6U nanosatellite bus M6P

Download in-orbit performance data here

NanoAvionics’ flight-proven 6U satellite bus is based on a modular and highly integral design. It delivers extends payload volume and saves development costs for customers.

M6P satellite bus enables customers to concentrate on the most important mission goals and deal only with high-level mission implementation tasks, such as payload development, and its support during the mission in orbit.

The standard configuration of the nanosatellite bus is optimized for IoT, M2M, ADS-B, AIS, other commercial and emergency communication applications, and scientific missions.

M6P bus includes a propulsion system capable of performing high-impulse maneuvers such as: orbital deployment, orbit maintenance, precision flight in formations, orbit synchronization, and atmospheric drag compensation. This results in an extended satellite orbital lifetime uncovering new opportunities for unique customer missions and significant savings on constellation maintenance costs.
