Abstract: A technique is presented whereby the information from a star-tracker is used to provide an optimum stellar-inertial system. It represents practical application of optimum linear estimation and control theory. Simulation runs are included to show the relative accuracy achieved by using the stellar information to "reset" the inertial system. The information from a pair of stars is prefiltered to obtain an effective discrete reference for comparison with the basic inertial system. The essential novelty afforded by the technique is that random noise in both the system and the reference information is taken into consideration. The net result shows theoretically a marked improvement over more conventional uses of stellar information.
