Antenna control system, ground control terminal and method thereof

Abstract

The invention discloses an antenna control system, a ground control terminal and a control method thereof. The antenna control system comprises a controller, a positioning module, a signal transceiver, an antenna switching module, a tracking antenna and an omnidirectional antenna. Under control of the controller, a directional antenna realizes real-time tracking on an aircraft. The omnidirectionalantenna or the directional antenna is switched according to the real-time relative distance between the antenna control system and the aircraft; when the real-time relative distance is smaller than apreset threshold, the omnidirectional antenna is switched to be used; when the real-time relative distance is larger than the preset threshold, the directional antenna is switched to be used; the directional antenna is maneuverable, the large forward gain of the directional antenna can be fully exerted, the omnidirectional antenna and a tracking antenna are integrated, the communication stabilityat any distance and mutual interference resistance can be ensured, the expansion is strong, and the communication quality between the aircraft and the ground control terminal in the complete processof take-off, flight and landing can be ensured.

Description

technical field [0001] The invention relates to the technical field of aircraft antenna control, in particular to an antenna control system, a ground control terminal and a method thereof. Background technique [0002] A flight vehicle is a device that flies in the atmosphere or in the space outside the atmosphere (space). Those that fly in the atmosphere are called aircraft, such as balloons, airships, and airplanes. Unmanned aerial vehicle, referred to as "UAV", is a flying device controlled by radio remote control equipment and its own program. According to technical characteristics, UAVs can be divided into fixed-wing UAVs, unmanned helicopters, multi-rotor UAVs, and umbrella-wing UAVs. According to the application field, it can be divided into military drones and civilian drones. UAVs were originally used by the military, usually as reconnaissance and target aircraft. With the rapid development of drone technology, the intelligence of drones makes it widely used in c...

Problems solved by technology

Since the UAV uses GPS for positioning, if the GPS signal is not good, the GPS positioning result is prone to jump. value, this will cause the directional antenna to not be able to accurately radiate to the UAV, which may cause the ground control terminal to lose contact with the UAV, resulting in the inability to communicate with the UAV

In addition, this kind of following for the GPS jump value may damage the mechanical device and cause the failure of the antenna control system

At the same time, the compass is used for orientation sensing, but the compass is an inertial measurement unit, and it is prone to accumulated errors after long-term use, resulting in inaccurate positioning
