GSAT is the Geostationary Satellite which is a set of communication satellites developed by India and used primarily for audio and video broadcasting.
INSAT stands for Indian National Satellite System which is a program by ISRO with the aim of providing services to fields such as disaster management, weather forecasting and telecommunications.
GSAT-10 was launched from Kourou, French Guiana, South America on September 29, 2012. It was placed in Geosynchronous Orbit at 83 degrees East longitude. It made use of I-3K Bus system.
The propulsion system consisted of a 440 Newton Liquid Apogee Motors (LAM) with mono Methyl Hydrazine (MMH) as fuel and Mixed oxides of Nitrogen (MON-3) as an oxidizer for orbit raising. For Attitude Determination and Control System (ADCS), it makes use of eight 10 Newton and eight 22 Newton bipropellant thrusters, Momentum and Reaction Wheels, Magnetic Torquers. There are also onboard sensors - Earth Sensors and Sun Sensors. The satellite will be powered by a primary source consisting of a solar array capable of providing 6474 watts and a secondary source consisting of two 128 Ah Lithium-Ion batteries.

DESIGN AND PAYLOADS:
GSAT-10 carried a two-channel GPS Aided Geo Augmented Navigation (GAGAN) payload. GAGAN is a system used to improve the accuracy of GNSS receiver which is a part of Satellite-Based Augmentation System (SBAS). Two-channel chosen for GAGAN in this mission are L1 and L5. A 0.8m x 0.8m L-band helix antenna will be used for this communication. Twelve C-band and six extended C-band transponders are also onboard
GASAT-10 also carried twelve high power transponders working on Ku-band. This is achieved by using two 2.2m diameter deployable reflectors. GSAT-10 is the second satellite in INSAT/GSAT constellation (GSAT-8 was the first launched in 2011)
