OverviewINSAT–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. LaunchInsat-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.
