5kg satellite platform 3U

5KG satellite platform is a highly integrated micro-satellite capable of supporting up to 2U
(3 kg) payload. The satellite platform is equipped with a highly integrated and multifunctional onboard computer.
Integrated flywheel control system, magnetic rod control system, whole-satellite power distribution system, and magnetometer,
Sensors such as gyroscopes. The entire satellite adopts a high-integration design concept to provide 50% of the entire satellite’s carrying space for payloads.

The 5KG satellite platform is “small in size, light in weight, low in price, and has large carrying space” and is suitable for low-profile
Space missions focusing on control requirements (scientific experiments, payload verification, remote sensing, communications, etc.).

The 5KG satellite platform adopts a highly integrated design, and the payload can be used to carry space that occupies the entire satellite volume.
50%. The onboard computer ensures the integrity of the entire satellite function with a high degree of integration. The onboard computer (OBC) integrates the control system of the reaction flywheel, the control system of the magnetic torquer, the magnetometer, the gyroscope, the power distribution and other functions.

The 5KG satellite platform has rich on-orbit verification experience and can be used to perform remote sensing photography tasks with a resolution of 3.7m@500Km.
