São José dos Campos-SP, February 10, 2020
Satellite Image Amazônia-1 begins to be closed for environmental tests

The first remote sensing satellite fully developed in the country and by INPE, Amazônia-1, is in the process of closing the sides of the service module, the Multimission Platform, at the Integration and Testing Laboratory (LIT), in São José dos Campos (SP). This phase marks the transition from the satellite tests, previously performed with its open sides, to a phase that will be completely closed, with its flight model systems and subsystems inside.

After its closure, systemic tests will be carried out, which precede the first environmental tests, which include dynamic - vibration - and thermal tests, under vacuum conditions. The Amazon-1 testing campaign started in June last year, at LIT.

The satellite will be launched from the Sriharikota Launch Center (SHAR) in India by the PSLV (Polar Satellite Launch Vehicle) rocket. The launch is scheduled for September this year.

Amazonia-1 will take on board an imager similar to that of the CBERS-4 and 4A satellites, developed in partnership with China and currently in orbit, whose images are of interest to the environmental monitoring of the Amazon region, among other applications.

A completely national satellite, designed and developed in Brazil and by the National Institute for Space Research (Inpe), Amazônia-1, which is already in the final testing phase and should be launched in February next year. "This satellite is focused precisely on observing the Amazon, it has a number of interesting features and is 100% national," said the Minister of Science, Technology and Innovations, Marcos Pontes, who participated in a press conference on Tuesday (14). press.

It is the first remote sensing satellite. Amazonia-1 will expand the capacity to monitor biomes throughout the Brazilian territory. “Amazônia-1 is going to be launched together with India. I would like it to be launched here at our Alcântara Launch Center, but we still don't have the capacity to launch a satellite of this nature over there in Alcântara [MA], but we will have it soon ”, explained the minister.

The other satellites are Anand from Pixxel,  Saditsat? from Spacefix India? and the University Consortium Unitysat. The last two were announced during the C50 speech, but I had a hard time understanding what was said.

  I did not mishear :) K.Sivan talking about the involvement of the private sector in building satellites. That's what three of those four satellites are, satellites built by private sector companies.

Amazônia-1 is listed as massing 290 kg, with a destination of 778 km SSO.

However, Business Standard: Rocket places India's 42nd communications satellite CMS-01 into orbit lists Amazonia-1's mass as betweeen 600 and 700 kg.

And, the launch is stated as in February-March 2021.

Isro to launch first satellite developed entirely by Brazil's space agency

This is not the "first satellite developed entirely by Brazil's space agency". This honor goes to SCD-1, which was launched in 1993.

And there's SCD 2 as well. Unfortunately, SCD 2A was lost in the first VLS-1 failure, and SCD 3 was scrapped.
SECO confirmed. Nominal orbit insertion.

https://space.skyrocket.de/doc_sdat/scd-1.htm

The Brazilian Space Agency AEB was established in February 1994. SCD satellites were developed by the INPE space research institute under the Brazilian Space Activities Comission, Comissão Brasileira de Atividades Espaciais - COBAE. SCD1 was launched by INPE under COBAE; SCD2, also developed by INPE, was the first satellite with AEB involvement. The AEB replaced COBAE in managing the civilian space activities in Brazil. Amazonia was built by INPE. AEB is more a bureaucratic white elephant.

 Would it be accurate to say that this (Amazonia-1) is the most sophisticated satellite developed in Brazil?  ISRO/India can derive gratification in that they are a part of it!  Together with the launch carrying the first ever Indian private sector satellite,
 it makes the PSLV C-51 quite tantalising.

Yes, this is.

More from our official team:
"Amazonia-1 will be launched by ISRO's PSLV-C51 mission, on February 28, at 10:24 am, local time in India - at 1:54 am, in Brazil. A few minutes later, the satellite will be crossing the Equator heading south. Its orbital dynamics have been calculated in such a way that, until the end of its 4-year useful life, Amazonia-1 will always cross the Equator between 10:15 and 10:45 local time, wherever it is passing.This guarantees the same lighting conditions on the earth's surface, allowing for a better comparison between images acquired from the same locations throughout the year - something desirable for several remote sensing applications."

21 satellites on this launch, and the time has shifted to the left by 1 minute:

Quote
PSLV-C51, which is the 53rd mission of PSLV, will launch Amazonia-1 of Brazil as primary satellite and 20 Co-passenger satellites from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launch is tentatively scheduled at 1023 Hrs IST on February 28, 2021 subject to weather conditions.

PSLV-C51/Amazonia-1 is the first dedicated commercial mission of NewSpace India Limited (NSIL), a Government of India company under Department of Space. NSIL is undertaking this mission under a commercial arrangement with Spaceflight Inc. USA.
...
The 20 co-passenger satellites include one from ISRO (INS-2TD), four from IN-SPACe (three UNITYsats from consortium of three Indian academic institutes and One Satish Dhawan Sat from Space Kidz India) and 15 from NSIL.

Amazônia-1 launch campaign (in Portuguese) from INPE http://www.inpe.br/noticias/noticia.php?Cod_Noticia=5680

Google translation...

