Due to Thanksgiving being on Thursday, the AMSAT-NA TLE Distribution for
this week will be today, November 21, 2017. Next week we will continue with
the normal TLE distribution on each Thursday of the week. Note that, per
comments below, AO-91 is most likely object 43016.
It appears that AO-91 is in the group of cubesats launched on 11-18-17 that
include objects 43016, 43017, and 43018. The object 43015 that we were using
for AO-91 has separated enough to be confirmed as Buccaneer RRM by 18th
Space Control Squadron at Vandenburg AFB, CA. One of 18 SPCS many missions
is launch analysis.
Therefore, based analysis (by Nico Janssen, (PA0DLO) and discussion by Alan
Biddle (WA4SCA), Jerry Buxton (N0JY), Nico Janssen (PA0DLO), Paul Stoetzer
(N8HM) and myself AO-91 is most likely object 43016. Note that these objects
are still very close together and one more change could be needed. The
process of identification is one of waiting for a group of objects to
separate enough to isolate the one you are interested in and positively
identify it's signal as matching a certain TLE set. Simple, right!
For comparison, Buccaneer (object 43015, not AO-91) is now at least 26
seconds from objects 43016, 43017, and 43018. Objects 43016, 43017, and
43018 are still about 2 seconds apart. (Analysis by Nico,PA0DLO)
