Embodiment Construction

[0052] 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, not to limit the present application.

[0053] The positioning method provided by this application can be applied to such as figure 1 In the shown application system, the system includes: a reference station 1, a mobile station 2, and at least four satellites. Among them, the base station 1 and the mobile station 2 interact through the network, and both receive satellite signals sent by multiple satellites. During this process, the mobile station 2 also needs to receive the signals sent by the base station 1 in real time and process them to obtain the positioning Location. In practical applications, the mobile station 2 may be...

Abstract

The present application relates to a positioning method and device, a computer device and a storage medium. The method includes the steps of: when signal interruption with a reference station is detected, acquiring the current observed data received by a mobile station in a current epoch, the historical observed data received by the mobile station in a neighboring historical epoch, and the correction number of a stationary orbit satellite; subjecting the neighboring historical coordinate position, the current observed data, the historical observed data, and the correction number to differential single-point positioning process to obtain the current position of the mobile station. The positioning method provided by the present application can achieve accurate positioning in the case of signal interruption.

Description

technical field [0001] The present application relates to the technical field of global navigation satellite system positioning, and in particular to a positioning method, device, computer equipment and storage medium. Background technique [0002] With the continuous promotion of global navigation satellite system (Global Navigation Satellite System, GNSS) application field, carrier phase real-time dynamic differential technology (Real-Time Kinematic, RTK) as a method of real-time dynamic relative positioning using GNSS carrier phase observation value It is a high-precision positioning method commonly used in the GNSS field at present, and is widely used in high-precision measurement fields such as urban surveying, topographic mapping, and construction stakeout. [0003] The commonly used RTK positioning process is: the base station receiver broadcasts the carrier phase observation value and known site coordinates and other information to the mobile station user in real tim...
