Abstract

The invention discloses an unmanned aerial vehicle control system which comprises a radio frequency management unit, including a receiving module for receiving signals, an enhancement module for collecting signals of the receiving module and a processing module, the processing module receives the signals from the enhancement module and the enhancement module comprises a first coupler and a secondcoupler. The receiving module receives signals of different frequency bands, and the first coupler and the second coupler carry out enhancement processing on the signals. Compared with the prior art,the radio frequency management unit can search two frequency bands at the same time, more signals can be received, the accuracy is improved, and the impedance of the receiving module is adjusted through filtering, signal amplifying, signal integrating and receiving module impedance adjusting, according to the invention, the filter filters out unnecessary clutters, the performance of the receivingmodule can be effectively enhanced, only no more than 20 satellites can be searched under the conventional condition of the existing single-frequency GPS on the market at present, by use of the system, more than 40 satellites can be searched in each frequency band, and the highest centimeter-level precision can be achieved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle control, in particular to an unmanned aerial vehicle control system. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle" ("UAV"), is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAVs are more and more widely used in civil and military fields, and the development of UAVs has also attracted the attention of various countries. The role of track tracking and control in the flight process of UAVs is particularly important, which can further improve the quality of UAVs. The dynamic performance of the man-machine provides a strong guarantee for the UAV to complete various tasks safely and efficiently. High-precision GPS measurement must use carrier phase observations. RTK positioning technology is a real-time dynamic positioning technology based on carrier phase observations. It can provide real-time thr...
