The report describes a low cost system called VORLOC. This equipment was designed to be used in a manner similar to a standard localizer but operates on VOR frequencies with the standard VOR receiver and instrumentation. The results of tests conducted indicate that the quality of the course line of VORLOC is subject to its siting. The course line had an average 95 course path bend amplitude of .51 degrees, with extremes of .99 and .25 degrees. The maximum range was 31 miles at 2000 feet altitude and the stability of the course line was .57 degrees per standard deviation. It is concluded that VORLOC has potential as a low cost navigational aid capable of providing localizer-type guidance through a standard VOR receiver. Author
