Satellite reference points for the post-processing methods. (A) The mean reflection point and the position of the CCR panel are used as the reference points for the normal point formation. Laser vector indicates direction from the satellite’s center-of-mass (CoM) to the ground SLR system, and R is the satellite’s radius. (B) The range correction ΔR is a distance from the center of the front face of a retroreflector to the optical reflection point. The θ represents an incident angle between the laser vector and the symmetry axis of a CCR.
