Microsat Systems Canada Inc.
Canadian builder of microsatellites and attitude control hardware including reaction wheels and rate measurement units
Microsat Systems Canada Inc. (MSCI) builds microsatellites and develops attitude control system hardware — reaction wheels and rate measurement units — for military, civil, and commercial space customers. The company traces its lineage to the team originally assembled in 1975 to support dynamics and control work on the NASA Space Shuttle robotic arm and later the International Space Station; that group became Dynacon Inc. before David Cooper spun out the space division to form MSCI in 2008. MSCI served as prime contractor to the Canadian Space Agency for the MOST space telescope, launched June 30, 2003, and for the NEOSSat microsatellite. The Canadian Space Agency selected the MSCI microsatellite design as the baseline for its Multi Mission Microsatellite Bus. MSCI now owns and operates the MOST satellite and continues to apply variants of the NEOSSat bus for additional missions. The company is based in Mississauga, Ontario.
