Embodiment Construction

[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0046] refer to figure 1 , the embodiment of the present application provides a positioning method, including steps:

[0047] S1. Acquiring location information of two positioning base stations;

[0048] S2. Obtain the relative distance information between each of the two positioning base stations and the object to be positioned multiple times, and simultaneously obtain the height information and speed information of the object to be positioned multiple times;

[0049] S3. Calculate the location information of the object to be positioned.

[0050] As described in step S...

Abstract

The invention discloses a positioning method, a device, computer equipment and a storage medium. The method comprises the steps of acquiring position information of two positioning base stations; acquiring relative distance information of each one of the two positioning base stations and an object to be positioned for multiple times, and meanwhile, acquiring height information and speed information of the object to be positioned for multiple times; calculating position information of the object to be positioned. Accurate positioning can be realized through the two positioning base stations bybeing assisted by the height information and the speed information of the object to be positioned, so that the technical problem that positioning cannot be carried out when no positioning signal exists or the positioning signal is weak is solved, and accurate positioning can be carried out even under the conditions with shielding or indoors.

Description

technical field [0001] The present application relates to the field of positioning, in particular to a positioning method, device, computer equipment and storage medium. Background technique [0002] Positioning systems and positioning devices are becoming more and more popular, and have been widely used in various industries. Commonly used positioning systems such as Beidou Satellite Navigation System (BDS), Galileo Satellite Navigation System (GALILEO), GLONASS (GLONASS) and Global Positioning System (GPS) are used to locate the object to be measured, but due to long-distance communication, making There are errors in the positioning accuracy, and because the distance is too far, the required sensitivity is very small, which makes the anti-interference performance very poor, and it cannot be accurately positioned in an occluded or indoor environment. Errors include: [0003] φ=ρ+c(d r -d s )+λN+d trop -d ion +d rpa1 +ε(φ) [0004] φ—phase measurement value, unit: m ...
