Radiation-Tolerant Space Data Acquisition

Cost Savings of COTS in a Reliable, Radiation-tolerant System

Leveraging rugged, commercial off-the-shelf (COTS), space-qualified data acquisition systems doesn't mean sacrificing reliability in high-radiation environments, such as low earth orbit. Our radiation-tolerant chassis and COTS modules are designed to reduce risk while delivering the size, weight, power, and cost (SWaP-C) benefits of commercial designs. The system backplane is designed to reset modules when faced with a single event latch-up (SEL), can switch modules on and off for optimal power budgeting, and provides continuous health status information and a watchdog capability.
