The 25KG satellite platform fully guarantees the functional safety of the platform. The on-board computer, power subsystem, and communication system adopt a redundant design, making the entire satellite more reliable.
The 25KG satellite platform adopts a dual-cabin design, which has higher space utilization and richer energy equipment. The payload bay accounts for about 50% of the entire satellite volume, and the peak power consumption can reach 130W. It can complete the on-orbit verification mission of dual payloads, and has currently completed the mission of carrying payloads such as remote sensing cameras, laser communication machines, and VPX integrated processors.
The 25KG satellite platform adopts a multi-sensor attitude confirmation method of star sensitivity + hypersensitivity + magnetometer + GPS + IMU, and also uses a high-precision momentum wheel with a torque control accuracy of ≤0.1mNm to ensure that the attitude stability of the entire satellite is <0.05°/ s, the pointing accuracy is better than 0.1°. The entire satellite can swing in a small range, assisting laser communication machines and other equipment to complete communication docking.
The 25KG platform has good scalability, stable interfaces for payloads, and abundant energy. Core payloads can be flexibly selected according to mission requirements and support multiple types of aerospace missions.
