Problems solved by technology

The sensor on the UAV will burden the weight and energy consumption of the UAV, and the sensor can only play a role in the identification area. The situation of low altitude and low speed will reduce the efficiency of drone operation, and even lead to recovery failure

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 2 As shown, the invention provides a device for realizing the dynamic recovery of an auxiliary fixed-wing UAV, including a UAV ground station, a differential satellite reference station and a landing platform. Existing dynamic recovery devices for UAVs, such as figure 1 As shown, the landing platform and the UAV are connected by sensor signals, so only when the UAV enters the recognition range of the sensor can the guided landing recovery be carried out. The present invention improves on the basis of the existing recovery method. Specifically, a differential satellite receiver and a digital transmission station are installed on the landing platform, and the correction amount and the GNSS signal of the differential satellite reference station are received, and the differential positioning is used to calculate the The accurate p...

Abstract

The invention discloses an apparatus for realizing auxiliary fixed-wing UAV dynamic recovery and a realizing method thereof belonging to the technical field of UAV recovery. According to the invention, a differential satellite receiver, a satellite reception antenna, a data transmission radio station and a data transmission radio station antenna are installed on a landing platform. The data transmission radio station receives differential correction emitted by a differential satellite reference station, calculates the accurate position of the landing platform with aid of the differential satellite receiver and sends the accurate position of the landing platform to a UAV ground station and an UAV again through the data transmission radio station. According to the invention, differential satellite positioning technology is adopted; when the UAV is relatively distant from the landing platform, landing attitude correction of the UAV can be realized; and a meaning of raising the UAV navigation precision and endurance time is realized. Through the apparatus and method of the invention, two recovery modes of the UAV can be realized.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and relates to a device for realizing the dynamic recovery of a fixed-wing unmanned aerial vehicle assisted by differential satellite positioning technology. Background technique [0002] The recovery of drones is very important in flight, and it is also one of the key points and difficulties. It is more prone to problems than other flight modes. At this stage, most fixed-wing aircraft use the landing gear to roll and land for recovery. This method has higher requirements on the site. , with the improvement of technology, new recycling methods emerge in endlessly. Recycling is based on the principles of simplicity, low cost, light weight, and small size. It can be recycled from any point within the working range, suitable for long-term storage, insensitive to damage, and improves the cost-effectiveness ratio (cost / efficiency) of drones. The world UAVs are more and more likely to...
