GSLV-F06 / GSAT-5P Mission at a Glance

GSAT-5P

GSAT-5P is the fifth satellite to be launched in the GSAT series. It is an exclusive communication satellite to further augment the communication services currently provided by the Indian National Satellite(INSAT) System. Weighing 2310 kg at life-off, GSAT-5P carries 24 C-band and 12 Extended C-band transponders.

It will be launched  from Satish Dhawan Space Centre SHAR, Sriharikota by India’s Geosynchrounous Satellite Launch Vehicle(GSLV-F06) into a Geosynchrounous Satellite Transfer Orbit(GTO)  with a perigree of 170km and an apogee of 35,975km inclined at an angle of 19.3 deg to the equator. The satellite then manoeuvred to its final circular 36,000km high Geostationary Orbit by repeatedly firing the Liquid Apogee Motor(LAM) on board the satellite . GSAT-5P will be stationed at 55 deg East longitude.

SALIENT FEATURES of GSAT-5P:

• Orbit : Geostationary(55 deg east longitude)
• Dry Mass : 975 kg
• Lift-off Mass : 2310 kg
• Spacecraft Propulsion : 440 N liquid Apogee Motor with MON-3(Mixed Oxides of Nitrogen) and MMH(Mono Methyl Hydrazine) for orbit raising
• Power : Solar array generating 2600 W, Two 64 Ah Lithium-Ion batteries to support full payload operation during eclipse period
• Mission life : 13.7 Years

GSLV-F06

GSLV-F06 is the 7^th mission of GSLV aimed to inject a 2310 kg communication satellite, GSAT-5P, into a Geosynchrounous Satellite Transfer Orbit(GTO). GSLV is a three stage rocket....

1. First stage is configured around a core 139 tonne solid rocket motor (S139) with liquid strap-on stages each carrying 42 tonnes of earth storable liquid propellants: UH25 and N₂O₄ . S139 Solid booster uses Hydroxyl Terminated Polybutadiene (HTPB) based propellant.
2. Second stage is a liquid stage with 39.4 tonnes of liquid propellants UH 25 and N₂O₄ .
3. Third stage is a cryogenic stage with 15.2 tonne propellant loading using liquid Hydrogen as fuel and liquid Oxygen as oxidizer.
