Embodiment 1

[0145] Build a UAV near-field guidance system: build a UAV near-field guidance system, the master base station 111 and the slave base station 112 perform pairing and cross ranging;

[0146] UAV near-field sensing: the main base station 111 periodically wakes up the first sensing system 121, and after waking up, the first sensing system 121 actively sends a broadcast request message with ID to match with the drone;

[0147] UAV response: the UAV receives the broadcast request message with ID sent by the main base station 111 and performs matching. After the matching is successful, the airport perception system 22 responds to the request message and adds the UAV’s ID to the response message. Relevant information; if the match fails, no response will be given;

[0148] UAV positioning: the first perception system 121 receives the response message from the UAV, the master base station 111 wakes up all the slave base stations 112 on the ground, and the UWB onboard UWB positioning s...

Description

technical field [0001] The invention belongs to the application technical field of wireless communication, UAV wireless precise positioning, etc., and relates to a UAV near-field guidance system and method. Background technique [0002] The precise positioning of drones mainly relies on positioning technologies such as differential GPS and differential Beidou. The positioning accuracy is relatively high, but it is greatly affected by the environment. At the same time, due to network coverage and other factors, not every place can guarantee good positioning accuracy. On this basis, technologies such as visual recognition have been added, and the amount of data processed and the cost have increased significantly. [0003] The most typical defects in the existing system are mainly reflected in the following aspects: [0004] 1. Accurate positioning is greatly affected by the environment [0005] The existing precise positioning mainly relies on the differential system, which...
