AMS-02 JMDC On-Board Application Software Review Xudong CAI / M.I.T. Mar. 1, KSC

New Changes from the Last Meeting  New data taking procedures which include TDR second step calibration and TAS run.  Changed JBUX space control from space of erase-output pointers to space of input-erase pointers.  Changed to have more flexible control of JBUX pointers include set pointers according to frame time.  Modified new GPS Begin Epoch procedures from Alexei.  Bug fixes and optimization of TTCS, UG control and GTSN monitor tasks.  Optimized circular buffer operations and removed STS-1553 HK buffer. Both STS-1553 and ISS-1553 will share the same buffer because only one will be used at a time. 03/01/2011AMS-02 JAP Software Review2

Conclusion  Level-3 Trigger is not included yet.  CAN bypass mode is not added. We will not need it for the first a few years.  NASA commands tested and got checksum error. We have to decide what to do.  No further development is planned except bug fixes.  More TRD Gas control functions and TTCS control functions will be added when we have experiences in space. 03/01/2011AMS-02 JAP Software Review16
