Abstract:

This thesis investigates the use of internally generated pseudo-range measurements to increase the sampling speed of a rate aided pointing and tracking system known as Aided Track. Six separate methods for generating pseudo-range measurements were developed for a two dimensional analysis of the problem. Five target scenarios of various complexity were used to test the systems. The results obtained indicate that the use of a pseudo-range measurement generated by using the internal estimate of range provided the best performance of all methods tested. This method demonstrated a definite improvement over the slower system when tracking highly maneuverable targets. Author
