The FASTRAC team is excited to announce that the FASTRAC satellites
will launch into space this month on November 19th, 2010! This launch
marks the culmination of seven years of dedicated work by over 120 University
of Texas students.

Robert Bruninga wrote it on amsat-bb:
We just played with the elements for PCSAT and changed the
inclination to 72 degrees and mean motion until we got 650km
and then adjusted RAAN until we got the orbit over Kodiak, and
then changed the EPOC time until we got the satellite over
Kodiak at launch time.
Here are the elements we ended up with:
Epoc 11/19/2010 04:30 UTC
MA 140
MM 14.7
Inc 72
E .0018
AP 16.08
RAAN 130
Based on a launch at 01:24 UTC on the 20th, the first pass in
range of Hawaii and California, will be in minutes and probably
the satellite will not have separated or be activated. But a
half orbit later, the first ground stations will be Eastern
Europe. Then a descending pass over Hawaii at T + 100 minutes
and then Central Europe about 3 hours after launch followed by
Japan and New Zealand. The next pass is over Europe Japan and
NZ again, Not until almost 9 hours later will we see it on the
east coast.
All of these first 3 passes in the Northern Hemisphere begin
about 4 AM through 7:30 AM local time. New Zealand passes are
in the Afternoon.
All of the above can be TOTALLY Wrong and groundless if our
assumptions are wrong.

FASTRAC mission update from JSC Amateur Radio Club, 24 Nov 2010
http://www.dk3wn.info/p/?p=18588
FASTRAC-2 (Emma)
FAST-2 is alive, needs a reset, and has not been commanded yet.
FAST-1 and FAST-2 remain attached as planned.
FAST-2s 1200 bps 3-minute beacon (145.825 MHz) reverted to 9600bps
at two minute intervals over night last night. This indicates that the
TNC reset itself and the on-board microprocessor wasnft responsive to
restore the settings. This is not serious, but we canft reset things
until we can command the satellites.
FAST-2s 1200bps beacon had not been updating for the last couple of
days which told us at the least, the I2C bus had locked up some time back.
We knew this would happen periodically before launch, so this behavior is
not unexpected.
FAST-2 has been actively rejecting 9600bps crosslink requests from FAST-1
at 10-minute intervals due to the I2C bus lockup. They had previously
been heard by several stations around the world crosslinking the first
few orbits after launch Friday evening.
FAST-2s downlink frequency seems to be about 2-3kHz higher than
advertized, so we know the coms subsystem is not at room temperature.
FASTRAC-1 (Sara Lily)
FAST-1 is alive, is beaconing, is attempting to crosslink with FAST-2,
but the 437.435 MHz downlink is much weaker than predicted. Nobody to my
knowledge has been able to decode beacon data from FAST-1 yet.
FAST-1s UHF beacon (437.345 MHz) is much weaker than FAST-2.
We have heard it occasionally but just above the noise floor.
FAST-2s responses to FAST-1s connect requests lead us to believe
that FAST-1 is most likely functioning normally.

FASTRAC Beacon Converter was developed by DK3WN.
Zur Dekodierung der BTEXT Bake von FAST1 und FAST2 ist dieses kleine Tool
gedacht. Einfach den empfangenen Bakenstring (beginnt immer mit F1 oder F2)
in das obere Fenster kopieren und die dekodierten Werte werden angezeigt.
Es ist wichtig, dass die Bakenlange 122 Zeichen betragt
