Highly Integrated 

The MFREU combines Trident’s xDRT modules with support modules for a complete unit-level solution. Based on our powerful, flexible multifunction process architecture, programmability over all key RF/Processing features is available in a very small size, weight, and power footprint. SpaceVPX compatibility provides modularity, scalability and simplifies integration of peripherals and additional capability.

Highly Reliable 

TRL9 on several LEO missions, a proven Radiation Effects Mitigated architecture, coupled with radiation-tolerant components, redundancy and a robust mechanical design, provide a low C-SWaP, high reliability platform for operation in harsh orbital and interplanetary environments.
