PRELIMINARY DESIGN OF A REDUNDANT STRAPPED DOWN INERTIAL NAVIGATION UNIT USING TWO-DEGREE-OF-FREEDOM TUNED-GIMBAL GYROSCOPES

摘要

This redundant strapdown INS preliminary design study demonstrates the practicality of a skewed sensor system configuration by means of: (1) devising a practical system mechanization utilizing proven strapdown instruments, (2) thoroughly analyzing the skewed sensor redundancy management concept to determine optimum geometry, data processing requirements, and realistic reliability estimates, and (3) implementing the redundant computers into a low-cost, maintainable configuration.
