　　本研究是運用二基地站接收機的載波相位，建立不同時間及不同衛星觀測量之單點差分測量絕對定位、三差測量相對定位（Tripple Difference of Carrier Phase）及差分測量虛擬距離相對定位聯立方程式，並將第個衛星的鐘差誤差及其對應的電離層傳播延遲誤差等，以二至三階多項式近似法展開，運用最小二次方誤差（Least Squared Error）計算出接收機的位置。此種多項式展開的方法，目前在國內尚待開發研究。目前所做的探討是衛星模擬器的標準訊號，以一公里內所做的靜態分析，研究結果其精確度在公分級以下的程度，所以對需要較高精度的定位而言，這是非常有效的方法。

　　In this research both the absolute and relative positioning method based on carrier phase are studied. The relative Positing are obtarned by using the carrier phase tripple difference of the two receivers for different times and different satellites, in which the satellite orbit errors and the inospheric errors are modelled by the tirsf or second order power series approximation, then solved by the lest-square-error method. This methodology was not studied in the past. The advantage of which is to raise the accuracy to centi-meter level, which can be used for the higher accuracy vehicle guidance system.
