GIANT Modernization Model Approach

Greg Gerten, Gary Green and Larry Gutman

Abstract:	The Global Positioning System (GPS) is a space-based radio navigation system that provides accurate, continuous, worldwide service to passive users. The GPS Interference And Navigation Tool (GIANT) is a one GPS-equipped platform versus many interference sources, constructive and repeatable simulation that is typically applied to determine the impact of navigation performance on operational effectiveness. GIANT runs on a PC, is US Government-owned, includes a user-friendly graphical interface for setup and execution, and runs much faster than real-time. GIANT is under formal GPS communitywide configuration control, has a growing user base, and is sponsored by the GPS Joint Program Office (SMC/CZ), Los Angeles Air Force Base California. Lt. Joseph Causey (SMC/CZE) is the Model Manager, and more information can be obtained from the GIANT website: http://giant.veridian.com. The release of Version 1.1.2 (V1.1.2) occurred in August 2000, and V2.0.0 is planned for a February 2001 release. This paper will detail the current V2.0.0 efforts for multiple frequencies and codes, M-code, Jammer-to-Signal Ratio (J/S), acquisition and variable User-Equivalent-Range-Error (UERE).
