Abstract:
A tilt measurement method for an RTK measuring receiver includes the following steps: step Si: fixing the bottom of a centering rod and performing a measurement after an inclination and shake; step S 2:  obtaining a measurement point sequence, a measurement point tilt sequence, a length of the centering rod, and a height of an antenna phase center based on the measurement; step S 3:  obtaining a positioning quality threshold and a geodetic coordinate of the to-be-measured point based on values obtained from the measurement; and step S 4:  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.

Claim (Index 16):
The tilt measurement method for the RTK measuring receiver according to  claim 10 , wherein in the step of S3b, assuming that an observation tilt angle of the observation point is \u201cdi, the second type of observation equation is expressed by an equation (11):\n Li =N o  H i  (11) wherein 74.L i cosgi , so an equation (12) can be obtained after operating based on the equation (11): v =v H  (H i  L i cosO i H o ) (12) combining the equation (8) and the equation (12) to establish an error equation set (13): V = BX - W , P \ue89e \n \ue89e wherein \ue89e \ue89e X = [ V N V E V H ] ; \ue89e \n \ue89e B = [ N 0 - N 1 L 1 0 E 0 - E 1 L 1 0 H 0 - H 1 L 1 0 N 0 - N 2 L 2 0 E 0 - E 2 L 2 0 H 0 - H 2 L 2 0 \u2026 N 0 - N n L n 0 E 0 - E n L n 0 H 0 - H n L n 0 0 0 1 0 0 1 \u2026 0 0 1 ] ; \ue89e \n \ue89e W = [ L 1 - L 1 0 L 2 - L 2 0 \u2026 L n - L n 0 H 1 - L 1 \ue89e cos \ue89e \ue89e \u03b8 1 - H 0 H 2 - L 2 \ue89e cos \ue89e \ue89e \u03b8 2 - H 0 \u2026 H n - L n \ue89e cos \ue89e \ue89e \u03b8 n - H 0 ] ; ( 13 ) P is a weight matrix, wherein P is set according to an accuracy of the observation values, if information of the accuracy of the observation values is not available, P is set as a unit matrix.
