1. A radiation tolerant software defined radio device for multi-band radio applications in space systems comprising components designed for terrestrial application, the components comprising
a power supply,
a base band processor,
volatile and non-volatile memories,
a radio frequency transceiver having a driver allowing for software-based reconfiguration of various radio frequency characteristics including local oscillator frequency, analog filter bandwidth, gain control of input and output amplifiers, sample rates of analog-to-digital converters and digital-to-analog converters, and
mitigation mechanisms on hardware and software level for autonomously recovering to a nominal state wherein the hardware level mitigation mechanism comprises confirming that voltage fluctuations do not exceed component voltage tolerances and software level mitigation mechanism comprise verification of the continued presence of a heartbeat signal and restarting the system if the heartbeat signal is no longer present.
