Zhuhai-1 OVS 1A, 1B (Zhuhai-1 01A, 01B / CAS 4A, 4B)

Zhuhai-1 (OVS-1) [Zhuhai Orbita]

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

Two OVS-1 satellites will constitute the prototype OVS-1 video component. The operational Orbita constellation is to consist of ten video satellites (OVS-2), hyperspectral satellites (OHS-2) and small personal satellites (OPS-2).

Both satellites feature a high-resolution video system capable of capturing 20 frames per second and reaching a 1.98-meter ground resolution. The satellites carry each a linear transponder payload for CAMSAT, which are called CAS 4A and CAS 4B respectively.

The first two video satellites were launched as secondary payloads on a CZ-4B rocket in 2017.
