How to get earth-centered, earth-fixed coordinates from Skyfield?
The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass. Its most common use is in tracking the orbits of satellites and in satellite navigation systems for measuring locations on the surface of th… WebSep 14, 2024 · The result is showing a difference of 312 in X-axis and 60 in Y-axis, instead, I was expecting around 4 for both. Below is the code I used for Geodetic DD conversion to ECEF XYZ: lat = lat/180*pi; %converting to radians long = long/180*pi; %converting to radians a = 6378137.0; % earth semimajor axis in meters f = 1/298.257223563; % … WebThis page allows you to plot the trajectory of an object flying on a specific orbit around the earth, as seen in an Earth-centered, Earth-fixed frame (ECEF).
