Dual-frequency signal positioning method, device, equipment and storage medium for mobile terminal

Abstract

The invention discloses a dual-frequency signal positioning method for a mobile terminal, which relates to the technical field of positioning. The method includes the steps of: acquiring a positioning signal of a first frequency band received by a first antenna to obtain a first positioning signal; wherein, the first positioning signal An antenna is a main antenna or a diversity antenna; filtering the first positioning signal to obtain a filtered first positioning signal; obtaining a positioning signal in a second frequency band to obtain a second positioning signal; according to the filtered first positioning signal A positioning signal and the second positioning signal are used for positioning. The invention also discloses a mobile terminal dual-frequency signal positioning device, equipment and storage medium, which can effectively use the main antenna or diversity antenna of the mobile terminal to improve the quality of the positioning signal received by the mobile terminal, thereby improving the quality of the positioning signal received by the mobile terminal. Positioning accuracy.

Description

technical field [0001] The present invention relates to the field of positioning technology, in particular to a dual-frequency signal positioning method, device and storage medium for a mobile terminal. Background technique [0002] With the rapid development of the national economy, positioning technology has been widely used in many fields of national life and science and technology. At the same time, people's demand for positioning is becoming stronger and stronger. Dual-frequency signal positioning that can effectively improve positioning accuracy It will be the future development trend. [0003] Mobile terminals are generally equipped with WiFi / GPS antennas to receive GPS signals in the L1 frequency band and WiFi frequency band signals. Traditional WiFi / GPS antennas only support receiving GPS signals in the L1 frequency band. The difference is quite large, the traditional WiFi / GPS antenna cannot receive the GPS signal of the L1 frequency band and the GPS signal of the ...

Problems solved by technology

[0004] In the process of implementing the present invention, the inventors found that with the popularity of full-screen and front-rear dual-camera configurations in mobile terminals, the reserved antenna clearance environment is insufficient, and the additionally configured antenna can only be moved to non-clearance areas. When the antenna is in a non-clear area, the metal in the mobile terminal will produce electromagnetic shielding, and the conductive metal will reflect, absorb, and offset electromagnetic waves, resulting in reduced antenna performance such as antenna efficiency and directivity, thereby affecting the performance of the antenna. Omni-directional communication effect, unable to receive high-quality GPS signals in the L5 frequency band, resulting in reduced positioning accuracy
