SAST-3000
Based on mature technology and high reliability, the configuration of SAST3000 not only suitable for safety and stability of traditional biased momentum control,but also characterized by high accuracy and stability of three-axis stabilization. The good expandability and adaptability of the platform allows easy installation of payloads like microwave and optical remote-sensing instrument etc. With the capability of remote sensing, data collection and science test, SAST3000 can be used for LEO, MEO and HEO missions. 14 satellites based on SAST3000 have been sent into orbit and Kept stable operation for over 2000days.
The Platform SAST3000 for LEO earth observation missions has enjoyed phenomenal success with over 7 satellites, including FY-3、YaoGan-1, with advantages of high accuracy, high power supply, modular design, flexible to extend function, low rick and cost.
