Payload Integration Working Group Meeting
Deceber 2, 1998 
Vandenberg Air Force Base, CA

OPAL Action Item Summary

  • review payloader ICD matrix, return to OSSS
  • we need to get the switches for our separation confirmation signal
  • get freq. license, get the info on it to Buckley
  • post test info on web
  • add beacon specs to ICD for the after-separation pulse


Notes summary:

JAWSAT

  • integration order:  ASU, OPAL, OCS, Falconsat, MSFC
  • need information from payloaders on required check-out tests after integration
  • preferable to have payload people at WSU for integration help
  • payloaders can turn on their radios for check-out tests at WSU and in EPF at VAFB
  • payloads will be trickle-charged as long as possible on the pad, possibly up to 1-2 days before launch
Falconsat
  • right now not planning to turn on if not deployed, but PI trying to change that
OCS
  • orbit data:
    alt:  750 km
    inc:  100 degrees
    RA:  265 degrees
    ecc:  0
    epoch: Sept. 15, 1999
CSA
  • will need payloader mass models again in March
  • should have design for SoftRide in about 3 weeks
Buckley
  • all payloaders and OSSS need to operate together as "one harmonious organism"
  • OSSS and Buckley to talk about how to reduce costs -- may not need to meet so often as a group
OSC
  • the 14 g axial and 8.7 g lateral transient loads are for a 300 lb payload and will be less for the 400 lb JAWSAT
  • the two shocks in table 1 of the new loads data are for JAWSAT-4th stage separation -- payloads will never see this
  • proposed preliminary sep sequence:  ASU, OPAL, OCS, Falconsat, JAWSAT
 General
  • possibility of having pre-ship review at VAFB at end of April, could bring OPAL to meeting, have OSSS take it back
  • ejection velocities should be a low as possible, with .5 ft/s being the lowest allowed
  • WSU has frequency allocation without a license, may launch without the license and let the license catch up after launch
