Analysis of In-Flight Omega Data (Data taken 26 January - 7 February 1969 are Compared with Predicted Values for Paths from Hawaii to San Diego, Samoa, and Wake; and from Samoa and Wake to Hawaii).

Abstract

Measured amplitude data for 10.2 and 13.6 kHz were compared with the corresponding theoretical amplitudes along these paths. Various ionospheric profiles were used in the theoretical calculations in order to find an amplitude curve which fit the data. The Hawaii to San Diego path was so homogeneous that midpath values for ionospheric parameters were used along the entire path. Theory corresponded with data. Both similarities and differences were found among the Hawaii to Wake and Wake to Hawaii data. The Hawaii to Samoa and Samoa to Hawaii paths were characterized by rapid oscillation of amplitude in the region near the geomagnetic equator. Further investigation is recommended. (Author)
