Estimating Conservative Error Bounds for INS Output Errors

Demoz Gebre-Egziabher

Abstract:	This paper examines the problem of estimating conservative error bounds of inertial navigation systems when they are used as part of an integrated navigation system designed around a low cost inertial measurement unit (automotive/commerical grade). This is done by recasting the inertial navigation error equations for low cost sensors in a form which allows proving that the time update equations can be statistically overbounded. The resulting overbounds, however, are shown to be overly conservative.
