Open-Loop Inertial Measurement Unit Error Analysis Monte Carlo and Root- Sum-Square

Abstract

This report defines closed-loop and open-loop error analysis techniques commonly used in the aerospace industry. Equations for modeling inertial platform error sources (including accelerometers, gyros, and alignments) are also given. Correlation of data obtained by Monte Carlo techniques is compared to data generated by root-sum-square methods and shown for a typical ballistic missile. Finally, validation of the Open-Loop Error Analysis Program is verified by comparison to independent error analysis program (GEAP), and to an error covariance program. In each of these cases the results have proven comparable serving to validate the results.
