Abstract:	CAST is involved in the development of navigation software to integrate the Rockwell-Collins aided Phase III GPS receiver with an Inertial Navigation System. The software receives inputs from the aided five-channel Phase III receiver and two Singer-Kearfott SNU-84-3 Inertial Navigation Systems. This paper discusses the features of the design that are of general interest and that will be most useful in similar applications. In addition, those aspects of the. aided five-channel Phase III GPS receiver's {referred to herein as the Phase III receiver) operation that are most limiting to the overall performance of an integrated system are described. Several simple modifications to the Phase III receiver processing are recommended that would greatly enhance the ability to achieve improved performance through further processing of the Phase III receiver data.
