Stellar Computing system

Overview

The Stellar flight computer system is a complete solution to controlling your spacecraft and its data. It offers highly dependable and highly available flight control and data management for all small and medium-sized spacecraft, in any orbit.

Due to its modular design, the system can be tailored to your specific use case, avoiding power, cost and mass overheads

while maintaining the functionality and performance you need. It features high performance for its size and power consumption. Depending on need, different modules are combined to yield a perfectly suited computation and control solution for your mission.

As part of the Bradford Avionics Stack, the Stellar family of computers can be provided in a single unit with other key spacecraft functions, dramatically reducing integration risk and effort.
