Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0049] see figure 1 , which shows the structure of a positioning device 10 provided by an embodiment of the present invention. The positioning device 10 may include: a transmitter 101, at least three receivers 102, and correspondingly connected to the at least three receivers. Phase detector 103, processor 104;

[0050] Specifically, the transmitter 101 can be placed on the position to be tested;

[0051] The at least three receivers 102 can be placed on known positions; preferably, any one of the at least three receivers 102 can be used as a reference point, and a coordinate system can be established with this reference point, so that know the specific location of other receivers 102;

[0052] The processor 104 may be connected to the phase detectors 103 respectively conne...

Abstract

The invention discloses a positioning method and device. The method comprises steps: positioning signals sent from a position to be detected are received in least three reception positions; first phase differences between the positioning signals in the at least three reception positions and reference signals in the at least three reception positions are determined; any two of the at least three first phase differences are subtracted, at least three second phase differences are obtained; distances of the at least three reception positions to the position to be detected are obtained according to the at least three second phase differences; the position to be detected is obtained according to the distances of the at least three reception positions to the position to be detected and the at least three reception positions.

Description

technical field [0001] The present invention relates to wireless positioning technology, in particular to a positioning method and equipment. Background technique [0002] The Global Positioning System (GPS, Global Positioning System) has been widely used, and the GPS can obtain the exact position of the observation point, and obtain the relative position of the two observation points according to the exact positions of the two observation points. [0003] However, GPS can only be used under the condition of visible satellites, which greatly restricts the application occasions of GPS; and the positioning accuracy of GPS is relatively low, and the civilian accuracy is within 10 meters. Contents of the invention [0004] In order to solve the above technical problems, the embodiments of the present invention expect to provide a positioning method and device, which have the advantages of high positioning accuracy and small application restrictions. [0005] The technical sch...
