    I have generated the following guess:
    
    SBIRS GEO 2 r
    1 39121U 13011B   13206.14342780 0.00002225  00000-0  10769-2 0    02
    2 39121  21.9142 267.5106 7256990 274.7545   7.9326  2.29613940    09
    
    This assumes a fairly small drag term.  Of course the mean motion could
    be off somewhat.  I would hope that the error will be less than about
    5 minutes per day.
