OPAL Action Items

• Payloaders need to inform Buckley of any hazardous materials or situations on their satellites ASAP
• Payloader phone call every Friday at 1 pm.
• We need to provide our predicted separation velocity to Weber
• We need to provide them our interface mass characteristics to Weber
• CSA needs higher fidelity FEM by 1 October, then updated models throughout the year
• December 1 is hard deadline for any major payload mass changes
• We need to identify uses of the extra lines prior to the Orbital CDR in early September if possible
• We need to spec nuts and bolts rather than helicoil if desired for the interface
• Weber needs a mass model for the first JAWSAT shake – we can provide or they will make a crude one to use
• CSA needs cgs, fundamental frequencies, and 1st bending modes within 5-10%
• Identify any sensitive points on the satellite, mark, and tell CSA
• Need 150 ft. of extension cord and power supply at launch pad, need to provide specs on required power conditioning at launch vault
• Possibility of using one of the discreets to launch the picosats
• What do we do with the solar panel power after the shroud comes off before we launch?

Consider redundant microswitches

Buckley

• Payloaders need to provide equivalent mass model in case can’t deliver satellite
• He will not allow the launch vehicle schedule to be affected by microsats not being ready
• We cannot show any connection to a commercial organization
• Must only refer to the launch vehicle as the “Minotaur” in internal communication – it is called the OSP Space Launch Vehicle
• Payloader phone call every Friday at 1 pm.
• Payloaders need to inform him of any hazardous materials or situations on their satellites ASAP

Weber

• ftp access will soon be available through Weber’s web site, in mean time ftp host:
host:  cast.weber.edu
userid:  jawsat
password:  jawsat
• Can access MS Access database to get all the JAWSAT drawings and documentation
• Weber to define the geometry of JAWSAT to facilitate charging of the microsats

Access Doors:

• 2 doors to be provided each 8.5x13” at 180 degrees opposed positions in the center of the JAWSAT profile with the corner of JAWSAT at the door to allow access to satellites on both sides
• Need to use charging connectors designed for blind mates to prevent bent pins – specs to be sent later
• We will be able to charge on the launchpad through the access doors up until 2 weeks before launch, possibly longer
• When on the pad, the launch vault is 25 ft from the base of the pad; we need to bring a power supply and 150 feet of extension cord to run to OPAL

General

• Launch loads to be 10g axial and 5g lateral – revised launch environments document due to be released 8/28/98

Interface Control Document:

• JAWSAT drawings will be sent out electronically with additional dimensions called out to give the volume of the bay
• They will provide bolts to attach our interface with a helicoil and both sides of connectors; we can spec nuts and bolts rather than helicoil
• We need to provide our predicted separation velocity to Weber
• Weber needs a mass model for the first JAWSAT shake – we can provide or they will make a crude one to use
• Paul Chapman is over the electrical interface at Weber, Gary Shirey over the mechanical
• We need to provide them our interface mass characteristics to Weber
• We changed our total mass estimate to 40 lbs

Separation Confirmation

• There will be one connector for ordnance and one for telemetry, both of which they will provide
• We need to identify uses of the extra lines prior to the Orbital CDR in early September if possible
• Video from JAWSAT will be stored for later downlink
• We requested another discreet for separation confirmation and an analog line
• Consider redundant microswitches
• Possibility of using one of the discreets to launch the picosats
• What do we do with the solar panel power after the shroud comes off before we launch?

Finite Element Model

• CSA needs higher fidelity FEM by 1 October, then updated models throughout the year
• Model should have 200-300 nodes total
• CSA needs cgs, fundamental frequencies, and 1st bending modes within 5-10%
• Identify any sensitive points on the satellite, mark, and tell CSA
• December 1 is hard deadline for any major payload mass changes

Schedule

• 1st week October 1998   next payload integration meeting in conjunction with Orbital CDR October 6-8
• 1 December   High fidelity physical mass model to Weber (correct cg, approximate moments) for shake (Weber not doing thermal vac)
• 1 May   Flight hardware delivery to Weber
• 1 June   JAWSAT shake
• 1 July   delivery to Vandenberg
• 3 weeks before   encapsulation
• 2 weeks before   on pad
• 1 September   launch (can slip no later than 15 September)
