The ultra-low-orbit series payloads are specially developed for satellites operating at ultra-low Earth orbits of 100–300 km. Leveraging the advantages of near-Earth orbit, the lightweight camera body enables high-resolution ground imaging with a spatial resolution of 0.2~0.5 m, alongside a full suite of multispectral spectral bands.Optimized
in structural design and coating technology to withstand low-orbit atomic oxygen and aerodynamic temperature fluctuation environments, the product features on-board real-time preprocessing and high-speed downlink capabilities with outstanding revisit efficiency. Compatible with CubeSat and small-satellite platforms, it is widely applied in emergency monitoring, natural resource inventory, urban mapping and other fields.
