3. 3 Alexei Klimentov. AMS TIM @ CERN. Apr 2005. AMS-02 Ground Support Systems Payload Operations Control Center (POCC) at CERN (first 2-3 months in Houston) CERN Bldg.892 wing A “control room”, usual source of commands receives Health & Status (H&S), monitoring and science data in real-time receives NASA video voice communication with NASA flight operations Backup Control Station at JSC (TBD) Monitor Station in MIT “backup” of “control room” receives Health & Status (H&S) and monitoring data in real-time voice communication with NASA flight operations Science Operations Center (SOC) at CERN (first 2-3 months in Houston) CERN Bldg.892 wing A receives the complete copy of ALL data data processing and science analysis data archiving and distribution to Universities and Laboratories Ground Support Computers (GSC) at Marshall Space Flight Center receives data from NASA -> buffer -> retransmit to Science Center Regional Centers analysis facilities to support geographically close Universities
