Problems solved by technology

[0004] However, in actual situations, there are obstacles between the sending end and the receiving end, such as tall buildings, trees, etc., so the signal is affected by path fading during the propagation process, which makes the signal strength of the receiving end decrease.

Abstract

The invention relates to an auxiliary positioning method for an unmanned aerial vehicle. The method comprises the following steps: obtaining a receiving signal with noise through a signal intensity model; inputting the receiving signal with noise into a filter for filtering so as to eliminate shadow noise in the receiving signal; carrying out iterative processing on the receiving signal subjected to shadow noise elimination through a cost model so as to obtain a path fading factor and a distance between the transmitting end and the receiving end; and positioning the user according to the path fading factor and the distance between the transmitting end and the receiving end. According to the method, the influence of the shadow effect on the signal strength can be considered, and the acquisition precision of the path fading factor is improved, so that the positioning precision of the user meets the actual application requirement.

Description

technical field [0001] The present application relates to the field of UAV navigation and positioning technology, in particular to a UAV-assisted positioning method, system, storage medium and terminal equipment. Background technique [0002] With the continuous development of information technology and communication technology, drones are widely used in industry and science, such as weather monitoring, communication, and detection through drones. Due to its high mobility, low cost, and easy deployment, UAVs are also used more in positioning. [0003] In recent years, in order to improve the positioning accuracy of mobile users in non-line-of-sight situations, RSS positioning has been applied accordingly. RSS positioning is a positioning method that calculates the distance between the sending end and the receiving end based on the strength of the signal received by the receiving end. [0004] However, in actual situations, there are obstacles between the sending end and th...
