Experiences Implementing the Supplemental MOPS Off-Line Test Procedures

William R. Michalson and Christine Easton

Abstract:	This paper describes the design and implementation of a simulation testbed conforming to the requirements for off-line testing of RAIM algorithms, as detailed in the RTCA Supplemental MOPS[ 11. This simulator is useful for two primary reasons. First, it allows gaining insight into the details associated with implementing and performing the tests specified in the Supplemental MOPS. Second, it provides a research tool which allows us to easily implement and evaluate many different RAIM algorithms in a common test environment. Many of the details associated with designing and implementing the simulator are prcsentcd. During the design process we found several places where additional information in the MOPS would help ensure that the intentions of the authors of the MOPS are followed. In cases where additional information would have been useful, the assumptions used to implement the simulator are provided. In making such design decisions we biased our interpretations by what we believe the authors of the MOPS intended. The paper concludes by presenting the results obtained from running the off-line test on a recently proposed RAIM algorithm.
