GW_Simulations - 30/8/2007 5:47 AMIs there going to be a webcast?
isro-watch - 2/9/2007 1:20 PMthe launch has been put on hold for 50minutes...reason: not known as yet...
sammie - 2/9/2007 6:26 PMHmm that shortfall is larger then the recent shortfall of the Atlas 5, which was subsequently deemed a failure. Inded would be interesting to know what caused the shortfall

jcm - 3/9/2007 11:10 AMInterestingly, US tracking seems to indicate a rather larger shortfall than the ISRO announcement.The tracked orbit was 168 x 31786 km x 15.8 deg, not 168 x 34710 x 20.7 deg. (Compare a standard GTOorbit of 150-200 x 35800 km). This discrepancy is larger thanthe scatter in different agencies' definitions of apogee and perigee., and the inclination is completely off.The new ISRO press release quoting a 31702 km apogee AFTER the first orbit raising burn tends to support the idea that the initial announcement was overoptimistic.
The were other heartbreaking moments. There were signal drop-outs from the tracking stations at Brunei and Biak in Indonesia, and the ISRO lost track of the vehicle. This happened on and off for three and a half minutes

isro-watch - 4/9/2007 10:07 AMISRO attributes the loss to russian supplied cryoengine...only GSLV-F03 will use russian engine...all others may use indian built engines only...
lnb15k - 17/10/2007 8:09 AMI think it is yet to stay in perfect orbit as per Real time Satellite tracking website.What you all say?

lnb15k - 15/12/2007 12:06 PMAnupama gave values regarding this satellite in October. Satellite would have gone missing only after 20/10/07 if we go by this report.
The GSLV 3rd stage re-entered on February 7, 2011 at 2123UTC near the Northern border between Mozambique and Zimbabwe
is this a controlled reentry?
