Title: LIVE: PSLV C38 - Cartosat-2E & 30 nanosats - June 23, 2017 (03:59 UTC)
Post by: sportyfailure on 07/09/2016 12:28 PM
My theory on EMIsat is that it is an Electromagnetic Signal Intelligence Spy satellite being developed for Indian Military

Few years ago there was a reference to a plan to design ELINT and SIGINT payloads for satellites that appeared to be under a DRDO project name called KAUTILYA. The reference appeared in the 2013-2014 annual report of drdo Ministry of Defence see Page 95 of : https://web.archive.org/web/20160304075105/http://www.mod.nic.in/writereaddata/AnnualReport2013-14-ENG.pdf (https://web.archive.org/web/20160304075105/http://www.mod.nic.in/writereaddata/AnnualReport2013-14-ENG.pdf)

ISRO will design the satellite and DRDO will design the payload.

The above info is my theory and is currently unconfirmed.

Edit: I have contacted a few Indian defence journalists by email and waiting to hear back. I hope they respond.
Is this different from the reported  Communication Centric Intelligence Satellite (CCI-Sat), whose payload was reportedly under development by DRDO? Or maybe they are the same?

CCI-Sat's relation to this project is unknown.

But they are likely to be related and also may have some common goals. One of them will SIGINT while the other one may be ELINT.

GISAT will augment them with continuous imaging support.

EMIsat seems to be an Earth observation satellite (anyone knows what this acronym means?)
SPaDEx seems to be a Space Docking Experiment between 2 mini satellites

Post by: worldtimedate on 04/07/2017 06:34 AM
It appears to me that ISAC ( ISRO Satellite Application Center ) has let ISRO down again by not having the Satellite ready for launch in due time whereas ISRO's launch vehicle team seems to almost ready with the launch, by having the launch vehicle assembled. The same thing happened to GSAT-9 launch when at the last moment ISAC announced that they haven't completed with the satellite development, testing etc. And mind you, according to a recent report, ISAC has an ambitious plan to develop 16 to 17 satellites every year from next year with the participation of Indian industry. This delay appears to further delay the launch of LVM3 which has already been pushed from Mid-January to April End and now early June. I hope, by the time, middle of June appears, ISAC would NOT say that GSAT-19E has some problems to be fixed.

PSLV C38 is also planned for next month, but the launch will happen depending on the priority and availability of the satellites, Venkitakrishnan said. "The vehicles are ready," he added.

It appears that the satellite is still awaited.

I am one of the students involved in one of the QB 50 satellites (COMPASS 2 to be precise) and right now we have no information on the current launch date from any official side, that's why I am asking...

That article is dated 11 May. The author of the article is clear that the next mission is GSLV Mk.III in May.

"Now, the team of scientists and engineers are focussed on the next mission - GSLV-MK III, boosted with fully indigenous cryogenic engine. The GSLV-Mk III will launch the communication satellite GSAT-19 in May."

However, the source is

"LPSC director S Somnath had earlier said that the GSLV-Mk III is set to launch the communication satellite GSAT-19 by May end and then Earth observation satellite Cartosat-2E will be launched via PSLV-C38 by June first week. "

It could be the author got the dates mixed up.

A part of the nanosatellites are ISL19: isilaunch19 mission patch payloads (http://blog.isilaunch.com/isilaunch19-mission-patch-payloads/)
ISL19 involves 23 cubesats:
8x LEMUR (3U)
8x QB-50 (see image, blank = 2U)
3x Diamond SSG (3U)
Aalto-1 (http://www.aalto1.fi/aalto1_in_english.html) (3U)
ROBUSTA-1B (https://en.wikipedia.org/wiki/ROBUSTA-1B) (1U)
skCUBE (https://directory.eoportal.org/web/eoportal/satellite-missions/s/skcube) (1U)
SUCHAI (http://spel.ing.uchile.cl/suchai.html) (1U)

Aalto-1, ROBUSTA-1B; SKCUBE; Suchai were originally part of ISL09 (Formosat-5 + Sherpa)

Hi,

A very warm welcome.
There has been no media reports suggesting delays due to launch vehicle or satellite.

My sources at sriharikota suggest that ISRO is simply prioritizing LVM3-D1 launch. Again this is not an official statement.

