Embodiment Construction

[0026] The present invention provides a mobile terminal and method with an auxiliary positioning function. In order to make the purpose, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The mobile terminal with auxiliary positioning function that the embodiment of the present invention provides comprises GPS module 11, gyroscope 21, accelerometer 31 and microprocessor 41, and described GPS module 11, gyroscope 21 and accelerometer 31 are connected with microprocessor 41 respectively connect. Among them, the GPS module 11 communicates with the microprocessor 41 through the UART (Universal Asynchronous Receiver / Transmitter) serial port, and the gyroscope 21, acceleromet...

Abstract

The invention discloses a mobile terminal having an auxiliary positioning function and a method. The mobile terminal comprises a global positioning system (GPS) module, a gyroscope, an accelerometer and a microprocessor, wherein the GPS module, the gyroscope and the accelerometer are respectively connected with the microprocessor. By the mobile terminal having the auxiliary positioning function and the method provided by the invention, angular speeds and angles of the mobile terminal around an X axis, a Y axis and a Z axis are tested by using the gyroscope; the forward acceleration of the mobile terminal is measured by the accelerometer, and the current speed of the mobile terminal is calculated; and according to initial longitude and latitude coordinates, an initial altitude and an initial current speed, which are acquired by the GPS module, the final longitude and latitude, the final altitude and the final forward speed of the mobile terminal are calculated, so when a GPS signal is abnormal, the function of continuously positioning and navigating the mobile terminal is realized, a user cannot feel the change of GPS application functions completely, and a good use experience effect is achieved.

Description

technical field [0001] The invention relates to GPS positioning technology, in particular to a mobile terminal and method with auxiliary positioning function. Background technique [0002] People generally use GPS (Global Positioning System, Global Positioning System) technology for positioning and navigation when they travel far or are not familiar with the route. However, in some environments (such as tunnels, mountain roads), the GPS signal is very weak or the GPS signal cannot be received. In this environment, people cannot use GPS for positioning and navigation, which brings inconvenience to people's driving. [0003] Thereby prior art still needs to improve and improve. Contents of the invention [0004] In view of the shortcomings of the prior art above, the purpose of the present invention is to provide a mobile terminal and a method with an auxiliary positioning function, which can perform auxiliary positioning when the GPS signal is abnormal. [0005] In order...
