SpaceWire Avionics product suite

SpWAvionics

ÅAC SpaceWire Avionics products meet increasingly demanding requirements on reliability, resilience and low power consumption. Their form factor, mass and dimensions make them attractive for the small satellite and launch vehicle segments that need to reduce the size and mass of their power and data handling sub-systems. The capacity for onboard data handling, data storage and data transfer meets the current trend towards more advanced missions in smaller spacecraft.

• Reliable high-performance space data handling and processing avionics
• Tolerant to single-event effects through triple-modular redundancy and errorcorrecting codes
• RTEMS real-time operating system (RTOS) on 50 MHz OpenRISC soft CPU
• Thoroughly qualified with environmental tests for space
• Mechanical CubeSat and microsatellite compliance
• Innovative harness routing solution
• 24-bit A/D converter
• SPAready
