摘要(中)

比較結果顯示，由兩系統獲得的F2層的臨界頻率(foF2)和電子密度隨高度分佈的一致性都相當優異，故對於GPS/MET系統得到的電離層資訊的可信度將大大的提升。

摘要(英)

The Global Position System/Meteorology (GPS/MET) was to use a low Earth orbiting satellite to receive dual-channel Global Position System (GPS) carrier phase signals and sounding the Earth’’s atmosphere and ionosphere by radio occultation techniques. Under the assumption of local spherical symmetry, the phase data have been processed through the computation of the bending angel or the total electron content to yield the profiles of ionospheric electron density via the Abel integral inversion. To approach a near-time process, electron density profiles can be derived through computation of the total electron content assuming straight-line propagation. The computation of total electron content was be used in this thesis. In order to assess the accuracy of the GPS/MET ionospheric electron density retrievals, the retrieved electron density profiles from GPS/MET TEC observations have been compared with the ionogram inversion results derived from DPS operated by the National Central University (the Chung-Li digisonde; 24.6°N, 121.0°E). The autoscaling system and true-height inversion processed the ionogram to yield the inversion results. The data were used from the observations of the two systems in 1996 in this thesis.
The comparison results show good agreement for both of the derived electron density profiles and the F2-layer critical frequency (foF2). The reliance of the ionospheric information form GPS/MET system raised greatly.
