This book is about global NaviGAtion satellite systems (GNSS), their two main instru- ments, which are a receiver and a simulator, and their applications. The book is based on an operational off-the-shelf real-time software GNSS receiver and off-the-shelf GNSS signalsimulator.Theacademicversionsofthesetoolsarebundledwiththisbookandfree for readers to use for study and research.

当前全球定位系统（NaviGAtion Satellite Timing And Ranging Global Position System，简称GPS）广泛应用于舰船导航，航空航天，地理测绘等领域，特别是移动式定位系统对于目前的城市交通管理有着非常重要的意义。本文分析了当前交通管理中的实际问题，介绍了一种车载终端的设计方法。设计采用ARM9内核的S3C2410微处理器构造的嵌入式系统，可以实现对GPS定位信息的接受和处理，并采用嵌入式Linux操作系统，结合开放式Linux图形软件Qt，可以为后续的建立地理信息系统（Geographic information system，简称GIS）提供数据支持，是集GPS全球卫星定位系统和通用分组无线业务（General Packet Radio Service，简称GPRS）无线通信技术于一体的新型电子产品。它为现代交通运输提供了新颖，可靠，有效的控制和管理途径。 车载终端通过将GPS模块的定位信息提取出来，一方面将定位信息在车载终端上显示，一方面又结合车辆的状态信息通过GPRS模块发送出去，该信息通过无线公共网络传输给车辆管理部门。车辆管理部门根据车辆的位置和状态等，结合GIS系统中的地图信息提供GPS数据的差分修正，并采取一定的措施，从而实现车辆的有效管理。 本设计从硬件和软件两大部分出发，硬件上设计了ARM处理器、存储器、内存及其外围电路，另外还有GPS模块电路和GPRS模块电路；软件上采用Qt的人机界面完成数据显示与更新，采用PPP拨号脚本完成GPRS模块的拨号，通过Qt多线程编程的方法完成GPS数据的提取和GPRS的信息发送。在硬件和软件之间采用了嵌入式Linux系统，包括启动代码、内核和文件系统等。

In 1960, R.E. Kalman published his famous paper describing a recursive solution to the discrete-data linear filtering problem. Since that time, due in large part to advances in digital computing, the Kalman filter has been the subject of extensive research and application, particularly in the area of autonomous or assisted NaviGAtion.

In 1960, R.E. Kalman published his famous paper describing a recursive solution to the discretedata linear filtering problem [Kalman60]. Since that time, due in large part to advances in digital computing, the Kalman filter has been the subject of extensive research and application, particularly in the area of autonomous or assisted NaviGAtion. A very “friendly” introduction to the general idea of the Kalman filter can be found in Chapter 1 of [Maybeck79], while a more complete introductory discussion can be found in [Sorenson70], which also contains some interesting historical narrative.
