Abstract:

The objective of the MICRON Phase 2A contract was to test N57A-1 and N57A-2 to design, fabricate and integrate two gyro subassemblies and one gyro test station to test gyro and gyro subassemblies and to perform analyses, studies and trade-offs for use in defining the MICRON system. Both N57A systems were flight tested and the capability of the system to meet the position accuracy requirement was demonstrated. N57A-1 was used to demonstrate in-motion polhode damping. System reliability screen, Scorsby and heading sensitivity tests were successfully conducted on N57A-2. Two gyro subassemblies and one gyro test station were designed, fabricated, and integrated. One subassembly was used for MESGA development testing and one was used for 4-plate gyro and electronics development. Getter gyros were fabricated and tested. A gyro design evolved which meets the fast reaction requirement. A small gap gyro was developed which reduces the cost of gyro suspension electronics. System analyses, studies, and trade-offs were made which resulted in circuit simplification, reduced costs, and partitioning to meet maintainability and producibility requirements.
