一种改善RTK测量精度的新方法

摘要

提出一种通过测量球面坐标,拟合球心间接求取测量点坐标的新方法.通过实例验证,RTK球心拟合测量点法的平面精度和GPS静态观测相比,误差不超过厘米级,可以避免对中杆倾斜引起的测量误差,而且在一定程度上提高了RTK平面观测精度.%On the basis of the analysis of impect factors of surveying accuracy of RTK, focusing on analyzing measurement error caused by human factor I. E. Centering rod tilt, a new method which is by surveying spherical coordinates and fitting sphere centre coordinates to calculate measured point coordinates is put forward. Through examples, compared with GPS static observation, the error of RTK method is of less than cm level. This not only proves that RTK fitting sphere centre can avoid the error caused by centering rod tilt, but also improves RTK plane accuracy to a certain extent.
