【摘要】:GPS定位技術(shù)日趨成熟,已被廣泛應(yīng)用于各項工程建設(shè)中。本文通過實例數(shù)據(jù)對GPS曲面擬合高程與水準(zhǔn)測量高程兩者的精度分析對比,可知控制網(wǎng)布設(shè)合理、觀測時間較好的情況下,GPS曲面擬合法得到的高程精度已達(dá)到四等水準(zhǔn)測量精度。在地形復(fù)雜、水準(zhǔn)測量困難的山區(qū),GPS曲面擬合高程可代替水準(zhǔn)測量。
[Abstract]:GPS positioning technology is becoming more and more mature and has been widely used in various projects. Through the analysis and comparison of the accuracy of GPS surface fitting elevation and leveling height, it is shown that the control network is reasonably arranged. When the observation time is good, the elevation accuracy obtained by GPS curved surface fitting method has reached the fourth grade leveling accuracy. GPS curved surface fitting elevation can replace leveling in mountainous area where topography is complex and leveling is difficult.
