Systematic Design of Modular Estimators for Aircraft Navigation

Abstract

Recent hardware advances have made it practical to build relatively sophisticated data preprocessors into sensor packages. To take full advantage of these developments, a navigation system could use an estimation architecture with data preprocessors located in the sensor packages and a data coordinator located with the information user. This type of data processor, termed herein a 'modular estimator,' has a structure which makes possible: parallel computation, modular design, interface standardization, system reliability improvement, and channel capacity reduction. This report presents a systematic procedure for designing modular estimators and applies the procedure to a simple example. The mathematical foundations for this procedure, including new rate-distortion theory results, are presented in Appendix A.
