USSTRATCOM has catalogued 2 objectsAccording to the launch video, the achieved S/C orbit after separation was 476km x 482km x 97.6°.- Object A 38248/2012-017A from 1st elset in 460.6km x 530.4km x 97.53° (presumably the S/C)
- Object B 38249/2012-017B from 1st elset in 461.3km x 479.0km x 97.63° (presumably PSLV 4th stage)
Those TV broadcast banners that take up the bottom third of the screen really don't work with tall skinny rockets, do they? Perhaps they could compromise, filling the sides of the screen, rather than the bottom, when they're covering a rocket launch!A better view of the lower screen with flight data in this 37 minutes video

USSTRATCOM has catalogued 2 objectsWell, it appears now that Object A was PSLV 4th stage and Object B the S/C.- Object A 38248/2012-017A from 1st elset in 460.6km x 530.4km x 97.53° (presumably the S/C)
- Object B 38249/2012-017B from 1st elset in 461.3km x 479.0km x 97.63° (presumably PSLV 4th stage)
^ How can the booster be in a initial higher orbit than the s/c? where the booster engines fired again after releasing the s/c ?Good question! ;) .The higher apogee of the booster stage could be due to a collision avoidance maneuver (CAM), but I would have expected, as is the case with other launchers, the resulting apogee of the released spacecraft to be higher than that of the booster stage..

Radar Imaging Satellite (RISAT-1) successfully placed in its final orbit The Radar Imaging Satellite (RISAT-1), launched by PSLV-C19 on April 26, 2012, has now been placed in its final Polar Sun-synchronous Orbit of 536 km height.
It may be recalled that PSLV-C19 had placed RISAT-1 in a polar orbit of 470 km X 480 km. As planned, on April 27-28, 2012, the satellite propulsion system was used in four orbital maneuvers to raise height of the orbit of RISAT-1 to 536 km. The satellite is now in its final orbital configuration and in good health. In the coming days, various elements of the C-band Synthetic Aperture Radar will be tested and calibrated as a prelude to payload operations.
As compared to the optical remote sensing satellites that depend upon sunlight, the Synthetic Aperture Radar of RISAT-1 transmits its own radar pulses (at 5.35 GHz) to study the objects on Earth. This facilitatesFor RISAT-1, imaging sessions around both 6 AM and 6 PM have been chosen.- cloud penetration and
- imaging even without sunlight.
The Indian Radar Imaging Satellite (RISAT)-1
Earth observation satellite experienced a fragmentation
event on 30 September 2016 between 2:00 and
6:00 GMT due to an unknown cause. The spacecraft
(International Designator 2012-017A, U.S. Strategic
Command [USSTRATCOM] Space Surveillance
Network [SSN] catalog number 38248), operated
by the Indian Space Research Organization (ISRO),
carries a C-band microwave synthetic aperture radar.
The spacecraft had been on-orbit 4.4 years and was in a 97.6° inclination, 543 by 539 km orbit at the time of
the event.
Over 12 fragments were observed initially by
the SSN. However, as of 8 November, only one piece
(SSN 41797) had entered the catalog, having decayed
from orbit on 12 October 2016; the remainder have
decayed as well. At the current time, this event is
categorized as an anomalous separation of multiple high
area-to-mass ratio debris. Events like this are sometimes
referred to as a shedding event.
So.... RIP RISAT-1?Not yet because it LOM has not been declared. Again it is shedding event and no indication yet that critical hardware detached. I'd wait a couple of weeks until impacts of operations are made known
The US space agency Nasa has reported that India’s earth observation satellite Risat-1 had experienced a “fragmentation event” in September last year, when pieces appeared to have broken off. The report, in Nasa’s quarterly magazine Orbital Debris, said the cause was not known. An Isro official said there was some anomaly which had been rectified, and the satellite was functioning normally.
It had been in space for 4.4 years when the incident reported by Nasa occurred. The magazine said Risat-1 experienced the fragmentation event between 0200 and 0600 GMT (7.30 am and 11.30 am IST). Over 12 fragments were observed by the Space Surveillance Network of the US, it said. By November 8, only one piece, designated SSN 41797, had entered the catalog, having decayed — from orbit on October 12, 2016. The other pieces had decayed — moved away from the satellite — as well. Eventually, space debris in the near earth orbit tends to enter the earth’s atmosphere and burn up.
The magazine said the event was categorised as an “anomalous separation of multiple high area-to-mass ratio debris”. Events like this are sometimes referred to as a shedding event. Nasa’s Space Debris Programme continuously tracks 17,000 space objects and maintains record of all space debris — non-functional objects in space — as well as operational satellites.
When contacted for clarification, Isro spokesperson Deviprasad Karnik said the satellite was functioning normally. He said Isro scientists had corrected some anomaly which had nothing to do with what was reported in the Nasa magazine.
So.... RIP RISAT-1?Not yet because it LOM has not been declared. Again it is shedding event and no indication yet that critical hardware detached. I'd wait a couple of weeks until impacts of operations are made known
In GSAT-6A, there could be a power issue. A spark could have led to a short circuit. In the last three satellites — GSAT-6, RISAT and GSAT-6A — we have shifted to a higher-powered satellite bus. We saw there were similar problems in RISAT after it completed its life.
