1、i GPS 卫星运动及定位 matlab 仿真 作者姓名： 专业班级： 指导老师： 摘要 全球定位系统是具有全球性、全能性、全天候优势的导航定位、定时和测速系统，现在在全球很多领域获得了应用。 GPS 卫星的定位是一个比较复杂的系统，其包含参数众多，如时间系统、空间坐标系统等。此次设计是针对卫星运动定位的 matlab 仿真实现，因要求不高，所以对卫星运动做了理想化处理，摄动力对卫星的影响忽略不计（所以为无摄运动），采用开普勒定律及最小二乘法计算其轨道参数，对其运动规律进行简略
2、分析，并使用 matlab 编程仿 真实现了卫星的运功轨道平面、运动动态、可见卫星的分布及利用可见卫星计算出用户位置。 通过此次设计，对于 GPS 卫星有了初步的认识，对于静态单点定位、伪距等相关概念有一定了解。 关键字： GPS 卫星 无摄运动 伪距 matlab 仿真 ii The movement and location of GPS satellite on MATLAB Abstract： Global positioning system is a global, versatility, all-
3、weather advantage of navigation and positioning, timing and speed system, now there has many application in many fields. GPS satellite positioning is a complex system, which includes many parameters, such as time and space coordinates system. This design is based on the matlab simulation of sa
4、tellite motion and location, because demand is not high, so to do the idealized satellite movement, and ignore the disturbed motion ( so call it non-disturbed motion ).Using the Kepler and least-square method for calculating the parameters of orbital motion, for the characteristics of motion to make
5、 a simple analysis, and use the matlab simulation to program achieve the orbital plane of satellite, the dynamic motion, the distribution of visible satellites and using visible satellites to calculate the users home. Through the design have primary understanding for the GPS satellite, and understanding the static single-point, pseudorange and so on. Key words： GPS satellite non-disturbed motion pseudorange matlab simulation
