Abstract

In order to solve the problems of electromagnetic interference and electromagnetic compatibility when satellite positioning navigation chips are integrated into a module, the invention provides a satellite positioning navigation module of a mobile terminal. The problems of the electromagnetic interference and the electromagnetic compatibility are eliminated or reduced through reasonable arrangement of pins. The satellite positioning navigation module can be widely applied to the mobile terminal.

Description

technical field [0001] The invention belongs to the hardware technology of mobile communication and satellite navigation. Background technique [0002] The hardware structure of the existing mobile terminal is mostly that each component is directly connected to the main board, and the satellite positioning and navigation (GPS) chip is also directly arranged on the main board of the mobile terminal. The disadvantage of this setting scheme is that after the satellite positioning and navigation chip is connected to the motherboard, an overall test is required. If there is a problem in the test and modification is required, a comprehensive modification of the motherboard is required. When multiple components are installed on the motherboard of the mobile terminal (this is a common situation), repeated testing of multiple modules will lead to a long development cycle and high development costs. [0003] The satellite positioning and navigation chip and related circuits are integ...
