Abstract
Strapdown Inertial Systems are usually calibrated by means of very accurate and expensive turn tables. This high accuracy is not required if self-calibration techniques are employed which make proper use of less accurate reference information and the uncalibrated system output itself. Starting from fundamental calibration principles, such a technique is stepwise evaluated for geometric parameters. The steps cover the general three-dimensional calibration model, solvability considerations, the self-calibration of pairs and triplets of sensors-separate for accelerometers and single-degree-of-freedom gyroscopes, the essential determination of the rotation between them, and finally the combined self-calibration of both triplets. Pros and cons are discussed in view of the calibration principles.
