POSITION MEASUREMENT STANDARD EVALUATION

The objectives of the Position Measurement Standard Program were to collect navigation data from three DME receivers and a low-frequency GLOBAL Navigation system, and evaluate their relative performance against a reference radar. Flight test data during June and July, 1974, established the following: triple DME was an order of magnitude more accurate than the GLOBAL system; triple DME accuracy was repeatable, smooth over all flight regions, and insensitive to initial condition, whereas GLOBAL system accuracy varied from run to run, exhibited large random errors and quantum 'jumps', and was dependent upon error nulling procedures prior to system initialization.
