Results of a Differential Omega experiment

An experiment was performed to examine the utility of Differential Omega navigation for general aviation in Alaska and Northwest Canada, with emphasis on operational issues. The performance of a prototype Differential Omega system is evaluated for performance parameters such as maximum range of the data link, mean and variance of navigation error, and range decorrelation error. Mean error was observed to be about 0.5 NM, and the standard deviation error was about 0.25 NM. Ground tests yielded results that were consistent with results of earlier experiments, and random errors agreed well with the minimum range results.
