| 内容記述 | OMEGA navigation system uses VLF radio wave which shows the remarkable stability and long distant coverage in its propagational characteristics. The stability of radio wave, however, is sometimes disturbed with strong solar flare produced from sunspot. This disturbance makes the phase of VLF wave rapid phase change (SPA) that introduce the error in fixing. The phenomena has been studying by many researchers, but these studies has focused on the higher frequencies in VLF band that means do not made in OMEGA range. This paper reveals that the propagation characteristics of SPA in OMEGA frequency, especially to analysis the relationship between the magnitude of SPA and solar zenith angle, solar X ray flare flux intensity on VLF propagation. The measurements were made both phase and field strength of OMEGA Hawaii and Reunion, 10.2kHz and 13.6kHz, during 1976 to 1981, at Kagoshima, Japan. The major conclusion can be described as follows: 1) Occurrence frequency of SPA is proportional to the sunspot number, 2) Magnitude of SPA depends on the distance of propagation path, X-ray radiation below 8A, and solar zenith angle, 3) SPA in OMEGA wave is not relates to the direction of propagation path. | |||||
