HDEV monitors the rate at which HD video camera image quality degrades when exposed to the space environment (mainly from cosmic radiation damage) and verifies the effectiveness of the design of the HDEV housing for thermal control. There are two main types of radiation effects Total Ionization Dose (ITD), and Single Event Effect (SEE): 1. Total ...
