Abstract

The embodiment of the invention provides a positioning method, device and equipment. According to the positioning method, device and equipment, positioning parameters of a positioning signal are acquired. The positioning signal comprises a first positioning signal and a second positioning signal, wherein the first positioning signal serves as communication signal between an auxiliary positioning unmanned aerial vehicle and a ground base station; the second positioning signal serves as communication signal between the auxiliary positioning unmanned aerial vehicle and points to be positioned, and the number of the auxiliary positioning unmanned aerial vehicles is no less than three. The position coordinate of the points to be determined can be determined based on the positioning parameters of each second positioning signal and the position coordinate of each auxiliary positioning unmanned aerial vehicle. In the positioning process, an auxiliary positioning unmanned aerial vehicle which is relatively close in distance and has a certain height is used as an auxiliary positioning device; good sight distance is provided, the strength of the positioning signals is guaranteed; the blockingof the barriers can be avoided, and the stability and the accuracy of positioning are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of positioning, and more specifically, to a positioning method, device, and equipment. Background technique [0002] Location information plays an increasingly important role in today's intelligent society, and the demand for high-precision location information will become more urgent in the future. Location information is used in more and more services, whether in civil or military applications, location information plays an important basic role. Typical application scenarios include guidance and anti-missile, formation control, emergency rescue, map navigation, smart city, logistics tracking, etc. [0003] At present, most of the commercial positioning, navigation, and timing services in outdoor scenarios are provided by satellites. However, this kind of non-cooperative network with a single structure has limited accuracy and is easily affected by some non-ideal factors, such as non...
