Abstract

The invention discloses a method, a device and a system for data transmission and control of an unmanned aerial vehicle GNSS reference station. The system includes a data transmission and control device of an unmanned aerial vehicle GNSS reference station, a GNSS board card, a network communication device, and a data acquisition and recording device; The data transmission and control device of the GNSS reference station includes a command interaction server, a differential forwarding server and an FTP file server respectively connected with the terminal equipment. The present invention integrates three data links of differential data, host information / control interaction and file operation, terminal equipment can access different port servers to obtain corresponding data, and can also directly interact through corresponding ports to control reference station equipment. The embodiment of the present invention integrates the data stream of the base station into one data link, reduces complex and diverse communication interactions, and can obtain various data from only one communication link, realize host control, and improve operation efficiency.

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 method, device and system for data transmission and control of a GNSS reference station of an unmanned aerial vehicle. Background technique [0002] With the miniaturization of GNSS antennas, the use of airborne GNSS receiver equipment is becoming more and more mature. In UAV spatial 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 s...
