用Matlab实现的一个卫星自动导航模拟系统，包括GUI设计、模型设计与实现、三维动态仿真等功能，其中运用了两个自动导航的模型，程序里有对模型的简要说明，如果有需要详细说明的，可以和我联系。-using Matlab a simulated automatic navigation satellite systems, including GUI design, Model Design and Implementation, three-dimensional dynamic simulati

本书采用软件接收机的观点，详细介绍了GPS接收机原理，涉及软件无线电和GPS两个热门领域。GPS接收机包括直接序列扩频信号接收技术和导航处理两个学科内容，涉及卫星星座及GPS信号的影响、信号捕获跟踪、导航电文解扩接收、伪距测量、定位和导航计算处理等内容。本书第2版增加了3章新的内容，主要涉及微弱信号和强干扰环境下，GPS接收机的处理方法。本书还附列了许多用Matlab编写的计算机程序，帮助阐明某些思想，一些可直接用于接收机的设计-This book uses software receiver

用matlab实现GPS原理和接收机设计中卫星速度和位置坐标的计算。可以输入任意信号发射时间计算。-Realization of GPS principle and the calculation of satellite velocity and position coordinates in the design of the receiver using matlab. Can enter any signal emission time calculation.

Texture-Aware Fast Global Level Set Evolution-Due to its intrinsic advantages such as the ability to automatically handle complex shapes and topological changes, the level set method has been widely used in image segmentation. Nevertheless, in additi
