Abstract : Tests were conducted at the Federal Aviation Agency, (FAA), National Aviation Facilities Experimental Center, (NAFEC), to determine the distance measuring accuracy capabilities of several distance measuring systems. These systems were Tactical Air Navigation Equipment (TACAN), TACAN with a Jitter Eliminator ATTACHMENT (JEA), Nonstandard Measuring Equipment (NSME) and a Radar Identification Set AN/APX-6 beacon transponder equipment modified to provide distance measurement. Tests included measurement of the distance accuracy of each of the systems by comparison with the ranging information from Multi-Object Phase Tracking and Ranging System during flight test and laboratory measurements of the stability of the modified APX-6, TACAN and TACAN with JEA. The mean error and standard deviation was determined for each flight test run. A composite mean and standard deviation was then computed for each system. TACAN mean was 1077 feet and standard deviation was 513 feet. TACAN with JEA mean was 3927 to 4927 feet and standard was 454 feet. NSME mean was 901 feet and standard was 505 feet. APX-6 mean and standard deviation 311 feet and 372 feet. (Author)
