摘　　要：GPS全球定位系统(global positioningsystem)具有在海、陆、空进行全方位实时三维导航与定位能力的新一代卫星导航与定位系统。GPS以全天候、高精度等显著特点,在军用、民用、测绘等多种领域有着广泛应用。GPS卫星定位技术在民用领域有着非常广阔的前景,以多接口通用GPS接收系统为设计目标,对GPS接收技术,各种流行的接口技术,电源管理技术,抗干扰技术等作了多方面的研究。并做了实际的测试。成功开发了GARMIN GPS接收机的接口系统,尤其在红外线接口的设计中加入了抗PCB噪声和抗EMI的设计,使得红外数据传输更为稳定。电源管理方面也采用了先进的技术,使得仅一节干电池仍能持续供电数小时。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 endlessfuture in civilian field. Aming at the GPS receiving system, some researches in GPS reception technique, various prevailing interface applications, power management, anti-interference designing are discussed. Practical tests are also done for the designing. We 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.