ISRO may also be waiting on some other commercial payloads other than those part of ISIL.

Primary objective:

In order to provide high resolution, this satellite will prove more specific scene spot imagery. PSLV-C38/Cartosat-2 Series Satellite mission is scheduled to be launched from ISRO's trusted workhouse - SDSC SHAR, Sriharikota, located in Andhra Pradesh.

About the mission:

* This is similar to earlier launched satellites in the series. The Cartosat-2 Series Satellite along with co-passenger satellites from abroad is planned to be launched by PSLV-C38 into the altitude of 500 km
Cartosat-2 Series has the capability of a long-track and across-track steering, up to 26 degrees

* ISRO has invested an amount of Rs. 160 Crores for this mission

* The satellite will have a single panchromatic camera along with multi-spectral cameras which can detect scene specific images

* Co-passenger satellites includes nano-satellites, one each from various countries. Using the panchromatic camera, the satellite will have a multi-spectral instrument, which will support it in adapting high-resolution land observation and cartography

* Cartosat-2 Series whose PAN camera covers 50 degrees of the payload area can steer up to 45 degrees on-track as well as across and will cover the entire earth in 1867 orbits on a 126-day cycle

* Not only capturing images, the satellite also has the ability to record videos from the sky. It will help in scanning a wide range of activities involving military and civil planning

Facts

* The satellite can produce images of up to 100 cm in resolution but in black and white specifically, compared to the 80 cm offered by Ikonos

* In the past, India used to buy in bulk images from Ikonos at about USD 20 per sq km of imagery

* With Cartosat-2 offering better resolution at 20 times lower cost per sq m of imagery, buying images from Ikonos has declined.

If the reported date (June 23) holds good, it would mark a gap of 18 days between two successive Indian launches - exactly matching the record set by GSLV-F05 (Sep-8-2016) and PSLV-C35(Sep-26-2016).

Mission brochure is out too:
http://www.isro.gov.in/pslv-c38-cartosat-2-series-satellite/pslv-c38-cartosat-2-series-satellite-brochure

With a total payload mass of 955 kg and target orbit of 505 km SSO, I'm not sure why they went for an XL configuration with those strapons. It appears well within the ability of CA variant, unless a customized payload adapter has added extra mass.

India's Polar Satellite Launch Vehicle, in its 40th flight (PSLV-C38), will launch the 712 kg Cartosat-2 series satellite for earth observation and 30 co-passenger satellites together weighing about 243 kg at lift-off into a 505 km polar Sun Synchronous Orbit (SSO). PSLV-C38 will be launched from the First Launch Pad (FLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. This will be the seventeenth flight of PSLV in 'XL' configuration (with the use of solid strap-on motors).

The co-passenger satellites comprise 29 Nano satellites from 14 countries namely, Austria, Belgium, Chile, Czech Republic, Finland, France, Germany, Italy, Japan, Latvia, Lithuania, Slovakia, United Kingdom, and United States of America as well as one Nano satellite from India. The total weight of all these satellites carried on-board PSLV-C38 is about 955 kg.

PSLV-C38 to lower its altitude after separation of Cartosat-2E to inject other satellites
PSLV-C38 upper stage to maneuver to a lower altitude after separation of satellites presumably as a test for a future mission

http://www.deccanchronicle.com/science/science/200617/isro-to-lower-rockets-altitude.html

Quote
Director, Vikram Sarabhai Space Centre, Dr Sivan said the plan was to lower the altitude of the rocket in space from 500 km to 350 km to launch the satellites in different orbits. The fourth stage will be kept active till it makes 10 orbits around the earth. Earlier, the fourth stage of the rocket that had launched 20 satellites in one go on June 22, 2016, was cut off for 16 minutes and 30 seconds after the lift-off. The 20 satellites were injected into the same orbit.

Before that, scientists had re-started the fourth-stage engine of the PSLV for four seconds after the rocket injected six Singapore satellites into the same orbit on December 16, 2015. These experiments came in handy for Isro to place eight satellites in different orbits from the fourth stage of the PSLV-C35 on September 26, 2016.

I guess I sort of misunderstood the report. The brochure indeed says the last customer satellite separates at ~510 km altitude. This maneuver post-separation of satellites is apparently meant as a test for a future mission involving a satellite that requires such a low orbit.

