算法

说明：  matlab版GPS卫星模拟器。给出了详细的设计说明，有很多简化和不完善的地方，旨在抛砖引玉！(Matlab version of the GPS satellite simulator. Given the detailed design specifications, and to simplify a lot of imperfections, and to congregate!)

说明：  GPS软接收机.包括：捕获，跟踪，伪距计算，位置解算等等。(GNSS SDR)

说明：  针对高动态 环 境 下 突 发 信 号 检 测 问 题，提 出 基 于 高 阶 项 逐 级 消 去 的 非 线 性 调 频 （ｎｏｎ－ｌｉｎｅａｒ　ｆｒｅｑｕｅｎｃｙ ｍｏｄｕｌａｔｉｏｎ，ＮＬＦＭ）信号参数估计算法，利用合理近似，将其转化为相对简单的线性调频 （ｌｉｎｅａｒ　ｆｒｅｑｕｅｎｃｙ　ｍｏｄｕ－ ｌａｔｉｏｎ，ＬＦＭ）信号参数估计问题，并提出两级调频率逼近法用于ＬＦＭ 信号参数估计，具有原理简明、计算复杂度低 等特点，便于实际工程应用．(To detect burst signals in high dynamic environment, a non-linear frequency modulation (NLFM) based on high-order item elimination is proposed. Modulation (NLFM) signal parameter estimation algorithm, using reasonable approximation, is transformed into a relatively simple linear frequency modulation- The problem of LFM signal parameter estimation is discussed. A two-stage frequency modulation approximation method is proposed for LFM signal parameter estimation. It has simple principle and low computational complexity.)

INS-GPS 惯性-天文组合导航 这个导航算法基于MATLAB环境，需要有惯性、天文的测量数据，最后结果是三个姿态角，以及一些误差信息。(Inertia- Astro Navigation I completed my graduation this design so that)

说明：  读取广播星历（n文件），并计算出卫星的位置(Read the broadcast ephemeris (n file), and calculate the position of the satellite)

【实例简介】

GPS三颗卫星的并行捕获仿真，希望对大家有帮助(GPS 3 satellites capture parallel simulation, in the hope that everyone has to help)

gps伪随机码生成与信号捕获程序&数据,matlab仿真(GPS pseudo random code generation and signal acquisition program & data, matlab simulation)

对GPS和DR组合导航的数据进行卡尔曼滤波处理(The GPS and DR integrated navigation Kalman filter data processing)

说明：  通过广播星历自动计算某卫星一天内各时刻的位置，并和同目录精密星历比对精度。注释很多。(The position of each time in a day is calculated automatically by broadcast ephemeris, and the accuracy is compared with that of precise ephemeris in the same catalog. There are many comments.)
