Abstract:	This paper describes the development of an integrity monitoring capability for the Joint Precision Approach and Landing System (JPALS). A subsystem known as the JPALS Land-based Integrity Monitor (JLIM) attempts to detect and isolate faults associated with GPS satellites, the signal in space, or the ground-based receivers used to generate differential corrections. In this paper we detail the design of a test platform for JLIM. This test platform enables the comparison of various integrity monitoring architectures and algorithms. In particular, the test platform provides the means to compare several integrity monitoring options specific to the JPALS implementation. These design choices include monitoring architectures for dual-frequency measurements, executive monitoring algorithms for availability maximization, and threshold-establishment methods for JLIM deployment in real-world scenarios.
