The invention provides an RTK measuring receiver tilt measurement method. The method comprises the following steps that 1, the bottom of a centering rod is fixed, tilting and shaking are conducted, and then measurement is conducted; 2, on the basis of the above-mentioned measurement, a measurement point sequence, a measurement point tilted sequence, a measuring rod length and an antenna phase center height are obtained; 3, on the basis of a numerical value obtained through measurement, a positioning quality target and geodetic coordinates of the points to be measured are obtained; 4, whether the positioning quality target meets the requirement or not is judged, weather measurement is finished or not is determined. According to the method, the positions of the points to be measured are calculated according to the positions and inclination angles of the receiver antenna phase center, the centering rod length and the like when a certain number of tilt measurements are conducted, and for centimetre-sized RTK, when the number of observed values is enough, the centimetre-sized position calculation precision can be obtained.
