Abstract : This report documents a study of the types and amounts of errors inherent in the various instrumentation systems used for close-in and far-field dynamic flight tests for the Microwave Landing System (MLS) Development Program Phase II, at the two test sites and the four runways utilized, one for each contractor MLS. Analysis of Phase II flight test data depended on comparison of MLS azimuth, elevation and range functions with the same functions generated by ground tracker data, the difference being the error of the MLS functions if the error in the tracker functions is smaller by at least an order of magnitude. This study not only summarizes the results of hardware calibrations, data processing techniques and tracker error studies made during Phase II to define and reduce tracker errors, but projects the impact of remaining tracker error on MLS Phase Ii test results.
