gps导航工具包，可用于分析GPS误差，伪距及导航融合算法(This report include the review of • Principle of Radio Navigation: navigation base on trilateration has been investigated and the over determined Eq. for navigation has been solved. • GPS Ephemeris Data: for GPS navigation, the position of GPS satellite is very important so the by receiving ephemeris data the position of the satellite is determined. • GPS Errors: Three different sources of errors in GPS navigation has been investigated (Ionosphere, Troposphere and Satellite clock). Ionospheric Error model is generated base on Parkinson [1] and the Tropospheric Error Model based on Hopfiel model [2]. • Simulation & GPS Toolbox: One of the targets of this work is generating Matlab GPS Toolbox and in one case study the performance of generated toolbox will be verified.)

说明：  介绍了北斗双星定位系统的特点、 功能、 系统组成和工作原理， 说明了北斗有源定位方式在应用方面的局限性.对搞BD无源定位而言，是篇很有用的论文，在此分享。(Introduced Beidou Positioning System features, functions, composition and working principle of the system, indicating the way Beidou active positioning application limitations. Right out BD passive positioning, the paper is very useful articles in this share .)

Very good article about color and texture descriptions for CBIR.

一个很不错的仿真设计方案，强烈推荐看看！(A very good simulation of the design program, strongly recommended to see!)

说明：  单回路整定，主要对象为锅炉汽水系统，所运用的方法为三冲凉控制。(Single-loop tuning, the main target for the boiler water system, the method used for the control of the three showers.)
