Abstract

A novel method is discussed to simplify the calculation and analysis procedure of PWCS (piece-wise constant system) Observability Analysis Theory. By research of simplified and general expressions of observable variables, this method can be easily used to identify the relationships between observability variations and different time segments. A new transformed stripped observability matrix (TSOM) or a simplified TSOM is introduced which simplifies the analysis. The simplified observability analysis is presented as a step-by-step procedure. The use of the new method is illustrated by considering on-line calibration of a dynamic tuned gyro (DTG) strap-down inertial navigation system (SINS) on moving base. Simulation results validate the new approach.
