using
the
indigenous
GSLV-4CR
on

The two antennas of the 2130-kg satellite, used to transmit and receive functions, had been successfully deployed and the satellite was put in its final three axis stabilised mode, an ISRO release said here today.
In yesterday's maneuver, the Liquid Apogee Motor (LAM) on board the satellite was fired for a duration of 196 seconds and the satellite had achieved an orbital period of 23 hours and 42 minutes.
At 0714 hrs today the satellite was put in its final three-axis stabilised mode, The East reflector (antenna) was deployed yesterday, while the West reflector was deployed today.
INSAT-4CR was presently located at 51.8 degree Eastern longitude and is expected to reach its final orbital position of 74 degree E by September 15. After reaching its final orbital position, the satellite drift would be arrested following which in-orbit testing of the payloads would be carried out.
At 74 degree E longitude, INSAT-4CR would be co-located with INSAT-3C, KALPANA-1 and EDUSAT, the release added.
