  2. I&T Support • CRaTER team will retain the expertise necessary to address any issues that arise during I&T, launch, and initial operations: • Digital electronics, spacecraft interfaces, instrument simulator, embedded software: MIT/B. Goeke, D. Gordon • Analog electronics: Aerospace Corp/B. Crain • MOC-CRaTER SOC interface: MIT/P. Ford, BU/E. Wilson, BU/D. Bradford • Assembly Q&A, safety: MIT/B. Klatt

  3. I&T Support • Support during I&T activities at Goddard and KSC • One team member on the road • System experts remain on-call at home institutions to trouble-shoot problems • Basis for I&T support strategy • Instrument and its operation are extremely simple and straightforward • Instrument data available in real-time via Internet • Secondary Science & Housekeeping data flows real-time • Primary Science available via scp file copy • CRaTER Hardware support • EM and Flight Spare units located at MIT • Spacecraft simulator gives real-time internet access for testing

  4. Delivered Simulators • Electrical simulator • First instrument electrical simulator check at Goddard in December 2006—no problems • S/N 11 simulator delivered to GSFC (Jun 2006) • Verified R/T data flow from Goddard to MIT for housekeeping and secondary science packets • Mass simulator • Delivered to GSFC (Jan 2007)
