Observing Systems Capability Analysis and Review Tool
Satellite Programme: Satellite for Earth Resources
Series of operational satellites, for high-resolution land observation.
Indian programme: ISRO responsible of development and operations.
The platforms are actively stabilised over 3 axes.
The design life time is 5 years.
The satellites exploit geosynchronous orbits around 10:30.
The replacement policy is based on launching satellites in sequence, roughly 6 months before the expected end-of-life of a satellite.

Selected images are stored onboard and downlinked to stations of the ISRO network.
Real-time downlink to a network of appointed acquisition stations in X-band.
All data concentrated to the National Remote Sensing Center (NRSC) in Hyderabad for processing and distribution.
