GPS Application Enhancement with Block IIF Civilian Dual Frequency

R. Kumar, P. Munjal and S. Hwang

Abstract:	The GPS Joint Program Office (JPO) is procuring GPS follow-on Block IIF satellites. The ability to transmit civilian dual frequency GPS signals on Block IIF satellites is a preplanned option that the JPO may exercise in conjunction with the United States Department of Transportation (DOT). The DOT is in the process of funding for the civilian dual frequency on the Block IIF GPS satellites. This paper describes various civil applications data measurement and processing schemes involving wide area DGPS, local area DGPS, real-time kinematics, and post- processing situations. The resulting enhancement due to the dual frequency in these scenarios has been evaluated in terms of accuracy and availability. These requirements have been briefly stated for several civilian GPS applications, such as Intelligent Vehicle Highway Systems (IVHS), marine navigation, and land transportation. Also presented are various GPS data measurement and processing techniques currently employed in these applications. Enhancements in the performance of these techniques due to dual frequency as against single frequency performance are presented.
