The 5m Multispectral camera was launched into orbit aboard the Wenchang-01/02 satellites on February 27, 2022, serving as the primary payload of Wenchang-1. Weighing approximately 6.5kg, it provides a swath width greater than 115 km. The camera enables high-resolution Earth observation and offers comprehensive, operational monitoring of Hainan Island and its surrounding waters. It supports the island’s spatial data needs in key areas such as natural resources, agriculture, forestry, marine environment monitoring, maritime shipping, emergency search and rescue, and fisheries information services. The system serves government departments in natural resources, agriculture, forestry, marine affairs, and environmental protection, as well as key cities and counties including Haikou, Sanya, and Sansha. By providing highly detailed spatial awareness, it contributes to the development of the Hainan Free Trade Port and the protection of marine resources.
