Abstract

The present invention provides a method for measuring the inclination of an RTK surveying receiver, comprising the following steps: Step S1: fix the bottom of the centering pole and tilt and shake it, and then measure; Step S2: Obtain the measurement point sequence and the measurement point inclination sequence based on the above measurement , the length of the measuring pole and the height of the antenna phase center; Step S3: obtain the positioning quality target and the geodetic coordinates of the point to be measured based on the measured value; Step S4: judge whether the positioning quality target meets the requirements, and decide whether to end the measurement. During tilt measurement, the position of the phase center of the receiver antenna, the tilt angle, and the length of the centering rod are used to calculate the position of the point to be measured. For centimeter-level RTK, when the number of observations is sufficient, centimeter-level position calculation accuracy can be obtained.

Description

technical field [0001] The invention relates to the technical field of RTK measurement, in particular to an inclination measurement method for an RTK measurement receiver. Background technique [0002] In RTK measurement, the centering rod of the rover needs to be placed vertically, and then the position coordinates of the points to be measured on the ground are obtained by calculating the position of the phase center of the GNSS receiver antenna and the distance from the phase center to the ground. However, in the actual measurement work, due to the influence of terrain conditions and the limitation of the instrument itself, many measurement points cannot be placed vertically and need to be tilted. As a result, the measurement process is cumbersome and the measurement error is large. Contents of the invention [0003] In order to solve the defects of the above-mentioned deficiencies, the present invention provides a method for measuring the inclination of an RTK measurin...
