Ecef vectors
WebMar 27, 2024 · You can get the rotation matrices from J2000 to ECEF using SPICE, specifically SPICE's pxform function. Someone else asked about this same topic in another question here ( Is it posible to convert JPL Horizons Vectors to ECEF?) where I showed which SPICE kernels to use in order to calculate ECEF vectors at given times. Web1 Let there be two data points, in ECEF, as follows (in meters): A1 (x1, y1, z1) A2 (x2, y2, z2) I want to calculate the angle, Clock-wise relative to North (the Z-axis in ECEF), that is the heading from point 1 to point 2. I can easily visualize this, and solve it, in 2D.
