3
3 PFP QSR, 1/19/2011 Schedule Status While lots of progress is bring made and the team is at full strength, we are still showing some slippage in getting the EMs together Have re-arranged the EM schedule to get the system electrical functional done as soon as possible, putting off the EM STATIC and SWIA instrument calibrations (which now don’t complete till after instrument PDR) Looking at ways to break bottle-necks –Recently hired another technician and an additional test engineer –Have identified potential help at GSFC in winding EM magnetics Some erosion of post-CDR schedule margin –Due to late EM I&T –STATIC, PFDPU –Still have 16 weeks of margin to delivery on critical path –Working on ways to improve margin
4
4 PFP QSR, 1/19/2011 Manpower RBSP-EFW instrument approaching delivery –Most of the people we need have transitioned 100% –a few still completing tasks, notably a key technician –Hired an extra technician this month Solar Probe Plus is starting to impact a few team members –Looking at ways to share and augment team as needed
5
5 PFP QSR, 1/19/2011 Accomplishments All required EM EEE parts at SSL All flight Active parts are on order –Passive parts list being updated, ordering in progress Most PWBs layed out, some loaded and in test –see below DCB loaded, in test –Key element for EM I&T with LM in April Most EM Mechanical parts are in fab –Some part-level design work still in progress on SWIA/STATIC PFDPU simulator GSE delivered to GSFC, LASP, SSL Instrument teams More in instrument sections…
