SPACE SHUTTLE ORBITAL DATA:

These 2-line elements have been generated using Ken Ernandes' program
VEC2TLE using real time state vector data supplied by DOD C-Band Radar
Network courtesy Dave Simonson. 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.
