WEEKLY HIGHLIGHTS FOR WEEK ENDING 8 August 1997:
Steve Larsen, Paul Lassa, and Mike Eglington from the Gyroscope Suspension System group have reduced the suspension loop execution time on the RAD6000 processor from 2000 microseconds to less than 500 microseconds. This is compatible with a 2kHz control rate, and therefore with ground levitation capability. The improvements were made by removing the VX Works task manager and rewriting the square root algorithm for the RAD6000. The RAD6000 processor is the engineering unit for the GP-B flight suspension and readout electronics systems.
Phase 3 of the Probe-C Integration has been successfully completed. The Top Hat was successfully bonded onto the Probe-C assembly on 29 July. After a 24-hour cure, the instrumentation cables were connected inside the top hat, and the strongback was bolted on over the composite neck tube to provide structural support for the composite tube, completing Phase 3 Integration. The effort represents a big milestone for the Probe team.
The probe is now ready for Phase 4 integration. Phase 4 and final test represent a three month effort culminating in delivery of the probe to Stanford.
Contract deliverables and draft presentation material have been completed and submitted to Stanford University for the second Relativity Mission Spacecraft Critical Design Review (CDR 2). Fifty three documents and one hundred sixty nine released drawings were delivered to Stanford.
