This paper introduces the repetition measurement of geodetic monitoring net of Huang Lashi land slide by GPS. 介紹運用GPS復測黃臘石滑坡大地形變網，并將其測量成果與常規(guī)方法作精度比較。
Line repetition measurement is on important link in transmission line construction, which directs the localization of poles and towers, directionality and linearity of lines. 線路復測為線路桿塔的定位、線路的方向性、直線性等提供依據，是輸電線路施工的重要環(huán)節(jié)。
The influence of the selection of observation time on baseline accuracy is studied, for appropriate arrangement for repetition measurement GPS network and raising work efficiency. 研究觀測時間的選擇對基線精度的影響，對合理安排GPS網復測和提高工作效率有一定的借鑒意義。 http://dict.cnki.net
