8 General Experiment Support Activities Experiment Support for JPL GPS Experiment #4 –JPL PI reviewed initial Ground Integration Unit (Engr. Model) L5 GPS captures and has identified a concern on the L5 signal – appears lower than expected. –The GRC STB team troubleshot the L5 signal level on the GIU GPS L5 GPS signal was about 20db less than the L1 and L2 GPS signals at the GIU –JPL PI specified alternative L5 antenna and support equipment, which STB generated work order, process plan and CR Completed the following documents for project review (RRB Milestones): – JPL EM Characterization Report (RPT-0952) – Harris FM Databook (RPT-0950) – see plot on next chart – GD EM Characterization Report (RPT-0954) Working on antenna characterization post-processing routines. Restarted WSC SDR work –New GSFC lead and technical team members fully staffed and on board –WSC SDRs that will be delivered at GRC and WSC will be long-term solution to receiving direct C/No measurements –Rework schedule for the delivery of the radios to GSC and WSC – delivery to GRC and WSC by end of FY13 8
