Note that the epoch of the 2-line elements is the same as the state vector time. Occasionally these elements are derived from the Goddard Space Flight Center (GSFC) NASA Orbital Information Group (OIG), using Curtis Haases' program VEC2VIF that formats the OIG vectors for use by VEC2TLE. The source of the data can be confirmed by the data format of the vector ; EFG, ft, ft/s = DOD C-Band Radar Network ECI, km, km/s = NASA OIG RAID RBBS ECI M50, ft, ft/s = Rockwell Mission Support Room Drag and B-Star parameters are internally calculated by VEC2TLE using the drag factor. Rev numbers use NASA orbit numbering convention. Dave Cottle -------------- David Cottle IDB Communications.
