Abstract

The invention provides a method for verifying the RTK tilting compensation measurement precision. The method comprises the following steps: acquiring a center coordinate, acquiring compensation measurement points, calculating the offsets and the height difference of the measurement points in real time, recording and displaying the offsets and the height difference, carrying out automatic statistic processing on the maximum error and the maximum error of the compensation measurement points near to one point location, and verifying that whether the RTK tilting compensation measurement precision meets designed precision requirements or not. The method reduces the requirements of operating personnel to the lowest level, can be used to detect the tilting compensation measurement precision of an RTK device, can be built in measurement software to judge whether tilting compensation measurement data of a user is useful or not in real time, and provides an available method for satisfactory use of an RTK tilting compensation measurement mode.

Description

technical field [0001] The invention relates to the field of surveying and mapping, in particular to a method for verifying measurement accuracy of RTK tilt compensation. Background technique [0002] With the rapid development of satellite positioning technology, people's demand for fast and high-precision location information is also increasing. At present, the most widely used high-precision positioning technology is RTK (real-time dynamic positioning: Real-Time Kinematic). The key to RTK technology is the use of carrier phase observations of GPS and the use of observation errors between reference stations and mobile stations. Spatial correlation removes most of the errors in the observation data of the mobile station by means of difference, so as to achieve high-precision (decimeter or even centimeter level) positioning. In the RTK operation mode, the base station transmits its observation value and station coordinate information to the rover through the data link. The...
