The "Hainan-1" Constellation features multi-spectral and multi-resolution monitoring capabilities. Specifically, the Hainan-01 Satellite is equipped with a 5-meter-resolution wide-swath camera, which has a 110 km swath width and supports marine moving target tracking. The Hainan-02 Satellite is fitted with a 1.5-meter high-resolution pushbroom and video imaging system, enabling accurate identification of small targets. The Wenchang-01 and Wenchang-02 Satellites adopt panchromatic + 8-band pushbroom technology, with a 115 km swath width, serving sectors including natural resources, agriculture and forestry. Data products of the entire constellation cover visible to near-infrared spectral bands, with a quantization level of 10–12 bits and spatial position accuracy better than 10 meters, meeting the refined monitoring requirements for complex scenarios. In terms of application services, the data products of the "Hainan-1" Constellation have deeply empowered three major sectors: environmental protection, agriculture and forestry. For environmental monitoring, dynamic monitoring of bare soil dust sources, construction waste and nature reserves is conducted to support air pollution control and ecological law enforcement. Agricultural monitoring focuses on crop type identification and supervision of "non-grain conversion" in permanently designated basic farmland, providing data support for food security. Forestry monitoring combines satellite and unmanned aerial vehicle (UAV) technologies to achieve large-scale screening of pine wilt disease and dynamic tracking of forest land resources, enhancing ecological protection efficiency. All services are updated on a monthly or quarterly basis.
