     At first I was delighted that TLEs for some long-lost objects
had been updated.  My delight quickly changed to amazement when I
took a closer look at the TLEs for the four objects.  The elsets in
question are reproduced below:

     In the spirit of TRW's May 16th patent of medium-earth-orbit
satellite-based cellular telecommunications system, I have a patent
application pending for orbits with ten-year periodicities.  As these
element sets demonstrate, the orbital mechanics are relatively
insensitive to the usual parameters such as inclination and orbital
period.  The main ingredient common to all of these objects seems to
be indifference as to their whereabouts on the part of Space Command.
Also notice that the ten-year periodicity is perturbed by the effect
of leap seconds.

     I haven't had a chance to use the new elements to observe any of
these objects, but I've already begun planning for planning for
observations in 2005 when they will be valid again.

     BTW, the new elements are presented in an ORBITEL-processed format
which reconstructs the checksums recently jettisoned by Space Command.
That May surprise has given rise to a new verb, as in the following
example:

           I was finally getting to the point where I could get
           some useful research results when I was Cheyenned and had
           to rewrite all of the database routines for the third time
           in the last two years.

     Be aware that there are still some bugs in the new Space Command
format which causes the data fields in line 2 for some element sets to
be displaced one byte to the left (i.e., with the line 2 object number
immediately following the line number rather than with an intervening
blank) as relayed by the RBBS.
