Satellite: Insat 4B

INSAT-4B is the second satellite in the INSAT-4 series. Weighing 3025 kg at lift-off, INSAT-4B is designed to augment the communication services in C-band and Ku-band. It carries 24 transponders, 12 each in C-band and Ku-band.

INSAT-4B is launched into Geosynchronous Transfer Orbit (GTO) by Ariane-5 launch vehicle. The satellite is subsequently maneuvered to 36,000 km high Geosynchronous Orbit (GSO) by using the Liquid Apogee Motor (LAM) on board the satellite. In GSO, INSAT-4B will be co-located with INSAT 3A satellite at 93.5 deg E longitude. INSAT-4B is designed for a mission life of 12 years.

12 Ku-band transponders with 36 MHz and 27 MHz usable bandwidth (9 and 3 numbers respectively) employing 140 W TWTAs to provide an EIRP of 52 dBW at Edge Of Coverage (EOC) polygon with footprint covering Indian mainland.

12 C-band transponders with 36 MHz usable bandwidth employing 63 W TWTAs to provide an EIRP of 39 dBW at EOC with expanded coverage encompassing Indian geographical boundary, area beyond India in southeast and northwest regions.