In the first week of February 2021, INPE's technical team concluded the exclusive activities of the Amazonia 1 satellite at the SHAR launch base, in Sriharikota, India. The phase of exclusive activities and integration with the separation system was carried out in the laboratory called SP 1 B (Satellite Preparation 1 B). From this stage, activities must be carried out in the laboratory called, SP 2 B (Satellite Preparation 2 B) and finally, in the launch tower (SP 3). In the laboratory SP 2 B, the activities of checking for tightness, filling of the fuel tank and integration with the fourth stage of the PSLV will be carried out. On February 5, 2021, Amazonia 1 was transported from SP 1B to SP 2 B. Although the distance between the two buildings is approximately 7 km, the transport took about 90 minutes. This was necessary to meet the transport requirements of Amazonia 1 and also the security protocols of the SHAR base. Amazonia 1 has already been connected to SP 2 B and has been verified to be in perfect condition to proceed with the schedule of activities. Thus, to date, all planned activities are being carried out according to the schedule and successfully concluded and Amazonia 1 is on its way towards launching on February 28, 2021.

As Conexion Espacial has also figured out:

SAI-1 NanoConnect-2 is a 2U cubesat from UNAM (Mexico City) in collaboration with Space AI  (Mexico City and San Francisco).
The Space AI (SAI) bit is a software-defined-radio processor chip. The satellite was built in Mexico. It will be deployed
by a Maverick Inc. Mercury-3 cubesat dispenser, and (the US-based) Maverick is handling the launch booking with ISRO, which
is why the ISRO press kit thinks of it as a US customer.  Mass is 2.275 kg.

No. It is still available as a launch option and are flying the three other variants to allow more rideshares as their is high global demand.

Live coverage has begun.
DD and the Brazilian CTI ministry casts are describing the launch via previously recorded material, etc.

The lady in the announcer's booth on the DD cast providing the English language coverage--is she new? :)

Now counting through the T-10 minute mark.

Sorry--internet throughput on this Friday night is particularly poor for me.

We've progressed through a successful lift-off, staging from first to second, and second to third, followed by the third stage coast.  All well.

Now the fourth stage has ignited.

Many pad upgrades since the last launch most notable is the new Mobile Launch Pedestal replacing the Fixed Launch Pedestal and the preparation for its rail system.

New link for secondary satellites releases:


Coverage begins during satellite separations--after those of Sindhu Netra and SDSAT, and before NanoConnect-2.

Twelve SpaceBee satellites are released next.  UNITYSat is the final release.

From mission control display, spacecraft separations timeline:
PS4 Restart-1     3670.8 seconds
PS4 Shutoff-1     3678.9
PS4 Restart-2     6591.3
PS4 Shutoff-2     6598.8
Sindhu Netra      6690.7
SDSAT               6698.1
NanoConnect-2   6757.0
SpaceBee(s)       6865.9
UNITYSat           6907.9

Post-mission speeches: First up, Dr. K Sivan.
He mentions "something like 14 missions this year."  "Seven launch vehicle missions."  "Six satellite missions."  And the first unmanned Gaganyaan mission.

 Congrats to ISRO on another successful mission. A puzzling issue, is the absence of any mention of specific upcoming launches like the SSLV and the GSLV/GSAT-1. Instead, some general info about a busy schedule, including the first unmanned flight by year-end.  Nothing like "See you back here in 2 or 3 weeks for the first SSLV launch".  One was expecting that!

I'm so happy with that launch. ;D

And that was a REALLY fast lift-off!!! Cleared the tower faster than a blink.
Everything is fail-proof until it fails.

i have some issues with main satellite separation video...

it appears to be drifting sideways as opposed to smooth "push" forward

ISRO engineers seem unaffected by it even declaring it total success within few minutes of separation- so i guess its a non-issue

Maybe they are trying the Starlink "pushers, who needs them" payload separation style. ;)

Nice launch, BTW! That thing had insane thrust to weight ratio at lift-off.  :o

Many pad upgrades since the last launch most notable is the new Mobile Launch Pedestal replacing the Fixed Launch Pedestal and the preparation for its rail system.

 Did a search on ISRO and 'mobile launch pedestal', it looks like the MLP was used several years ago. It was certainly in use for the launch of GSAT 6A in March 2018.  There are hints that it was there even before that. Maybe this is a new one or modified one?

GSAT 6A was launched from the second launch pad, which already has a mobile launch pedestal. The first launch pad earlier had a fixed launch pedestal and a mobile service tower. It looks like it had been renovated for mobile launch pedestal and rail.

the MLP's for FLP are fully rectangular whereas the GSLV-2/PSLV MLP's for SLP and future TLP are rectangular with an exaggerated X to the corners.

Thanks! Indulging a bit here :D, it is a sign of India's depth that two separate, totally unconnected builders/prime contractors, are behind the respective MLPs for the FLP and SLP. For the GSLV, the developer is a public sector enterprise that is not all that well known. For the PSLV, it is a company that even the vast majority of educated Indians would never have heard of.

Unlike ths US, contracting works very differently in India especially in the Space and Defence sectors. The core expertise in Engineering is with ISRO/DRDO etc. who develop the entire detailed designs and drawings and only engage the contractors for fabrication and erection. Both MLP and SLP are ISRO in-house designs which were erected by diffrent companies like NCC, Tata Consulting Engineers, L&T etc. Private companies in this sector don't want to take up the design risk and neither does ISRO/DRDO wan't to farm out critical projects to inexperienced and/or overenthusiastic companies. This culture developed in an era were private industry didn't have a culture of working with high tech industry. Although currently this culture is changing as ISRO/DRDO etc. are becoming more comfortable with farming out design contracts too.

Both ISRO and DRDO are very vertically integrated and do most things themselves.
