Design And Realization Of Universal Multi-Function Interface Of GPS System

GPS (Global Positioning System) is a new generation satellite navigation and positioning system that provide all direction, real time, 3-D navigating and positioning at sea, land, air or anywhere on the planet. All climate, high precision are the most significant features of GPS system, these features made GPS a widely used application in military, civilian or mapping fields. GPS satellite navigation technique has endless future in civilian field. This article made the universal multi-function interface of GPS System as the design goal, and made a lot of researches in GPS reception technique, various prevailing interface applications, power management, anti-interference designing. Practical tests are made for the designing. Successfully developed GARMIN GPS receiver interface system, the IrDA interface with anti-PCB noise and anti-EMI design is the most significant part of the whole project, which makes the IR data transitions more stable. Advance technology in power management made a single AA battery can maintain the system power for couple of hours.
