Implementation of Real-Time Hardware in the Loop Simulation for WAVE Instrument Avionics

Al Qaraghuli, Ali

The Regolith and Environment Science and Oxygen and Lunar Volatile Extraction (RESOLVE) payload will lead the Resource Prospector rover to hydrogen-rich locations on the moon supporting NASA's in-situ resource utilization (ISRU) mission. The Water Analysis and Volatile Extraction (WAVE) system will be responsible for heating up regolith samples and analyzing their volatiles in a vaporized state. Given the space environment, testing flight hardware and software using the scientific instruments can be costly and time consuming, which can hold back progress involving the instruments. A hardware-in-the-loop (HITL) simulation will test the Avionics Data Acquisition as well as the Instrument Interface Unit, through simulating sensors and actuators involved in supporting the WAVE instruments. HITL is a platform for testing and developing WAVE's avionics and software, where the simulation plant will imitate the LAVA and OVEN instruments, thus allowing for an accessible, efficient, and replicable testing environment.
