1. CRaTER Test and Verification Plan

Boston Univ.

2. Environmental Verification Matrix

3. CRaTER Ground Support Equipment I: Command and Data Simulator
Will consist of 1.) a spacecraft simulator with 1553 to Ethernet conversion, a 28 V power supply, a 1 Hz signal, and 2.) a personal computer with dedicated software
Point-to-point TCP/IP socket will be employed for commands
ITOS is not preferred for dedicated software development, as it includes ITAR requirements incompatible with academic environments
Future trade study will determine software choice, e.g., PearlTK, LabView, etc.
Only real time spacecraft simulator mode is relevant for CRaTER

4. CRaTER Ground Support Equipment II: Gas Purging
All sensitive equipment (e.g., telescope, detectors) will be stored under clean, low-humidity conditions (e.g., active dessication, purging)
Flight units will have provision for clean, dry nitrogen purging
Purge flow will be monitored with a thermistor
