(U) GAS-1Controlled Reception Pattern Antenna (CRPA)/AE

Description (U):

(U) GAS-1 is comprised of a Controlled Reception Pattern Antenna (CRPA) with the associated wiring harness, and the Antenna Electronics (AE). The GAS-1 is a Nondevelopmental Item Acquisition with modifications. The GAS-1 must meet the form, fit, function, and compatibility requirements of the existing AE-1/CRPA-2 configurations as defined in the GAS-1 Technical Performance Requirements Document (TPRD)/System Level Specification, and the Interface Control Document (ICD). GAS-1, as a system or as individual Line Replaceable Units (LRUs), must be functionally backward compatible with existing LRUs, interfaces, and support equipment such that present integration and support capabilities are completely unaffected. Due to the vast array of military platforms that must accommodate the GAS-1, the contractor may be required to modify or reconfigure the GAS-1 to meet the integration requirements of other host vehicles. In addition, it may be necessary to modify the GAS-1 to meet revised anti-jam user requirements which are currently being developed.