The list of other satellites are

Aalto 1

Horray for the first Finnish satellite. Getting the ride to orbit after the second Finnish satellite already got deployed *and* stopped working (Aalto 2 got to ISS on the Cygnus, was deployed and few weeks later ended up no longer responding to commands)

Was originally booked on Falcon 9 along with Formosat, but moved to this rocket after SpaceX delays due to certain unfortunate event that kinda wrecked the schedule last autumn.

It can also be debated whether this is the first real Finnish satellite, as the QB-50 satellites are registered to the Netherlands regardless of their country of origin. But Horray! gotta wake up early tomorrow :)

"few weeks later.." For the historical record do you happen to know when exactly Aalto 2 stopped working? I would say Aalto 2 was the first Finnish
satellite (even if it will be UN-registered by Belgium).

Good luck with Aalto-1.

According to their website, the problem arose 4 days after deployment. Not sure, when it finally stopped.

Looks like they have not declared it as a total loss yet, but if they don't hear from it soon...

Here's hoping Aalto-1 fares better even if it gets there fashionably late.

HYDERABAD: India's 'eye in the sky' is set to become sharper and wider with the launch of a third spacecraft in Cartosat-2 series -- a dedicated satellite for defence forces -- from the Sriharikota spaceport tomorrow.
Quote
The previous satellite in the series had a resolution of 0.8 metres. The latest remote sensing satellite slated to be launched on board PSLV-C38 tomorrow morning has a resolution of 0.6 metres, which means it can spot even smaller objects.

"It can recognise objects within that square (0.6 m by 0.6 m)", an ISRO official told PTI on condition of anonymity.

Once this satellite becomes operational, it would be "handed over" to the defence forces, which have their own "set up," including ground-stations and trained manpower to access data.

On the need to have a third satellite in the series, the official said, "The revisit time is the one which determines your data accessibility. More the number of satellites, the better and shorter revisit time you will have and more data you will get."

I'm not sure really. The report quotes an anonymous source, so there is a certain level of confusion with the intended use of this bird. Unlike the previous two 'Cartosat 2 Series' namesakes, this was often featured in many ISRO presentations (with a proper name as 'Cartosat-2E') indicating it was likely a civvie, while references to the former two were often avoided. But now this too got the official name as 'Cartosat 2 Series'.

It is my understanding that the Cartosat series in general have been considered 'dual-use' by the authorities considering their relatively hi-res imaging capabilities. So yeah, to my mind its really a question of whether it is a normal 'dual-use' Cartosat or a 'military-only' one as its two predecessors (or four considering that both 2A and 2B too have been rumoured to be dedicated for 'strategic users').

HYDERABAD: India's 'eye in the sky' is set to become sharper and wider with the launch of a third spacecraft in Cartosat-2 series -- a dedicated satellite for defence forces -- from the Sriharikota spaceport tomorrow.
Quote
The previous satellite in the series had a resolution of 0.8 metres. The latest remote sensing satellite slated to be launched on board PSLV-C38 tomorrow morning has a resolution of 0.6 metres, which means it can spot even smaller objects.
Quote
"It can recognise objects within that square (0.6 m by 0.6 m)", an ISRO official told PTI on condition of anonymity.
Quote
Once this satellite becomes operational, it would be "handed over" to the defence forces, which have their own "set up," including ground-stations and trained manpower to access data.
Quote
On the need to have a third satellite in the series, the official said, "The revisit time is the one which determines your data accessibility. More the number of satellites, the better and shorter revisit time you will have and more data you will get."

As it's a military satellite will its final orbital parameters be classified?
I'm not sure really. The report quotes an anonymous source, so there is a certain level of confusion with the intended use of this bird. Unlike the previous two 'Cartosat 2 Series' namesakes, this was often featured in many ISRO presentations (with a proper name as 'Cartosat-2E') indicating it was likely a civvie, while references to the former two were often avoided. But now this too got the official name as 'Cartosat 2 Series'.

Does that indicate to you that it maybe a dual use satellite by both military and civilian authorities?
It is my understanding that the Cartosat series in general have been considered 'dual-use' by the authorities considering their relatively hi-res imaging capabilities. So yeah, to my mind its really a question of whether it is a normal 'dual-use' Cartosat or a 'military-only' one as its two predecessors (or four considering that both 2A and 2B too have been rumoured to be dedicated for 'strategic users').

