[sarex] STS-99 Nominal Orbital Data

["Kenneth J. Ernandes" <n2wwd@xxxxxxxxxxxxxx>]

Below is the nominal State Vector and Keplerian Elements for 
STS-99.  The vector data comes from NASA; the Keplerian Elements 
were computed from the vector.  

This file may be read by VEC2TLE version 9648 to update your 
Keplerian Elements text file.

Note that "99999" is a temporary catalog number.  A permanent 
catalog number and international designator will be assigned when
STS-99 is launched.

The following Keplerian elements were computed by VEC2TLE from this
vector, using a 0.5 drag multiplier:
