Embodiment Construction

[0086] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0087] The embodiment of the present invention combines GNSS positioning technology and DR positioning technology to improve positioning performance, and performs non-real-time fusion of GNSS positioning results and DR positioning results through the main processor, so as to reduce positioning power consumption.

[0088] Specifically, GNSS is...

Abstract

Embodiments of the present invention provide a positioning method and device for a mobile terminal, and the mobile terminal. After the first period of time, the main processor obtains M reliable navigation data from the cached N navigation data of the mobile terminal. navigation data, and obtain the cached K position change data of the mobile terminal, and the main processor fuses the M reliable navigation data and the K position change data to obtain the first time The position information of the mobile terminal within the period; wherein, the N pieces of navigation data are obtained by calculating the satellite navigation signals of the mobile terminal received within the first time period, and the K pieces of position change data are calculated by the mobile terminal in the first time period It is obtained by calculating the data monitored by the sensor of the mobile terminal within the first time period. The positioning method provided by the embodiment of the present invention does not need to process positioning data in real time, which reduces the positioning power consumption of the system.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a positioning method and device for a mobile terminal and a mobile terminal. Background technique [0002] Global Navigation Satellite System (GNSS) is a general term for a class of systems that use navigation satellites to achieve positioning. GNSS is a widely used positioning technology that can obtain user coordinates around the world. However, in urban areas, due to the reflection and occlusion of navigation signals, the positioning results may drift or even fail to locate. Dead Reckoning (DR) is a technology that uses sensor modules (such as accelerometers, gyroscopes, magnetic field sensors, etc.) on the mobile terminal to calculate the relative position of the user's movement. Positioning is achieved in the case of occlusion. However, the accuracy of DR will continue to accumulate errors over time, resulting in a decrease in accuracy. [0003] In t...
