On-orbit No-contact Anomaly Debug Procedure for the CuPID Cubesat

The CuPID CubeSat Observatory was a 6U cubesat launched into low-Earth orbit with a ride-share opportunity in Fall 2021. The mission was supported by NASA's Heliophysics division and motivated scientifically with the objective to image X-rays produced in the magnetosphere. After launch, the team was unable to communicate with the spacecraft. This document presents the testing and analysis of attempts to contact the spacecraft and investigation to the likely cause of failure with the radio system.
