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.

當前全球定位系統（navigation Satellite Timing And Ranging Global Position System，簡稱GPS）廣泛應用于艦船導航，航空航天，地理測繪等領域，特別是移動式定位系統對于目前的城市交通管理有著非常重要的意義。本文分析了當前交通管理中的實際問題，介紹了一種車載終端的設計方法。設計采用ARM9內核的S3C2410微處理器構造的嵌入式系統，可以實現對GPS定位信息的接受和處理，并采用嵌入式Linux操作系統，結合開放式Linux圖形軟件Qt，可以為后續的建立地理信息系統（Geographic information system，簡稱GIS）提供數據支持，是集GPS全球衛星定位系統和通用分組無線業務（General Packet Radio Service，簡稱GPRS）無線通信技術于一體的新型電子產品。它為現代交通運輸提供了新穎，可靠，有效的控制和管理途徑。 車載終端通過將GPS模塊的定位信息提取出來，一方面將定位信息在車載終端上顯示，一方面又結合車輛的狀態信息通過GPRS模塊發送出去，該信息通過無線公共網絡傳輸給車輛管理部門。車輛管理部門根據車輛的位置和狀態等，結合GIS系統中的地圖信息提供GPS數據的差分修正，并采取一定的措施，從而實現車輛的有效管理。 本設計從硬件和軟件兩大部分出發，硬件上設計了ARM處理器、存儲器、內存及其外圍電路，另外還有GPS模塊電路和GPRS模塊電路；軟件上采用Qt的人機界面完成數據顯示與更新，采用PPP撥號腳本完成GPRS模塊的撥號，通過Qt多線程編程的方法完成GPS數據的提取和GPRS的信息發送。在硬件和軟件之間采用了嵌入式Linux系統，包括啟動代碼、內核和文件系統等。

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.
