About
The OHS is Orbita’s hyperspectral-imaging microsatellite platform, the core payload of the Zhuhai-1 constellation’s spectral-imaging capability. Each 67 kg satellite operates in a 500 km sun-synchronous orbit and captures imagery across 32 spectral bands spanning 400-1000 nm at 2.5 nm spectral resolution, with 10 m ground sampling distance and a 150 km x 2500 km image-scan swath. Two sets of four satellites (OHS-2A/B/C/D and OHS-3A/B/C/D) were launched in April 2018 and September 2019 respectively on CZ-11 rockets from Jiuquan, alongside the OVS-2/OVS-3 video satellites. OHS data is used for agriculture, forestry, water quality, ecological and environmental monitoring, and mineral/land-cover classification.
