A mock-up for the development of the Engineering Model (EM) and Flight Model (FM) is introduced which shortens the delay of 7 weeks regarding the previous planned launch date of September 30, to about 3 weeks maintaining the 4 weeks reserve is discussed. As compared with the new assembly integration test (EM-AIT) schedule of March 11, 1985, the EM data handling system is on the critical path. For the attitude measurement and control subsystem, sufficiently flexibility is achieved through combination of dummies and EM hardware to catch up with the existing delays.
