12U Satellite Bus M12P

12U nanosatellite bus M12P / M12P-R

NanoAvionics’ flight-proven 12U satellite bus is based on a modular and highly integral design. It delivers extended, up to 11U, payload volume and saves development costs for customers.

M12P satellite bus enables customers to concentrate on the most important mission goals and deal with high-level mission implementation tasks only, such as payload development, integration, and support during the mission in orbit.

The standard configuration of the bus is optimized for IoT, M2M, ADS-B, AIS and other commercial and emergency communication applications as well as scientific and Earth Observation (EO) missions.

NanoAvionics also offers a single fault tolerant 12U satellite bus design option – M12P-R. By doubling the critical satellite subsystems, single point failures are removed from the system, hence adding mission reliability and redundancy. Such satellite system is designed to have a mission lifetime of 10 years in LEO.

M12P and M12P-R buses include propulsion system capable to perform high-impulse maneuvers such as: orbital deployment, orbit maintenance, precision flight in formations, orbit synchronization and atmospheric drag compensation. It results in extended satellite orbital lifetime uncovered new opportunities for the unique customer missions and significant savings on constellation maintenance costs.
