Insat

Insat (Indian National Satellite System) was a multipurpose satellite system for telecommunications, broadcasting, meteorology and search and rescue services.

Commissioned in 1983, Insat was the largest domestic communication system in the Asia-Pacific Region, and was a joint venture of the Indian Department of Space (DOS), Department of Telecommunications, India Meteorological Department, All India Radio and Doordarshan. As of 2004 the Insat space segment consisted of: Insat-1D, last of the Insat-1 series launched in 1990; three ISRO-built satellites, Insat-2A launched in July 1992, Insat-2B launched in July 1993 and Insat-2C launched on December 7, 1995; Insat-2DT acquired from Arabsat; Insat-2E launched on April 3,1999; Insat-3B launched on March 22nd 2000; Insat-3C launched on January 24th 2002; Insat-3A launched on April 10th 2003; Insat-3E launched on September 28th 2003; and Gsat-2 and Gsat-3.

The 440 Newton Liquid Apogee Motor (LAM) took the satellite from its Geosynchronous Transfer Orbit (GTO) of 649 km perigee and 36,000 km apogee with an orbital inclination of 7 deg. The LAM was fired for a total duration of 121 minutes in three phases on September 29, September 30 and October 1. A total velocity of 1460 m/sec was added by LAM at apogee.

Gsat-3 / Edusat was the first Indian satellite built exclusively for the educational sector. It was mainly intended to meet the demand for an interactive satellite based distance education system for India. Edusat was launched into a geosynchronous transfer orbit by its launch vehicle. Edusat was to reach geostationary orbit by firing, in stages, its on board Liquid Apogee Motor (LAM). In geostationary orbit the satellite was to be co-located with Kalpana-1 and Insat-3C satellites at 74 deg East longitude.
Compared to earlier satellites in the Insat series, Edusat used several new technologies. The spacecraft was built around the I-2K standardised spacecraft bus. It had a multiple spot beam antenna with a 1.2 m reflector to direct Ku band spot beams, a dual core bent heat pipe for thermal control, high efficiency multi-junction solar cells and an improved thruster configuration for optimised propellant use for orbit and orientation maintenance. The satellite used radiatively cooled Ku-band Travelling Wave Tube Amplifiers and a dielectrically loaded C-band demultiplexer for its communication payloads. Edusat carried five Ku-band transponders providing spot beams, one Ku-band transponder providing a national beam and six Extended C-band transponders with a national coverage beam. It was to join the Insat system that already provided more than 130 transponders in C-band, Extended C-band and Ku-band for a variety of telecommunication and television services.
