Photos (Rest-d?) GEO-IK-2 (Mousson-2, Cosmos-2470) atop Rockot/Briz-KM on February 1st, 2011
by SiberianTiger 02-01-2011, 01:13 AM



Geo-IK-2 (Mousson-2, meaning Monsoon-2) is a Russian satellite system which will consist of two identical spacecraft for geodesic measurements.

Its purpose is determination of Earth's gravity field parameters, marking up a high precision geodesic network in geocentric coordinates, measuring of lithospherical plate movements, land tides, discrepancies in Earth's rotation and tracking of positions of Earth's poles.

Both spacecraft will work at Sun-synchronous orbits. The first Geo-IK-2 will launch on February 1st, 2011 after previous postponement from 2010 due to technical problems.

The modern Geo-IK-2 series satellites inherit to old Geo-IK spacecraft which operated back in the 80's and 90's. In total number, 12 of Geo-IK satellites were launched, last of which stopped its operation at Feb 5, 1999.

Successful launch of the Geo-IK-2 will mark reviving of Russian Space Geodesy program after a long disruption.

This is a double purpose satellite carrying out both Military and Civilian missions.

Rockot rocket carrying a military satellite has launched from Plesetsk Cosmodrome
17:06 01/02/2011

MOSCOW, Feb 1 - RIA Novosti. This Tuesday, Russian Space Force have launched Rockot launch vehicle carrying a military payload, told RIA Novosti official miltary representative Alexey Zolotukhin.

"Today at 17:00 MSK Russian Space Force personnel under command of Commander of Space Force Gen-Lt Oleg Ostapenko commenced launch of Rokot LV with a MoD satellite" - informed the agency Zolotukhin.

The launch was nominal.

"At 17:02 Rockot was tracked by G.S.Titov Main Test and Space Systems Control Centre (the primary spacecraft control centre of Russian Space Force). The expected time of spacecraft separation is 18:35 MSK (15:35 UTC) within reach of Russian ground control stations."

Thumbs down

There is a problem! Ground control stations could not establish communications with the spacecraft at the expected time. NORAD is tracking an object 37363 in a 330 x 1077 orbit, which looks like an upper stage problem to me!

I wonder does it have dV (fuel/engines I mean) enough to fix its orbit with its own means?

Some "sources from rocket and space industry" say it does. Other don't support this. Howver, the satellite is classified and nobody of those who knows can tell things openly.

And there are too little facts to tell about possibilities, yet. I might not separate from the Briz, for example.

Oops, that actually was a copy-pasted piece from my previous post about Elektro-L... Removed it now.

Let me say my summary of what's caught from the white information noise surrounding this. Thus far, it's looking to me like:

1. Briz-M has performed the first post-launch burn (about 10 minutes long) and raised apogee to operating value.

2. It then initiated the second burn, circularizing the orbit (there should have been a ~150 secs long burn), but suddenly shut down shortly after it did, raising perigee only slightly. At that moment, the spacecraft separated. NORAD can see the two objects right now:

Quote:
OBJECT A, 37362, 2011-005-A:

Epoch (UTC) 2011-02-01 18:42:49
Orbit # at Epoch 3
Inclination 99.457
RA of A. Node 41.985
Eccentricity 0.0451929
Argument of Perigee 98.600
Period 1h 38m 14s (98.23 min)
Perigee x Apogee 356 x 993 km

OBJECT B, 37363, 2011-005-B:

Epoch (UTC) 2011-02-01 20:21:32
Orbit # at Epoch 3
Inclination 99.459
RA of A. Node 42.077
Eccentricity 0.0519429
Argument of Perigee 107.250
Period 1h 38m 29s (98.48 min)
Perigee x Apogee 319 x 1 053 km
3. A difference in orbits of the two pieces can be explained as result of fuel dumping activity Briz-KM performed. And if that happened, that it good, otherwise it could explode in orbit, creating another debris belt.

4. It is not clear if a contact with the satellite itself was established or not. But even if they have a contact, some people say it has only 25 kilos of hydrazine in RCS system onboard, while the delta-V cost for cirlularization from 319 x 1 053 km is about 200 m/s (didn't check that myself yet)... So it is not enough, by the figures.

I don't know if it's able to carry out its mission from a varying height orbit, I think it's not likely.

From the latest news, the Space Force has established communications with GEO-IK-2 spacecraft, which is now in an off-nominal orbit. A possibility of it carrying out the mission is under estimation.

(I've changed the status to "Partial Failure" because of this).

Glad to hear it made it into orbit -- I've been worried for a long time that the northerly sun-sync orbits that cross the center of the US during rev 0 have the seeds of a major misunderstanding in the event of launch troubles.

"Communications with the spacecraft are established. Downlinked telemetry confirms solar arrays opening. All onboard systems are running nominal." - said Interfax agency's source
A special investigation committee is being gathered to decide on usability and further actions involving Geo-IK-2 satellite owned by MoD. Expectations are, that after about a month spent in the current orbit, it drifts off the initial orbital plane orientation in Sun-bound coordinates, which may create problems for onboard electric and thermal systems that are supposedly built for constant sunlight conditions (and that's why Sun-synchronous terminator-trailing orbit had been chosen for it).

So, the Rockot and Satellite systems worked nominally, its a BrizKM engine premature shutdown ?

I hope they won't find out that someone put a wrong quantity of propellant in the BrizKM tanks...
