Chinese Amateur Satellite Group (CAMSAT) has announced the impending launch of the CAS-7B satellite, also designated as BP-1B, a short-lived spacecraft that will carry an Amateur Radio payload. An unusual feature of the spacecraft is its “sail ball” passive stabilization system. The 1.5-U CubeSat is attached to a 500-millimeter flexible film ball — or sail — that will offer passive “pneumatic resistance” stabilization. CAS-7B is expected to remain in orbit for up to 1 month.
The spacecraft will carry an Amateur Radio transponder and educational mission. CAMSAT is working with Beijing Institute of Technology (BIT), a top aerospace school, which is providing launch support in launch of the satellite. BIT faculty and students are participating in the development and testing of the satellite, and, with CAMSAT’s help, the university has established an Amateur Radio club (call sign BI1LG). CAMSAT said many students are now members, “learning Amateur Radio satellite communication and experience[ing] endless fun.”
