Correction for Centring of Long Deflection Distance in GPS Surveying
摘要
Abstract
Specifications for GPS surveys presents the correction formula of centring in GPS surveying, which is based on the short deflection distance. In the paper,we take into account the earth curve error and other factors, get the accurate correction formula of centring as a result, which is fit for the long deflection distance. Respectively with the two formulas, in addition to the traverse network adjustment, many groups of experimental data were calculated. The conclusion is drawn that when the deflection distance is long, the precision with the formula presented in the paper is much higher than in the criterion, equivalent with that from the traverse network adjustment only if the deflection distance is not longer than 1500 meters.关键词
