Subject: Discussion of DSP issues
Mime-Version: 1.0
Status: RO


     We held a meeting today with the DSP-R software development team. We
     asked that the next revision be delivered by 31 January, a few days
     (intentionally) before the end of the Galileo solar conjunction
     experiment, currently in progress.

     This revision will allow switching to BWG antennas (there might be an
     exception with DSS-25 that needs further work) as well as expanded
     memory on the DSP, the level 3 acknowledgement, and other features.

     The Predict remote ops delivery, that is due in the following delivery
     around April (just before the MGS GWE).

     As far as the problematic POCA behaviour seen by JPL RSSG as well as
     stanford investigators, chances are the corrections in this version
     will not fix all the problems. The missing POCA time tags (followed by
     repeated POCA time tag) may be a SPA-R not RSCP problem and an expert
     in Hal-S language has to be found.

     After a lenghty discussion of all possible cases of POCA time as well
     as frequency reporting problems, we agreed to proceed with the
     delivery due to the other benfits of the version and keep working on
     the POCA issues for the following (funded) delivery.
