Microsatellite Bus MP42H

Despite decreases in launch costs, the size and weight of a satellite are still very important defining characteristics in the development of a mission or service. The MP42H is NanoAvionics’ smallest and lightest microsatellite bus, ideal for complex communications missions, and comes with an 15″ ESPA-class separation ring for deployment in orbit.

This pre-designed versatile system allows users to focus more on high-value tasks such as payload integration and testing. It can accommodate payloads with a total mass of 25 kg and a maximum footprint of 410(L) x 392(W) x 330(H) mm. Payload height is flexible, as long as the total satellite height does not exceed the launch vehicle’s available volume.

Despite being only slightly larger and heavier than most higher-end nanosatellites, the MP42H can provide far greater mission capabilities and redundancy opportunities. Thanks to the extra avionics volume, better thermal management, and larger payload interface, it offers significantly more capabilities for only a marginal price increase.

NanoAvionics offers three MP42H microsatellite standard performance configurations – Light, Mid, and Max – providing options that best match customers’ payload mission objectives and budget.

As with all of NanoAvionics’ proven platforms, the MP42H is a highly modular system. Configurable subsystems and operational protocols enable faster setup. The system also has a sample mission code pre-installed so that testing can commence immediately upon delivery.

The MP42H bus is well-suited for single-satellite missions or as the standardized platform for an entire constellation. It is highly versatile and optimized for remote sensing, high data throughput, and complex communications missions, emergency communications, and fundamental research missions.
