sgp4 2.14-GCCcore-13.3.0

What we today call ‘SGP4’ in fact merges together what in the 1970s were originally two separate satellite propagation routines, but which are now selected automatically: * SGP4 — the ‘Simplified General Perturbations’ model is used for satellites close enough to Earth that their orbit takes less than 225 minutes (3 hours 45 minutes) to complete. * SDP4 — the ‘Simplified Deep Space Perturbations’ model is used for satellites farther from Earth, which take 225 minutes or longer to compete an orbit.
