WEEKLY HIGHLIGHTS FOR WEEK ENDING 27 November 1998:
The Gyroscope Suspension System (GSS) group's Testing and Verification Team led by Mr. Robert Brumley has finished a series of detailed simulations that indicate that the current GSS design complies with all fundamental science requirements. Because the same electric fields used to control the rotor's position can also create torques that masquerade as relativity, the requirements on the GSS are particularly severe -- requiring subnanometer-level positioning at key frequencies and microvolt stability. The simulations measured the response of the integrated gyroscope-GSS system, and included advanced models of the GSS components, appropriate noise levels, and all steady-state on-orbit disturbances.

A successful Relativity Mission (GP-B) Integration Working Group Meeting was held at Vandenberg Air Force Base (VAFB) on November 18. The Payload Fairing requirements were finalized including five mission-specific 24-inch access doors. Facility space and capability issues were discussed during a tour of the GP-B vehicle processing facility in building 1610, and Program Introduction document comments were exchanged.
