首先,让我们明确一下ECEF坐标系和LLA坐标系分别是什么。ECEF坐标系是地球固定坐标系,它以地球质心为原点,在其内部定义了一个右手笛卡尔坐标系。ECEF坐标系中的坐标点由三个直角坐标值(x, y, z)表示。 而LLA坐标系由经度(Longitude)、纬度(Latitude)和海拔高度(Altitude)共同定义。经度表示点在地球表面东西方向上的...
The ECEF Position to LLA block converts a 3-by-1 vector of ECEF position (‾‾p) into geodetic latitude (‾‾μ), longitude (‾ι), and altitude (‾h) above the planetary ellipsoid. For more information on the ECEF position, see Algorithms. ...
GPS使用的三种坐标系ECEF、ENU、LLA坐标系 GPS使⽤的三种坐标系ECEF、ENU、LLA坐标系 1.地⼼地固坐标系（Earth-Centered,Earth-Fixed，简称ECEF）简称地⼼坐标系，是⼀种以为原点的（也称），是⼀种。原点 O (0,0,0)为地球质⼼，z 轴与平⾏指向，x 轴指向与的交点，y 轴垂直于xOz平⾯(即...
I'm trying to convert a WGS84 lon, lat and alt to ECEF and Pyproj is giving me really weird results. My code is simply: lon, lat, alt = 49.74761271 -113.2179781 0 ecef = pyproj.Proj(proj='geocent', ellps='WGS84', datum='WGS84') lla = pyp...
