Abstract:	A rational requirement must satisfy two conditions: (1) that there be a legitimate need, and (2) that compliance with requirements be realizable. This paper documents a study performed to define a rational burn-out requirement for GPS UE. Input to the study was MIL-STD-464, which defines a well-accepted Electro Magnetic Interference (EMI) threat. Antenna types appropriate for GPS use were defined, their gain as a function of frequency was measured, and the resultant power at the input of the UE was computed as a function of frequency. Requirement realization was assessed via a survey of Qualification, Test and Evaluation (QT&E) results for similar UE. This paper also documents the waiver evaluation process. A database of emitters for each MIL-STD-464 frequency sub- band was assembled. The process determines the safe distance and the distance loss to each emitter for any waiver-limited power at the UE.
