIA Novosti (https://ria.ru/space/20171228/1511864755.html), also confirms that so far attempts to contact the satellite have been unsuccessful.

If the solar generator has not deployed the lifetime of the satellite is directly linked to the capacity of its batteries..

The satellite successfully navigated in space, opened solar panels and antennas, began transmitting telemetric information to Earth. Communication with the spacecraft lasted 42 minutes, after which it suddenly broke off.

- Experts are trying to restore the device. Our employees study the previously received telemetric information, make attempts to get in touch, - RSC Energia told Izvestia .

The battery charge on the satellite should be enough for 10-16 hours of uninterrupted operation after separation from Fregat  (5:54 Moscow time on December 27). But RSC Energia is sure that the opportunity to establish communication will continue after this period, as the solar panels managed to open up.

After communication with AngoSat-1 satellite, created in Russia for Angola, was interrupted, experts of both countries are trying to establish the causes of the accident.

About this "Izvestia" was told by RSC Energia.

"A commission was created to investigate and parry an abnormal situation that arose on December 27 when the AngoSat-1 spacecraft was launched. This is a joint commission of RSC Energia and the Angolan side, "the corporation said.

So far, there is hope of restoring communication, as the satellite has deployed solar panels and can receive energy.

Recall that the connection with the satellite was interrupted at the 42nd minute, after the launch on December 26 from the Baikonur cosmodrome.

Communications restored!

During most of the day on December 28, the efforts to contact Angosat-1 continued and in the evening Moscow Time, the official TASS news agency reported that flight controllers had receieved telemetry from the spacecraft. This fact was also confirmed by the Angolan government.

Sequence of Angosat-1 activation after the separation from Fregat:

1. Separation contact - 30 seconds;
2. Establishment of TCR radio link - 4.5 minutes;
3. Unpinning ARDM - 30 seconds;

Even if the satellite and mission are snatched from the jaws of defeat, discharged batteries are very worrisome.

So, what could be happened is that, before the solar panels became effective, the batteries discharged, hence the loss of telemetry?

Yes, the batteries should not discharge before the solar panels begin generating effective power.  It appears that this progression failed in this instance.

Quote
The satellite successfully navigated in space, opened solar panels and antennas, began transmitting telemetric information to Earth. Communication with the spacecraft lasted 42 minutes, after which it suddenly broke off.

- Experts are trying to restore the device. Our employees study the previously received telemetric information, make attempts to get in touch, - RSC Energia told Izvestia .

The battery charge on the satellite should be enough for 10-16 hours of uninterrupted operation after separation from Fregat  (5:54 Moscow time on December 27). But RSC Energia is sure that the opportunity to establish communication will continue after this period, as the solar panels managed to open up.

Thinking ahead:
I hope the batteries are not permanently failed--they'll need them when the Earth's shadow falls on the geosynchronous orbits for several days centered on the two equinox dates/year, and GEO satellites draw electricity from their batteries.

no the SC batteries are powering the spacecraft from before the moment of liftoff to end of life of the spacecraft. The batteries may have run low on charge to the point that safe mode was triggered thus comm was not possible. All information states the spacecraft is nominally functioning at this time and their in no longer a problem. The problem is that all of these news sites are publishing many hours old information after seeing it on State media.

TASS quoted industry sources as saying that the communications could had initially been disrupted due to draining of the spacecraft's batteries, but, fortunately, Angosat-1 had already deployed its solar panels, which allowed to restore the power supply.

I should have expanded the above quote, dated December 28, 15:49 UTC:
"According to preliminary data, connection with Angosat disappeared due to discharged batteries, but at that time the satellite was already oriented to the Sun and had opened the solar panels, which gradually restored the charge in the electrical system of the device"

Angosat-1 re-establishes communication
Luanda - The Angolan satellite, Angosat-1, last Friday re-established communication with the earth station, hours after it lost contact following its launch into orbit last Tuesday evening, in Kazakhstan, in the ambit of a project developed by a Russian company.
The re-establishment of the communication with Angola’s first satellite was confirmed to ANGOP last Thursday, over the phone, by the secretary of State for Telecommunications and Information Technologies, Manuel Homem.
The launching of the Angosat-1 stimulated a wave of speculative comments in Angola and abroad, after it was announced that the earth station lost the communication signal with the satellite after it entered into orbit.

What about occasions when the solar panels aren’t able to recharge the batteries, and if the batteries aren’t able to hold a charge? Or do they mean that it was a one off incident of being launched with flat or almost flat batteries?

i'm not so sure about power supply system failture. According to quite reliable rumours, they was receiving some corrupted data from the spacecraft between official 'loss of signal' and 'connection restored' statements. According to not so reliable rumour, it was a software mishap.

Devido ao processo de vaporização de gases, vacumização e uma certa inação do computador de bordo, o satélite por algumas hora deixou de enviar telemetria.
No entanto, as 15h00 de Angola do dia 28, foi restabelecido a telemetria com o Angosat.
Actualmente decorre a normalização dos seus sistemas e subsistemas e o processo de inserção em órbita. O estado do satélite é considerado óptimo.

Bing Portuguese translation:

"Due to the process of vaporization of gases, vacumização and a certain inaction of the onboard computer, the satellite for a few hours stopped sending telemetry. However, at the 15th of Angola on the 28th, telemetry was reinstated with Angosat. At present the standardization of its systems and subsystems and the insertion process in orbit. Satellite status is considered optimal."

Hmmmm.  "Vaporization of gases".  Maybe off-gassing from the satellite confused a guidance system star-tracker, causing the satellite to go into some type of safe mode?  Just a guess, and probably wrong.

