オメガ航法システム利用実績についての調査結果-II

抄録

The accuracy of the OMEGA System is dependent upon the phase stability and predictability of phase variation. To get practical informations on coverage, reliability and accuracy of OMEGA System, Survey on the relative accuracy of the system was conducted in terms of selected pairs and their combination. These are the findings: 1. No pair combination gave relative error average of greater than 3.5 miles and its average was 2.5 miles. 2. In area 13, pairs AB, AE, AF, EF tend to show 5 to 9 cel in excess as an average and BE, BF, 2 to 4 cel in short. 3. Pair combination BE-BF, BE-EF, BF-EF showed relative error average of less than 2 miles. 4. These values change when data are specified with time; day, night or transient.
