GSLV-F10/GISAT-1 MISSION

MISSION DESCRIPTION

TARGETED GEOSYNCHRONOUS TRANSFER ORBIT

India’s Geosynchronous Satellite Launch Vehicle-F10 (GSLV-F10) will launch Geo Imaging Satellite-1 (GISAT-1) satellite from the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launch will take place from the Second Launch Pad.

In this flight, a 4 metre diameter Ogive shaped payload fairing (OPLF) is being flown for the first time in GSLV to accommodate a larger spacecraft.

GISAT-1 is the first state-of-the-art agile Earth observation satellite which will be placed in a Geosynchronous Transfer Orbit by GSLV-F10. Subsequently, the satellite will reach geostationary orbit using its onboard propulsion system.

SALIENT FEATURES

GISAT-1 is the first state-of-the-art agile Earth observation satellite from Geostationary orbit.

Objectives• To provide near real time imaging of large area region of interest at frequent intervals• For quick monitoring of natural disasters, episodic events and any short term events• To obtain spectral signatures for agriculture, forestry, mineralogy, disaster warning, cloud properties, snow & glaciers and oceanography

The Satellite is configured around modified I-2k bus carrying multispectral and hyperspectral payloads in different bands with improved spatial and temporal resolution.
