WEEKLY HIGHLIGHTS FOR WEEK ENDING 17 October 1997:
Under the direction of Rodger Cliff, the electromagnetic interference (EMI) tests of GTU-2 have been successfully completed, while the final electromagnetic compatibility (EMC) tests will be completed by the end of Wednesday, 10/15/97. The EMI/EMC tests represent the major and most important portion of the GTU-2 integrated system testing. The test results indicate that the resistance to EMI and the compatibility between various payload electronic flight systems are expected to meet mission requirements. Note, that in the Science Mission configuration additional EMI attenuation will be provided by the flight version coating of window #4 and the by sun shade.
Engineers working on the axial lock redesign, the dewar rework planning and the "use-as-is" concept presented their analysis, design status and recommendations to Stanford and NASA MSFC on Wednesday, 8 October. Stanford accepted the recommendation that the program baseline be changed from axial lock redesign and dewar rework to the "use-as-is" approach. Stanford authorized delaying the Probe assembly to allow installation of the "use-as-is" hardware.
Parallel efforts (axial lock redesign, dewar rework planning and the "use-as-is" concept development) will continue - with emphasis on the "use-as-is" approach. The "use-as-is" concept Critical Design Review (CDR) is scheduled for 1 December 1997. At this time a single program baseline will be chosen. (Reeve, 4-5001)
