Abstract

The invention discloses an unmanned aerial vehicle GNSS reference station data transmission and control method, device and system. The system comprises an unmanned aerial vehicle GNSS reference station data transmission and control device, a GNSS board card, a networking communication device and a data acquisition and recording device; the unmanned aerial vehicle GNSS reference station data transmission and control device comprises a command interaction server, a differential forwarding server and an FTP file server that are connected with a terminal device. According to the invention, the three data links of differential data, the host information / control interaction, and the file operation are integrated, the terminal device can access different port servers to obtain the corresponding data, and the direct interaction can be carried out through the corresponding ports to control the reference station equipment. According to the invention, the reference station data flow is integratedinto one data link, so that complex and diversified communication interaction is reduced, and only from one communication link, a plurality of data can be acquired, the control of the host is realized, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of GNSS positioning equipment in the surveying and mapping industry, in particular to a data transmission and control method, device and system of a UAV GNSS reference station. Background technique [0002] With the miniaturization of GNSS antennas, the use of airborne GNSS receiver equipment is becoming more and more mature. In terms of UAV space positioning technology, real-time RTK (Real-time kinematic, carrier phase difference technology) and post-processing PPK (PostProcessing Kinematic, dynamic measurement data post-processing technology) are the two most mature technology applications. Ground reference stations are an important part of both technologies. [0003] The real-time RTK positioning of the airborne GNSS receiver needs to receive the differential data sent by the ground reference station through the data transmission module for real-time calculation to obtain the RTK solution. RTK technolog...
