Elements derived from observation arc 2003 Oct 18 - 21 UTC:

DMSP F16         0.0  0.0  0.0  6.2 v
1 28054U 03048A   03294.76813583  .00000188  00000-0  10000-3 0    07
2 28054  98.9218 328.3735 0006236 255.9425 104.1054 14.13369706    03

Decay term is a fixed estimate; all other elements were allowed to vary.

WRMS residuals = 0.015 deg

Similar result to USSTRATCOM's elset nearest in epoch:

1 28054U 03048A   03294.69734068  .00000128  00000-0  92008-4 0   169
2 28054  98.9225 328.3073 0006662 268.6770  91.3638 14.13370827   420

To facilitate direct comparison, here is the hobbyist elset precessed to the
same ascending node as USSTRATCOM's elset:

1 70000U          03294.69734353  .00000188  00000-0  10000-3 0    09
2 70000  98.9218 328.3029 0006236 256.1428 103.9050 14.13369679    05

Orbital periods agree to within 0.005 s; inclinations agree to within 0.0007
deg; RAANs agree to within 0.0044 deg; perigees agree to within 0.62 km.
