INSAT-3B is an Indian communications satellite which was built by the Indian Space Research Organisation and operated by Indian National Satellite System. It's the first Geostationary satellite by India.
Overview
INSAT–3B is the first satellite built under INSAT–3 series of satellites to join INSAT system. It is based on the I-2000 satellite bus. This satellite primarily serves to business communication, mobile communication and developmental communication.it provides the first set to transponders for Swaran Jayanti Vidya Vikas Antariksh Upagraha Yojana (Vidya Vahini) for interactive training and developmental communication. It is 3 – axis body stabilized in orbit using momentum and reaction wheels, solar flaps, magnetic torquers and eight 10 N and eight 22 N reaction control thrusters.
Its propulsion system consists of 440 N Liquid Apogee Motor MON-3 (Mixed Oxides of Nitrogen) and MMH (MonoMethylHydrazine) for orbit raising.
Launch
Insat-3B was launched on the 128th flight of European launch vehicle, Ariane of Arianespace, on 21 March 2000, at 23:28 UTC from ELA-3 at Kourou in French Guiana along with its co-passenger, a broadcast satellite, AsiaStar, belonging to a US company, WorldSpace.
Payload
- 12 extended C-Band Transponders each having a bandwidth of 36 MHz with power of 15 W
- Five Ku-band Transponders providing three channels, having a bandwidth of 77/72 MHz with power of 55W
- Mobile Satellite Services (MSS) operating in C/S band frequencies
