China launched five new small remote sensing satellites on Thursday using a Long March 11 (Chang Zheng 11) rocket. The launch of the Zhuhai-1 Group-3 satellites took place at 06:42 UTC on September 19 from a mobile platform at the Jiuquan Satellite Launch Center.
Onboard were four hyperspectral satellites and one video satellite comprising the Zhuhai-1 Group-3.
The Zhuhai-1 remote sensing micro-satellite constellation is a commercial satellite constellation built and operated by Zhuhai Orbita Aerospace Science and Technology Co., Ltd.
The first satellites of the Zhuhai-1 satellite constellation were launched in 2017 and 2018 respectively, initiating the launch and operation of satellite constellations by private companies in China.
The constellation is composed of video and hyperspectral satellites. The video satellites have a launch mass of 90 kg and feature a high-resolution video system for earth observation with a spatial resolution of 0.9 m and a swath width of 22.5 km. It can capture video sequences of 120 seconds.
In push-broom mode, it can capture images of 2500 km length. The hyperspectral 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 × ...
