Satrec Initiative: SI-200

RazakSAT [Satrec Initiative]

SI-200 bus system is based on the RazakSat (aka MACSAT) bus technology, which is being jointly developed with ATSB of Malaysia for its national space program. SI-200 bus is designed for Low Earth Orbit small satellite missions. It can accommodate various kinds of payloads for electro-optical Earth observation, telecommunications, and space science by offering relatively large payload space. This bus system can be flexibly re-configurable to adapt different mission and user requirements. This system is an attractive platform for small satellite missions with the following characteristics:

• Compact hexagonal frame structure
• Affordable volume and mass for small satellite launchers
• Active full 3-axis attitude stabilization
• High reliability system with redundant design concept
• High speed data downlink capability for complex payloads
• 2.5m resolution remote sensing payload (MAC) on-board as baseline design
