TILT MEASUREMENT METHOD FOR RTK MEASURING RECEIVER

摘要

Atilt measurement method for an RTK measuring receiver includes the following steps: step S1: fixing the bottom of a centering rod and performing a measurement after an inclination and shake; step S2: obtaining a measurement point sequence, a measurement point tilt sequence, a length of a measuring rod, and a height of an antenna phase center based on the measurement; step S3: obtaining a positioning quality threshold and a geodetic coordinate of the to-be-measured point based on values obtained from the measurement; and step S4: determining whether the positioning quality threshold meets a requirement or not to decide whether to finish the measurement or not. In the method, the position of a to-be-measured point is calculated according to the position and the tilt angle of the antenna phase center of the receiver, and the length of the centering rod etc. during multiple tilt measurements. For a centimeter-level RTK, the position calculation with centimeter-level accuracy can be achieved when the amount of observation values is sufficient.
