Abstract: This article compares the use of P-code and C/A-code GPS receivers on test and training ranges. The requirements on many ranges for operation under conditions of jamming preclude the use of C/A-code receivers because of their relatively low jamming immunity as compared with P-code receivers. Also, C/A-code receivers present some problems when used with pseudolites on ranges. The cost of P-code receivers is customarily much higher than that of C/A-code receivers. However, most of this cost difference is caused by factors other than P-code, particularly the parts screening specifications applied to military programs.
