The OHS 1 earth observation satellites are the hyperspectral component of the Chinese Orbita or Zhuhai-1 earth observation system by Zhuhai Orbita Control Engineering Ltd.

The OHS-2 satellites are the hyperspectral component of the constellation. The operational Orbita constellation is to consist of ten video satellites (OVS-2), hyperspectral satellites (OHS-2) and small personal satellites (OPS-2).

These satellites have a ground resolution of 10 m and a swath width of 150 km. The spectral resolution is 2.5 nm. It gab capture images of 150 km × 2500 km in push-broom mode.

A constellation of four satellites can cover the entire globe in 5 days and provide multiple revisits a day of a specific site.

The first four OHS-2 hyperspectral satellites were launched on a CZ-11 rocket in 2018.
