摘要:

介绍了GPS接收原理及模块化接收机的组成,分析了NMEA-0183协议及其解码过程,设计了基于GPS卫星授时时钟,其具有实时性、同步性以及高精度的特点,是无线电波授时所无法比拟的,模块化GPS接收机使GPS接收设备设计更简单、成本更低。

关键词: GPS, 模块化, NMEA-0183协议, 单片机, 授时

Abstract:

This article introduces GPS receiver principle and composition of modular receiver,analyses the NMEA-0183 protocol and decoding process,designs a GPS-based satellite time clock with the advantages of real-time,synchronization and high-precision,which is far superior to radio wave timing.Modular GPS receivers are simpler in design and lower in cost.

Key words: GPS;modular;NMEA-0183 protocol;microcontroller;timing
