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.