Do you think the obfuscation in this case is deliberate or accidental?

Its not likely to be accidental, considering that awkward name 'Cartosat 2 Series' for three satellites in a row. All other ISRO satellites have used atleast a distinct suffix as an identifier in their formal names. The fact that they had called these satellites Cartosat-2C, 2D and 2E in the beginning, but later resorted to these confusingly identical names would suggest that they might like to avoid chances of public identification of these satellites individually in the future. Or maybe there are other reasons that doesn't appear to my mind at the moment.

It can also be debated whether this is the first real Finnish satellite, as the QB-50 satellites are registered to the Netherlands regardless of their country of origin. But Horray! gotta wake up early tomorrow :)

Aalto-1 is not part of QB50.

Yep, but Aalto-2, which was launched from ISS, was.

But lets focus on the mission now.

ISRO plans PS4 maneuvers after separation of satellites (http://www.thehindu.com/sci-tech/isro-plans-complex-manoeuvres/article19127342.ece)
Quote
“Once the last satellite has been separated from the rocket at a height of 520 km, the fourth stage of the rocket (PS4) comprising two liquid propellant engines will be shut down and reignited three times,” Mr. Jayakumar told The Hindu. While the first two firings are expected to last about six seconds each, the third restart is likely to fire up to 40 seconds.

The multiple reignition of the on board engines will validate the technique and provide ISRO with the mission flexibility to inject satellites into three different orbits in a single flight to reduce the launch cost and save time.

An earlier report (http://forum.nasaspaceflight.com/index.php?topic=41762.msg1691864.msg#1691864) had also mentioned that the PS4 would be maneuvered to a lower altitude of 350 km as part of the test.

Although; that pitchover maneuver after launch was so abrupt it startled me!!

Yes. It looked quiet sharp, I am thinking, it might just be a different camera angle(?).

They really should try to make the speeches a wee bit shorter.

Some updates from the address

- SCE-200 development accelerated.
- Meanwhile the thrust of Vikas engines and CE-20 would be augmented for greater payload capability in GSLV-II  and GSLV-III.
- VSSC Director sort of hinted at some experimental payloads onboard the PS4 stage.

PSLV-C38 / Cartosat-2 Series Satellite

India's Polar Satellite Launch Vehicle, in its 40th flight (PSLV-C38), launched the 712 kg Cartosat-2 series satellite for earth observation and 30 co-passenger satellites together weighing about 243 kg at lift-off into a 505 km polar Sun Synchronous Orbit (SSO). PSLV-C38 was launched from the First Launch Pad (FLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. This is the seventeenth flight of PSLV in 'XL' configuration (with the use of solid strap-on motors).

The co-passenger satellites comprise 29 Nano satellites from 14 countries namely, Austria, Belgium, Chile, Czech Republic, Finland, France, Germany, Italy, Japan, Latvia, Lithuania, Slovakia, United Kingdom and United States of America as well as one Nano satellite from India. The total weight of all these satellites carried on-board PSLV-C38 is about 955 kg.

The 29 International customer Nano satellites were launched as part of the commercial arrangements between Antrix Corporation Limited (Antrix), a Government of India company under Department of Space (DOS) and the commercial arm of ISRO and the International customers.

Congrats to ISRO and thank you! for safe launch of many cubesats that ware waiting too long for ride on Falcon 9.

Especially happy and proud are now in Slovakia (our brothers from central Europe) and SOSA organization since their skCUBE is the 1st Slovakian satellite, home design, home made and now launched successfuly into space.

skCUBE team just confirmed strong signal acquisition, first 19 data packets received, good health, rotation stabilized to 1 deg/s. All in all total success! Gratulujem bratia Slováci !!! :)

I wonder if as these satellites gain capabilities,  that if they have military usage we will hear & see less & less about them.

Fifty-eight minutes after the rocket thundered off from the Satish Dhawan spaceport at Sriharikotta and ejected the 31 satellites into orbit, the twin engines of PS4 were first restarted. The process was repeated 46 minutes later. The third restart was scheduled about midnight after the PS4 completed nine orbits.
Quote
“With the first and second restarts, the PS4 orbit was brought down from 505 km to 350 km,” K. Sivan, Director, Vikram Sarabhai Space Centre told The Hindu from SHAR. The third reignition of the engines would involve only a change in inclination.

