SuperView
The SuperView (GaoJing) satellites are the first “very high-resolution” Earth observation spacecrafts, designed in China. Apart from two solar panels, they are equipped with sensors collecting imagery of both panchromatic and multispectral resolution with a maximum 60 km x 70 km single scene. The constellation is very agile and operates in four acquiring modes:
stereo imaging
long strip
multiple strips collect
multiple point targets collect
The SuperView-1 (SV-1) consists of four Chinese commercial remote sensing satellites and offers satellite imagery with 0.5-meter panchromatic resolution and 2-meter multispectral resolution on a swath of 12 km. The spacecraft is very agile providing multiple collection modes including long strip, multiple strips collect, multiple-point targets collection, and stereo imaging. The program's main objective is to provide data to be applied in defense and intelligence, land and forestry management, high accuracy mapping, security, and maritime programs.
SuperView-2 (SV-2) is a follow-on satellite of the SV-1 satellite constellation. It is a very-high-resolution optical imaging satellite. Compared with SV-1 satellites, SV-2 provides higher resolution and more spectral bands. The satellite has one panchromatic band and six multi-spectral bands. The panchromatic resolution is 42 cm and the multi-spectral resolution is 1.68 m at nadir. The imagery collection is highly agile, as the satellite allows multi-target, long-strip, multi-angle at one target, multi-strip, bi-/tri-stereo, along/not-along track collection in one single pass. The satellite is equipped with a set of synchronous monitoring atmospheric correctors to remove the effects of the atmosphere on the reflectance values of images.
