WEEKLY HIGHLIGHTS FOR WEEK ENDING 5 March 1999:

STANFORD HIGHLIGHT
GP-B held its fifth System Level Validation Review (SLVR). The meeting went very well with only 4 new action items.

The GSS group under the leadership of Dr. Bill Bencze and Dr. David Manner held a successful peer review for three its most complex boards.

The GPS group lead by Dr. Awele Ndili held a Test Readiness Review (TRR). Once the action items from this review are addressed, testing of the flight box will begin.

SPACE VEHICLE HIGHLIGHT
The Relativity Mission (GP-B) flight computer (CCCA) is in house and will be testing in the Integrated Test Facility (ITF) next week. It is planned to install it on the spacecraft in the following weeks. At that point, the major command and data handling hardware is available to start subsystem testing which is an important milestone in preparation for payload integration.
