AO-40 update

AO-40 is now at approximately ALON/ALAT = 45/24.

As we have reached our desired ALON/ALAT and the sun is in prime position for the move, we have stopped magnetorquing and will begin drifting immediately. The passbands have been turned off and will remain off for approximately 4 weeks. The middle beacon will remain on.

Drift rate is approximately 16 deg/week. We should be in a position to begin lowering ALAT and restarting the passbands during the 4th week in December.

The command team will make every effort to have FEC telemetry active, but this may not be possible on every orbit.

Thank you for your patience.

AO-40 update

We have almost reached ALON=45 deg. and we are beginning to raise ALAT to just above 20 degs.

This will take approximately a week to 10 days. When we are confident that ALAT exceeds 20 degs, we will shut off the passbands (beacon on only) and begin drifting toward ALON ~315 degs. The drift process (passbands off) will take approximately 4 weeks. We can be a little more specific after we know the final spin rate.

UO14 QRT efter 14 år i rymden

The Mission Control Centre at SSTL at the Surrey Space Centre reports that UoSAT-OSCAR-14 has finally reached the end of its mission after nearly 14 years in orbit.

Launched on 22 January 1990 by Ariane, UO-14 was the first 9k6 bps amateur data communications satellite and pioneered the PACSAT communications concept. After approximately 18 months in orbit, UO-14 was switched to commercial frequencies for humanitarian use for Satellite and it was used by them until 1997 when it was switched back to amateur use as an FM repeater where it remained until now.

Since launch, UO-14 has completed over 72,000 orbits and
many charge/discharge cycles of its on-board NiCd battery, however recently one of the battery cells has become
exhausted and can no longer support continuous operation of the repeater (the transmitter shuts down shortly after it is commanded ON due to undervoltage) so the microsatellite s mission has been terminated.

Thank you UO-14 for your long service!
