  3. ( 3 ) the optimized strategy analysis on retrieval of gps water vapor the optimized strategy analysis on retrieval of gps water vapor has been carried out under different data processing schemes by using gps observation. the parameters selection problem has been resolved in gps water vapor retrieval process such as the optimum number of adopted igs stations, the relation between single station processing and united station processing, network layout, cut - off angle, zenith delay parameter, period, knot position and so on

    （ 3 ） gps水汽反演優化策略分析利用gps觀測數據，使用多種數據處理方案，進行gps水汽反演優化策略分析，初步解決了進行gps水汽反演中引入igs站的最佳個數、單站解算和聯合解算的關系、網路布局、截止高度角、天頂延遲參數、時段長度、節點位置等選擇問題。
  4. The paper has made detailed observation by the existing apparatus and the field observation stations. based on the image and the vector database of the yutian oasis, the study has obtained the precise coordinates of investigation points by gps technique, and overlapped them with the images. after classifying the images with the maximum likelihood supervised classification method, we import the result into cis software, and analyze the yutian oasis changes about land cover " s quantity, quality and spatial position from 1976 to 2001

    本文利用現有儀器設備和野外觀測網站進行詳細觀測，在建立於田綠洲圖像庫和矢量數據庫的基礎上，運用gps技術取得野外考察樣點的精確坐標並與研究區各時期影像疊加，對影像進行了最大似然法監督分類，並將分類結果轉入gis軟體處理，全面分析了1976年至2001年該綠洲的土地覆蓋類型數量、質量與空間上的變化。
  5. The third chapter involves some problems on attitude determination and integrity ambiguity resolving. using three formation flying satellites for an earth observation as an example, the forth chapter contains some problems about determination of inter - satellite position, attitude and time, by using high precise pseudo - ranging observation onboard pseudolites. the problems are the selecting of coordinate system and independent state parameters, the setting of observation equations, and the conversion of constellation ' s states

    第四章以三星編隊星座為例，討論利用擴展的高精度星間偽距觀測進行星間相對位置、姿態和時間參數確定的一些問題，包括：坐標系、獨立參數的選取、觀測方程的建立和星座狀態的轉換等。