With its low perigee of 342 km, Object A might be PS4 perhaps?

The NASA site named the satellite name as CN06.

India CubeSat InflateSail, Object F SPC# 42770. Launched on June 23, 2017. The Sail was deployed yesterday from what we understand. This pass was imaged on July 12, 2017 @ 3:39:33 UT as it was passing through Bootes above the bright star Arcturus at a distance of 575.3 Kms @ a magnitude of around +4.2 with a phase angle of 83 degrees. This is nearing the limit for our Sony DSC w-5. We could just pick the satellite up naked eye as it approached Bootes then it brightened up real quick! We inverted the image to make the track easier to see. Exposure was 30 seconds,ISO 400. Enjoy! Regards Thomas

The word is one of the six Sprite femtosats hosted on Venta and Max Valier has separated and phoned home:

https://www.newscientist.com/article/2141956-smallest-satellite-ever-paves-way-for-planned-interstellar-fleet/

Quote
Breakthrough Starshot has taken the first step towards their grand plans to one day send spacecraft to Alpha Centauri. On June 23, the $100 million initiative to send light-propelled spacecraft to our nearest star sent the tiniest-ever satellites into orbit.

An Indian rocket carried six of these miniature satellites, called Sprites, into space. Two of them are attached to the sides of other, larger satellites: the Latvian Venta satellite and the Italian Max Valier satellite. Once communications are established, the Max Valier satellite will release the other four Sprites to orbit on their own.

Each Sprite is a four-gram square of circuit board measuring 3.5 centimetres to a side. Despite their small size, the Sprites carry a lot of instruments. Each one has a computer processor, solar panels, a magnetometer, a gyroscope, and a radio for communicating with researchers on Earth.                             

So far, researchers have only gotten a signal from one of the two Sprites hitching a ride on the larger satellites. The rest have not been released yet because the Max Valier satellite has not made contact with its mission controllers, possibly due to problems with its radio antenna. Without a functioning radio antenna, the satellite will be unable to receive any command to release its cargo.

Zac Manchester, the Harvard researcher leading the project, views even that one signal as a triumph. “We were really just trying to get them up there and communicate with them,” he says. “It’s the first time that a spacecraft on this size scale has worked.”

The world's smallest space probe, conceived at Menlo Park's visionary Breakthrough Starshot, has phoned home.
                           
The flying computer chip dubbed "Sprite," the size of a Saltine cracker, is healthy, happy and sending us signals from Earth's orbit, 400 miles from home.

It's still a long way from where its progeny may someday travel: our neighboring star system Alpha Centauri, 24 trillion miles away. The dream is for Sprite-like spacecraft to take close-up images and collect data - maybe even detect gases produced by alien life.

The little Sprite could someday help answer the big questions of life in the Universe: Are we alone? Are there habitable worlds out there? If so, can we reach them?

"But it's very good first step. It's proof of concept," said Breakthrough Starshot director Pete Worden, former director of NASA Ames Research Center, from his office on the valley's storied Sand Hill Road. "It's very exciting."

Sprite is the brainchild of Zac Manchester, whose Kickstarter "KickSat" campaign at Cornell University raised the first funds to develop the concept. This month, he joins the faculty of Stanford's Department of Aeronautics and Astronautics. His arrival at Stanford is expected to accelerate the chip satellite effort.

Sprite weighs just four grams, lighter than a quarter. It has its own solar panel, communication capabilities and sensors.

Such tiny spacecraft are possible thanks to rapid advances made in the semiconductor industry, according to Manchester. Most of the features of a traditional spacecraft can be integrated onto a chip-scale device. Sprite is built using the same devices and processes used in the consumer electronics industry.

Sprite has siblings - several Sprites were launched on June 23 - but they've gone incommunicado. They don't fly on their own; they're piggybacking on two satellites.

The one researchers hear is broadcasting a standard radio signal, charging its batteries with sunlight. News came of its signal late last month, via a Cornell ground station. (Amateurs can also listen in; Manchester's KickSat offered a design and instructions for a low-cost and portable Sprite receiving station. Consisting of a hand-held antenna, low-noise amplifier, low-cost USB radio receiver dongle, it can be built for about $200, plus a PC to run the software.)
