The JERS satellite was launched in 1992 and was retired in 1998. The satellite had a 570-km orbit and carried two sensors: Optical Sensor (OPS) and SAR. The SAR polarization is HH. The OPS sensed in the visible and near-IR portions of the electromagnetic spectrum. Both instruments had a swath width of 75km. The satellite's repeat cycle was 44 days.
An interesting feature of the OPS was twin near-IR channels. Band 4 was pointed 15° forward, so when combined with band 3 this instrument could provide stereo imagery in the near-IR.
| Band | Frequency (GHz) | Resolution (m) |
| SAR L | 1.275 | 18 |
| Band | Wavelength Region (µm) | Resolution (m) |
| 1 | 0.55-0.60 | 18 |
| 2 | 0.63-0.69 | 18 |
| 3 | 0.76-0.86 | 18 |
| 4 (15° forward) | 0.76-0.86 | 18 |
