Satellite characteristics
Launch Date - End 10 February 1992 - 10 October 1998
Status Decommissioned
Orbit type Sun-synchronous subrecurrent polar orbit
Altitude 568
Orbit inclination 97.7
Equatorial crossing time 10:30:00
Orbit period 96
Satellite family: JERS (Japan Earth Resources Satellite)
The overall objectives call for:
- Generation of global data sets with SAR and OPS sensors in order to survey resources;
- establishing an integrated Earth observation system, verifying instrument/system performances.
The mission applications focus on: survey of geological phenomena, land usage (agriculture, forestry), observation of coastal regions, geologic maps, environment, disaster monitoring, etc.
The spacecraft carries two closely matched Earth observation sensors: the active SAR instrument and the passive OPS multispectral imager.
