Problems solved by technology

This puts more pressure on the equipment installation and power supply on the UAV, which is already relatively tight, and also increases the weight of the body
Especially for small and medium-sized UAVs, due to their small body, the antennas of the airborne DGPS data transmission station and the measurement and control station cannot be installed too far apart, and it is easy to cause mutual interference between the two

Embodiment Construction

[0043] The present invention will be further described below in conjunction with specific examples.

[0044] As shown in FIG. 2 , it is a schematic diagram of the technical solution of the present invention to transmit DGPS data in real time using the UAV measurement and control link. The transmission process of DGPS data in the present invention involves the airborne DGPS receiver 2, the airborne measurement and control station 3, the airborne computer 5, the ground measurement and control station 8, the ground DGPS reference station 9 and the ground station computer 11. First, the ground station computer 11 receives a frame of complete original DGPS data from the ground DGPS reference station 9 for processing; then, the processed data is sent to the UAV 6 by the ground measurement and control station 8; then, the UAV 6 The airborne measurement and control station 3 receives the radio wave signal sent by the ground measurement and control station 8 and processes it to obtain ...

Abstract

The invention discloses a method for real-time conveying the DGPS data with the observing and control chain circuit of the unmanned aerial vehicle, and the method is applied in the DGPS navigating of the unmanned aerial vehicle. The method comprises four steps as follows: DGPS data encoding, information complexing, information decomposing, and DGPS data frame decoding and processing. At the state of no increasing wireless data digital transmission station, the method has the effects of realizing the real-time wireless conveying between the earth DGPS reference station and the airborne DGPS receiver, saving the earth and airborne wireless digital transmission station, reducing the system cost, reducing the supplying pressure of the airborne electric power source and the weight of the vehicle, simplifying the installing problem of the airborne equipment, and eliminating the mutual interference problem which is difficult to eliminate in the existing technique and between the airborne DGPS digital transmission station and the observing and controlling station.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle navigation and communication, and in particular relates to a method for real-time transmission of DGPS data using an unmanned aerial vehicle measurement and control link. Background technique [0002] The UAV's measurement and control link is a two-way wireless data transmission channel composed of the UAV ground station and the UAV's two measurement and control transceiver stations, and its working distance is generally within 150km around the station. The measurement and control link of the UAV is mainly responsible for the uploading of ground remote control commands and the downlinking of on-board telemetry information. The data sent from the ground station to the UAV is called uplink data, and the data sent from the UAV to the ground station is called uplink data. downlink data. In order to ensure that the status of the UAV is monitored at all times and the UAV is controlled i...
