    Abstract: 本論文發展利用福爾摩沙衛星三號酬載之小型電離層光度計(Tiny Ionospheric Photometer, TIP)和GPS衛星掩星觀測實驗(GPS Occultation Experiment, GOX)建立全星載電離層斷層掃描。GOX的掩星觀測資料能提供垂直方向的電離層電子濃度結構。而TIP於夜晚進行高光感度 OI 136.5nm 大氣暉光觀測,由於其觀測視角非常的小(3.8°),因此能精確的觀測水平方向的電離層電子濃度梯度。研究顯示結合此兩種觀測資料可大幅提高反演結果的準確度。結合此兩觀測資料最大優點為,可於全球各地(尤其可突破海洋和無人沙漠地區等人煙稀少區域)進行星載電離層斷層掃描。 This study develops a space-space tomography by means of data recorded by tiny ionospheric photometer (TIP) and GPS occultation experiment (GOX) onboard FORMOSAT-3/COSMIC. TIP and GOX record the OI 135.6 nm airglow intensities and the occultation total electron content (TEC) for the nighttime ionosphere, respectively. Due to its very high sensitivity ~600 counts/Rayleigh and rather narrow nadir pointing 3.8° circular field-of-view, the TIP provides accurate characteristics of ionospheric electron density gradients in the horizontal direction. Meanwhile, the GOX data gives the information in the vertical direction. It can be seen that the two observations could yield a better result, which shows the space-space tomography an alternatively way to reconstruct the ionosphere all over the world, especially on the ocean and desert areas.
