Satellite characteristics

Launch Date - End 11 februari 1992 - 11 oktober 1998

Status Decommissioned

Orbit type Sun-synchronous subrecurrent polar orbit

Altitude 568

Orbit inclination 97.7

Equatorial crossing time 10:30:00

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.
