INSAT-3A Launch on April 9, 2003

ISRO's multipurpose satellite, INSAT-3A, is scheduled for launch by Ariane-5 launch vehicle of Arianespace in the early hours of April 9, 2003 (as per IST), from Kourou in French Guyana.

The 2958 kg INSAT-3A is a multipurpose satellite for providing telecommunication, television broadcasting, meteorology and satellite aided search and rescue services. It carries 12 C-band, 6 upper extended C-band, 6 Ku-band and one search and rescue transponders. The meteorological instruments consist of a Very High Resolution Radiometer, a Charge Coupled Device (CCD) camera and a data relay transponder.

INSAT-2E Placed Close to Geostationary Orbit

The 440 Newton thrust Liquid Apogee Motor (LAM) on board INSAT-2E was successfully fired again this afternoon (April 8, I999) at 12.35 pm IST placing the satellite close to its final Geostationary Orbit. The LAM was fired for a duration of 33 minutes.

With this orbit raising manoeuvre operation, conducted from the Master Control Facility at Hassan, the perigee of INSAT-2E has been raised from 14,600 km to about 32,100 km. The apogee is 35,925 km. The inclination of the orbit with respect to the equator has been further brought down from 1.027 degs to 0.15 deg. The orbital period is now about 22 hours 27 minutes. INSAT-2E will henceforth remain within the radio visibility of Hassan continuously.

Further, the last firing of LAM is planned for a short duration on April 10, 1999 with which the satellite will enter into the "drift orbit" to drift slowly towards its final location of 83 deg East longitude where it will be colocated with INSAT-1D. Precise orbit determination is being carried out to determine the requirement of remaining orbit manoeuvre operations.

The 440 Newton Liquid Apogee Motor (LAM) which was used to raise the orbit of INSAT-2E from the geostastionary transfer orbit in which it was placed by Ariane on April 3, 1999 to the present near geostationary orbit has been so far fired for a total duration of 6540 sec. The LAM has shown excellent performance during all the three firings. This engine has been indigenously designed and developed by the Liquid Propulsion Systems Centre, Thiruvananthapuram.

All systems on board the satellite are functioning normally.

INSAT-2E Ready for Launch

All preparations for the launch of INSAT-2E, the last satellite in the second genaration INSAT-2 series built by ISRO, have been completed at the launch site in Kourou, French Guyana. The satellite was mated with the launch vehicle on March 29, 1999 and overall checks have been completed. A full dress rehearsal of the launch with the involvement of the launch centre at Kourou, the INSAT-Master Control Facility (MCF) at Hassan in Karnataka and the network of telemetry, trackng and command stations at Perth in Australia, Fucino in Italy and Lake Cowichan in Canada that will support the INSAT-2E launch,was held in March 30-31, 1999

The Launch Readiness Review of the 117th launch of the Araiane with INSAT-2E stellite on board, was completed yesterday (March 31, 1999). The launch is scheduled between 03.33 am and 04.23 am IST on April 3, 1999.

INSAT-2E launch will be telecast live by Doordarshan between 02.50 am and 05.00 am on then morning of April 3,1999.

INSAT-2E Orbit Raised Further

The second orbit raising operation by firing the 440 Newton thrust Liquid Apogee Motor (LAM) on board INSAT-2E, was successfully carried out this afternoon (April 6, I999) at 01.45 pm IST from INSAT Master Control Facility, Hassan. The Apogee Motor was fired for a duration of 60 minutes 05 seconds. With today's manoeuvre, the perigee of INSAT-2E orbit has been further raised from 2000 km to 14,600 km. The apogee is 35,925 km and the orbital period is about 15 hours 34 minutes.

Further, the inclination of the satellite orbit with respect to the equator has been reduced from 3.289 deg to 1.027 deg after today's manoeuvre which is as per mission requirement. It may be noted that the first firing of apogee motor had been conducted on April 4, 1999 raising the perigee of INSAT-2E from 250 km, at the time of injection into orbit by Ariane, to 2000 km. Precise orbit determination will be carried before the next orbit raising manoeuvre is performed on April 8, 1999.

The satellite's health is being continuously monitored from MCF and all systems are functioning normally.
