Updated CubeSat Element Guesses




Hello:

See below for updated guesses as to the orbital
elements for the recently launched CubeSats.
These are ONLY GUESSES and have *not* been
confirmed.

If anyone hears the CanX-1 beacon on 437.88 MHz,
please let me know!  Our students are still
experiencing problems with the CanX ground station.

MOST appears to be alive an well, however.

Thanks.
Rob

Dear All,

Below is the summary of orbital status of each objects on the MOM
Launch.  Please note, due to the nature of the launch and the
satellites, observation and object counts may vary and may continue to
vary in the next few days.

We now have two sets of element data, one from NORAD in Cheyenne
Mountain, and the other from NORAD in Millstone Hills.

elements are in close agreement with NORAD-CM, where as some other ones
are new objects.

Note:

** Observations and objects count MAY vary due to the nature of the
satellites, orbit, and the tracking radar system **


Latest Estimates
07/01/2003  15:00 EST
We are considering a new hypothesis based on the NORAD Millstone Hills
Radar Data, sent by Bill Bougas.  We believe as follows:
#27840 - Breeze
#27841 - MIMOSA
#75907 - QuakeSat
#75909 - Cute-I
#75908 - MOST
#76995 - XI-IV (this coincides w/ #75910 from NORAD.CM)
#76996 - DTUsat
#76997 - CanX-1
#76998 - AAUC
The object locations are different from our earlier estimates, however
the spacings, contact conditions, seemed to point to this theory.
Aalborg and QuakeFinder are looking into this theory based on our phone
conversations.
