VOLUMEⅡ STANDARDIZED STRAPDOWN INERTIAL COMPONENT MODULARITY STUDY

摘要

To obtain cost effective strapdown navigation, guidance and stabilization systems to meet anticipated future needs a standardized modularized strapdown system concept is proposed. Three performance classes, high, medium and low, are suggested to meet the range of applications. Candidate inertial instruments are selected and analyzed for interface compatibility. Electronic packaging and processing, materials and thermal considerations applying to the three classes are discussed and recommendations advanced. Opportunities for automatic fault detection and redundancy are presented. The smallest gyro and accelerometer modules are projected as requiring a volume of 26 in and 23.6 in , respectively. Corresponding power dissipation is projected as 5 watts and 2. 6 watts, respectively.
