no. 1 approach

[0035] see figure 1 and combine figure 2 , the first embodiment of the method for judging whether the RTK result is correct in the present invention comprises the following steps:

[0036] S1. The rover is equipped with a master antenna M and a slave antenna S, and obtains the baseline in the RTK results between the master antenna and the slave antenna as the first baseline, the baseline of the master antenna RTK results as the second baseline, and the slave antenna RTK results in the baseline baseline as the third baseline.

[0037] In this step, the rover is, for example, an unmanned car, and a master antenna and a slave antenna are installed on the roof of the car. The mobile station can also be an unmanned aerial vehicle, and the unmanned aerial vehicle is equipped with a master antenna and a slave antenna. like figure 2 As shown, the baseline (first baseline) in the RTK results between the master antenna and the slave antenna is shown as B1, the baseline (second bas...

Abstract

The invention discloses a method for judging correctness of an RTK result, an OEM board card, a receiver and a storage medium. The method comprises the following steps: obtaining RTK results of each antenna and RTK results between the antennas, and obtaining baselines of the respective RTK results from the RTK results of any two adjacent antennas and the RTK results between the two antennas; judging whether baselines in the three RTK results form a closed ring or not, resetting an RTK algorithm for obtaining the RTK results or generating a prompt signal if the baselines in the three RTK results cannot form the closed ring, and sending at least one RTK result outwards if the baselines in the three RTK results can form the closed ring. The method for judging correctness of an RTK result canaccurately and quickly judge whether the RTK result is correct or not.

Description

technical field [0001] The invention relates to the technical field of high-precision navigation, in particular to a method for judging whether the RTK result is correct, an OEM board, a receiver with the OEM board and a storage medium. Background technique [0002] RTK (Real-time kinematic, real-time dynamic) technology can obtain centimeter-level positioning accuracy in real time in the field, and is widely used in unmanned driving, precision agriculture, deformation monitoring, mechanical control, and drones. [0003] However, RTK technology needs to receive satellite signals to achieve positioning. Therefore, in actual use, multi-path and signal quality received by antennas may cause RTK results to be incorrect. In the process of urban canyons, bridges, tunnels and other places, the quality of the received satellite signal may be poor due to multi-path and occlusion, thus causing errors in RTK results. An error in the RTK result will make the technology lose its advanta...
