Embodiment Construction

[0036] The current mobile terminal positioning adopts a single-point positioning method, that is, the satellite positioning module equipped on the terminal body receives and calculates the carrier signal of the positioning satellite to achieve positioning. Due to the interference factors such as clock difference, ionospheric delay, and tropospheric delay The influence of the mobile terminal has led to the technical problem of large single-point positioning error of the mobile terminal.

[0037] In view of this, embodiments of the present application provide a mobile terminal positioning method and a mobile terminal, which are used to solve the technical problem of large positioning errors in existing mobile terminal positioning methods.

[0038] In order to make the purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in co...

Abstract

The invention provides a mobile terminal positioning method and a mobile terminal. The method comprises the following steps: acquiring first GNSS data through a locally carried satellite positioning module; acquiring second GNSS data of a reference station terminal; performing double-difference carrier phase difference operation according to the first GNSS data and the second GNSS data to obtain adouble-difference ambiguity parameter; and performing coordinate optimization calculation on the first GNSS data according to the double-difference ambiguity parameter to obtain a positioning coordinate of the mobile terminal. According to the invention, double-difference carrier phase difference operation is carried out based on the GNSS data of the mobile terminal and the GNSS data of the reference station terminal; coordinate optimization calculation is carried out on the first GNSS data according to double-difference ambiguity parameters obtained through differential operation; interference factors existing in a single-point satellite positioning mode are eliminated, so that positioning coordinates with higher precision are obtained, a positioning method with higher precision is realized at the mobile terminal, and the technical problem of large positioning error of an existing mobile terminal positioning mode is solved.

Description

technical field [0001] The present application relates to the technical field of satellite positioning, and in particular to a mobile terminal positioning method and a mobile terminal. Background technique [0002] With the progress of semiconductor technology, the current mobile terminals can be developed in the direction of smaller size and richer functions, and most of the current mobile terminals have basically realized the application of the satellite positioning function. [0003] The current mobile terminal positioning adopts a single-point positioning method, that is, the satellite positioning module equipped on the terminal body receives and calculates the carrier signal of the positioning satellite to achieve positioning. However, this positioning method has a technical problem of large positioning errors. Contents of the invention [0004] The present application provides a mobile terminal positioning method and a mobile terminal, which are used to solve the tec...
