Ground controllers of the Indian Space Research Organisation raised the elliptical orbit of the GSAT-14 again on Tuesday to make it more circular.

They sent out commands from the Master Control Facility at Hassan, Karnataka, to the satellite’s propulsion system or Liquid Apogee Motor (LAM). The LAM engine crackled for 44 minutes, raising the orbit to a perigee of 32,160 km and an apogee of 35,745 km. The inclination achieved was 0.6 degree. When it was first fired on Monday, the LAM helped the 1,982-kg satellite realise an orbit of 8,966 km (perigee) by 35,744 km (apogee).

M. Nageswara Rao, Project Director, GSAT-14, said that during the third orbit-raising manoeuvre scheduled for January 9, the LAM would be fired for 193 seconds. If successful, the operation would take the satellite to a much more circular orbit with a perigee of 35,564 km and an apogee of 35,741 km. The inclination will be 0.25 degree.

Then “the satellite will slow down and move towards its final orbit. It is expected to reach the final circular orbit with an inclination of 74 degrees east on January 20. We will declare it usable by January 27.”

The satellite, launched by the GSLV-D5 on January 5, was in good health, Mr. Rao said. Its final, circular geo-stationary orbit would be at a height of 36,000 km.

GSAT-14 gets closer to final slot

By Special Correspondent Communications satellite GSAT-14 underwent the third and final orbit raising operation on Thursday morning, ISRO said.

After firing its onboard motor for nearly three minutes, its controllers at the ISRO Master Control Facility at Hassan unfurled its east and west antennas, meant for two-way communication, at 9.18 a.m. and 11.30 a.m. respectively.

The spacecraft now moved in a near-circular 35,462 km x 35, 741 km orbit with an inclination of 0.25 degrees. Over the coming days it would be allowed to gradually drift until it reached its final slot over 74 degrees E longitude. The other instruments would be switched on and tested before declaring the satellite operational, the spokesman said.

Update:

Mission Status: GSLV-D5/ GSAT-14 mission:


All orbit raising maneuvers for GSAT-14 satellite have been successfully completed. Both the reflectors of the satellite have been deployed. Satellite has been put under the three axes stabilized mode.

The satellite is slowly being drifted to its designated orbital slot of 74 deg E. It will reach there on January 18, 2014 ...

Is there any dth who's going to use this satellite.

Btw good update kem siva brother.

Thanks God, this time everything is fine & ok.:sp

yes, everything is fine just because Isro offered puja to Tirupati Balaji before launch. This is regular practice world over....;)
