摘　　要：本文重点讨论了定位仪的硬件和软件系统的设计与实现方法。对硬件系统,给出了主要元器件的电路的设计方法;对软件系统,介绍了获取GPS接收机定位数据的设计方法以及利用GSM短消息实现定位仪与监控中心之间无线通信的设计方法。实际应用效果表明,本文给出的设计方法是合理有效,有很高的实用价值。The design and implementation methods of hardware and software systems of the orientation instrument are discussed in detail. To the hardware system, the circuits design of main components is given. To the software system, the design methods for receiving position data from GPS receiver and for wireless cormnunication based on the GSM short message between the orientation instrument and the monitor center are especially discussed. The practical applications show that the design methods are very valid and practicable.
