Creates a TLE from two or three observations of a satellite on a single pass. Useful for initial orbit parameters and for unknown satellite identification. This fifth version improves convergence characteristics for the three point fit via F and G series. If more than three points are available, use ELFIND for the initial orbit, then use SATFIT and/or ELCORD to refine the orbit using all the observations.-Creates a TLE from two or three observations of a satellite on a single pass.
