H31GPS
- H31GPS模拟接收机程序 H31GPS模拟接收机程序是用来模拟接收GPS卫星数据并显示卫星位置的模拟程序,数据来自己卫星星历。-this is made to test the GPS ,and the data is come from the GPS star.
精密星历文件读取
- 实现对精密星历数据的读取,并能内插出任意时间点卫星的位置,且能评定内插的精度.-to achieve precise ephemeris data to the reader, and interpolation from any point in time the satellite location and can assess the accuracy of interpolation.
Map-matching-model-at-complex-roads
- 车辆导航离不开导航电子地图,地图匹配方法是连接卫星定位信息与导航电子地图的桥梁,即通过一定 的算法,根据定位信息,在导航电子地图上确定出车辆当前所行驶的道路,并在地图上实时准确地显示车辆 的位置[1]. 一套匹配准确率高、实时性好、易于工程实现的地图匹配算法是优秀车载导航产品的重要保 障[2 - 3]. 目前,大多数导航产品仅采用独立的GPS 定位方式,地图匹配方法也大部分采用基于点的投影算法, 算法简单,没有将道路的网络特征考虑进来,特别在面对复杂道路时,容易出现匹配错误,造成
SKY_VIEW
- 通过计算卫星的方位和高度角,从而以极坐标的形式在天空图上把卫星的位置标定出来,十分直观有效。-Computing satellite azimuth and elevation angle, and thus the form of polar coordinates on the sky map the location of the satellite calibration, is very intuitive and effective.
RyxGps
- 这是一个模仿卫星位置检测的,或许以后还会变成是真的-This is a parody of the satellite position detection, and perhaps the future will turn out to be true. .
