Microsatellite Bus MP42

MP42 microsatellite buses are available in three different configurations:

MP42 – standard microsatellite bus.
MP42H – the smallest and lightest configuration offers starting empty bus mass just from 18 kg.
MP42D – the biggest microsatellite bus offers spacious payload envelope 740 x 730 x 500*. (*satellite height is highly adjustable to customers payload requirements, up to 1300 mm)

Hardware and software of NanoAvionics satellite buses MP42, MP42H and MP42D, as well as mission operations infrastructure, are established on baseline architecture and mission-specific “building blocks” for flexible, time & cost-efficient integration, resulting in wide applicability, reliability, repeatability and manufacturability.

MP42 buses are highly versatile – their performance capabilities are optimized for remote sensing, high data throughput & complex communications missions, emergency communications, and fundamental research missions. All requiring minimal reconfiguration.

MP42 buses can include a propulsion system that enables the satellite to perform 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.

Microsatellite General Features:
MP42:
- Total empty bus mass: from 45 kg (depends on configuration).
- Maximum satellite mass: 120 kg* (depends on configuration and Payload Mass Properties).
- MP42 Payload Envelope: 490 x 480 x 350* mm (*satellite height is highly adjustable to customers payload requirements, up to 1300 mm).
MP42H:
- Total empty bus mass: from 18 kg (depends on configuration).
- Maximum satellite mass: 40 kg* (depends on configuration and Payload Mass Properties).
- MP42 Payload Envelope: 280 x 325 x 280* mm (*satellite height is highly adjustable to customers payload requirements, up to 1300 mm).
