Indian Remote Sensing Satellite. Remote sensing of the Earth for natural resources management applications. Earth Observing satellite for ISRO, India. Launched 1988-1991. Used IRS-1 Bus.

AKA: Cartosat;Megha;Resourcesat. Status: Operational 1988. First Launch: 1988-03-17. Last Launch: 2012-04-26. Number: 16 . Gross mass: 1,250 kg (2,750 lb).

Data from IRS satellites was received and processed by the National Remote Sensing Agency, Hyderabad. The US company SI also received and marketed IRS data worldwide under a commercial contract with the Antrix Corporation of the Indian Department of Space.

IRS-P6 was the tenth satellite of the IRS series, and carried three cameras similar to those of IRS-1C and IRS-1D but with improved spatial resolutions:

  • A high resolution Linear Imaging Self Scanner (LISS-4) operating in three spectral bands in the Visible and Near Infrared Region (VNIR) with 5.8 meter spatial resolution and steerable up to plus/minus 26 deg across track to obtain stereoscopic imagery and achieve five day revisit capability
  • A medium resolution LISS-3 operating in three spectral bands in VNIR and one in Short Wave Infrared (SWIR) band with 23.5 meter spatial resolution
  • An Advanced Wide Field Sensor (AWiFS) operating in three spectral bands in VNIR and one band in SWIR with 56 meter spatial resolution.

IRS-P6 also carried a Solid State Recorder with a capacity of 120 GigaBits to store the images taken by its cameras, which can be read out later to the ground stations.

Salient Features:

  • Orbit: Circular Polar Sun Synchronous
  • Orbit height: 817 km
  • Orbit inclination: 98.7 deg
  • Orbit period: 101.35 min
  • Number of Orbits per day: 14
  • Local Time of Equator crossing: 10.30 a.m.
  • Repetitivity (LISS-3): 24 days
  • Revisit (LISS-4): 5 days
  • Lift-off Mass: 1360 kg
  • Attitude and Orbit Control: 3-axis body stabilized using Reaction Wheels, Magnetic Torquers and Hydrazine Thrusters
  • Power: Solar Array generating 1250 W, Two 24 Ah Ni-Cd batteries
  • Mission Life: 5 years