I must say that the thought that a satellite's inertial platform either doesn't notice or doesn't initially take action when some factor makes the spacecraft drift off its proper attitude makes me wince.

Moscow. December 30th. INTERFAX.RU - The problems that arose after the launch of the Angolan communications satellite Angosat were related to the compatibility of Russian and French onboard equipment standards, an informed source told Interfax.
[...] After [Angosat] launch, problems arose due to "inconsistencies" between Russian and French regulations, "the source said.
He clarified that the satellite has components produced in France, whose compatibility with the Russian standards has created difficulties.
"The problem was solved remotely by a group of young Energia employees, who developed the spacecraft," the source said.

Source: Angosat satellite ultimately ceased to function

I'd like to note, that I'm not sure how credible this info. The source makes strange (doubtful) statements:

1. The solar panels did not deploy
2. The communication with satellite reestablished on Dec 28 lasted only 15 minutes.

With respect to this info - couple questions:
Is it possible to tell if a satellite in GEO dead or alive - just by observation? Say, by registering its drift?

Also - is there any rule which require GEO-satellite operator report lost control of satellite ?

RSC Energia: work with the satellite "Angosat" will resume in April01/15/2018
The spacecraft (spacecraft) "Angosat", created in RSC Energia, commissioned by the Ministry of Telecommunications and Information Technologies of the Republic of Angola, is undergoing scheduled flight tests.

The telemetry received from the satellite made it possible to identify the problem in the operation of the equipment of the electric power supply system of the "Angosat" spacecraft. RSC Energia specialists complete the processing of available telemetry information and are preparing to conduct a series of tests.

In the near future, the spacecraft "Angosat", moving along the geostationary orbit in the western direction, will leave the radio visibility zone of the means of the Flight Control Center (Korolev).

In view of the high responsibility of maneuvers in the geostationary orbit, it was decided not to actively influence the spacecraft before it returned to the radio visibility zone.

The resumption of work related to the flight tests of the spacecraft "Angosat" is planned in mid-April 2018.

So they will try to revive the spacecraft after ~90 days with no telemetry and no command capability? No one in their right mind would voluntarily do that. It is just too embarrassing for Energia to admit that a spacecraft designed to work for 15 years only lasted 15 minutes. By April they hope everyone will have forgotten about it.

Doesn't this uncontrolled drift in the Clarke belt make Angosat a potential hazard to the other geosynchronous satellites?  (For that matter, isn't the same true for this launch's Fregat upper stage?)

Not for now: it is 177-329 km above any operational GEO sat: http://spaceflight101.com/angosat-troubleshooting-to-resume-in-april/ Fregat moved to a graveyard orbit but has a perigee entering the GEO protected zone (although not approaching any operational sats for now).

They are quoted as having isolated the problem and developed a testing campaign to try to fully recover it. Whether that's true or just a ruse to prolong the status-quo and reduce the falldown, I don't know - but it makes sense to wait out instead of rushing in the week that's left before it leaves ground station coverage with a quick untried procedure that may worsen the state of affairs (deeper failure, attitude control loss, or even an orbital change that brings it into the operational belt).

Angosat-1 is part of a recent trend for Russian design bureaus to use their own tracking stations on their own property. This started at NPO PM in Krasnoyarsk, but Energia now has two tracking dishes at the NW corner of their plant. This probably means that even other Russian stations (like the old NIP network run by the Rocket Force) can't communicate with this spacecraft.

I guess this depends on if it’s threatening other satellites by circling the geo belt and if other sats need to move out it’s way.

to clarify Airbus DS is responsible in full only for the broadcast payload. Command and Control hardware is a hybrid solution involving both Russian and European hardware and software.

Why would another comsat operator or builder help a cut-rate competitor recover from an embarrassing fiasco??

Three possible reasons:
One
Airbus Defence and Space provided the payload on the Energia s/c bus, yes?  Airbus has an interest in ensuring their payload operates, even if they've already been paid.

Two
$$$--fees for use of facilities, etc.

Aha!

And that interface, by inference from the news quoted up-thread, would be where the hardware or software incompatibilities would lie?

yes because the broadcast payload has not been activated rather only the antennas have been deployed to make the Spacecraft 3D stabilized.

Known contractors in the Angosat project:
RKK Energia/ZAO ZEM - Prime contractor and system integrator
Airbus Defense and Space - Transponder payload
AO NII Argon
FGUP NII of Command Instruments - Reaction wheels for the flight control system
AO AVEKS - Power supply system
PAO Saturn - SCCS Command and Control
ZAO TsSKT
OOO NPO Rubikon-Innovatsiya
AO NPP Geophysika-Kosmos
OOO NPP TAIS
OOO S7 Space Systems
FGUP TsNIIMash

Angosat-1 frequencies:
Beacon frequencies:
C-band - 3830 MHz
Ku-band - 10951 MHz

SCCS frequency:
Command receivers - 5741.525 and 5745.495 MHz
Telemetric transmitters - 3401.125 and 3404.125 MHz

EIRP of SCCS:
0 dBW (omnidirect. mode)
4.3 dBW (via PL antennas)

I suppose RSC Energia paying for the use of a Western Hemisphere tracking station to continue attempting communication with the satellite is out of the question?

1. They are not used to do so. I doubt they even considered changing the habits/policy this time
2. Who wants bad news before the upcoming elections in March?
3. Eclipse season is soon anyway.

The s/c is put into safe mode and hopefully comes back still powered.
