Error Source Recovery from INS Test Flight Data.

Abstract

The CIRIS system at Holloman Air Force Base provides a highly precise reference for the flight testing of navigation systems. This report explores the recovery of the significant sources of error of an inertial navigation system under test through optimal filter techniques, using CIRIS data as reference information. A Kalman filter modelling all the significant sources of error for the test INS and the CIRIS INS and precision ranging system, is executed over a set of selected flight test profiles. The estimation of individual sources of error is shown to be inhibited by correlation of the contributions of error sources to the measured quantities. Highly correlated error sources are then lumped into linear combinations, and the reduced error model Kalman filter is executed over the test profiles.
