Videos of the presentations given at the AMSAT-UK International Space Colloquium, which was held as part of the RSGB Convention in Milton Keynes, October 12-13, 2019, are being made available on YouTube.

The first of the videos is the fascinating presentation on the WUSAT-3 CubeSat project given by Professor Julia Hunter-Anderson of the University of Warwick which highlights the potential use of CubeSats for wildlife tracking.

Other presentations are expected to be uploaded in the coming days.

Hurricane Lorenzo: Amateur satellite AO-92 will be available in U/v mode

Drew Glasbrenner, KO4MA, AMSAT VP Operations has received a request from amateurs involved with emergency communications in the Azores, requesting we forego L/v operation on AO-92 this week.

AMSAT News Service reports:

Hurricane Lorenzo is expected to pass through the Azores as a Category 4 storm Tuesday and Wednesday, and they are requesting AO-92 remain in U/v for potential emergency traffic.

Please be aware of and yield to any emergency traffic, on any satellite, coming from the area during this time. Passes covering the Azores and Portugal are the most critical.

We realize that there have been a few moves and cancellations for this mode recently, and I ask for understanding and cooperation.

Emergency use is always first priority, and AMSAT is happy to assist in any way we can.

University CubeSat Club members get ham radio licenses

Students at the Villanova University College of Engineering started a CubeSat Club in the fall of 2018 and have since got their amateur radio licenses.

The university website reports:

A CubeSat is a nanosatellite—a small, lightweight satellite that is cheaper to build than a conventional satellite. They can be launched from rockets, or occasionally from the International Space Station by astronauts. CubeSats send telemetry information—measurements communicated at remote points by automated processes—over radio signals received on earth by a ground station.

The CubeSat club’s 2018-2019 year was packed with a variety of workshops and projects, including:

• Setting up temporary ground stations called SatNOGS (Satellite Network Operators Group)
• Building Yagi-Uda antennas from tape measurers and scrap wood and using them to track low earth orbit satellites as they flew over Villanova
• Building an AMSAT CubeSat Simulator, a functional satellite model
• Assisting with the freshman CubeSat mini-design projects
• Earning amateur radio licenses and ham radio callsigns
• Assembling and selling electronic transceiver boards used in CubeSats as a fundraiser
• Attending the 2019 Hamvention conference and running the AMSAT education table
• Received and decoded a special message sent from the AO-73 FUNcube Satellite especially for Villanova

The students emailed a request to the FUNcube Operations Team to get their special message transmitted from space by the AO-73 satellite. Further information on these ‘Fitter’ messages is available at https://funcube.org.uk/ground-segment/fitter-messages/

Taurus-1 with Codec-2 transponder launched

Taurus-1 with solar sail deployed

Taurus-1 (Jinniuzuo-1) carrying an amateur radio FM to Codec-2 transponder was launched on a CZ-4B rocket from the Taiyuan Satellite Launch Center on Thursday, September 12 at 0326 GMT.

Taurus-1 is a CubeSat project developed by Aerospace System Engineering Research Institute of Shanghai for youth education and amateur radio.

The transponder is similar to that used on LilacSat-1 receiving FM with 67 Hz CTCSS on 145.820 and retransmitting it as Codec-2 9600 bps BPSK digital voice along with the telemetry data on a nominal frequency of 435.840 MHz +/-10 kHz Doppler shift.

On Friday, September 13, Mark Jessop VK5QI tweeted:
“Good signals from #Taurus-1 on 435.840 MHz! Doesn’t look like the FM/Codec2 Transponder is enabled yet though (no response on 436.760 MHz when transmitting on 145.820 MHz)” Note: this was sent before it was realized Codec2 voice and the telemetry were on the same frequency.

Nico Janssen PA0DLO reports the actual telemetry downlink frequency is 435.8387 MHz and Doppler measurements show that Taurus 1 is object 44530 (2019-059C).

New French CEPT paper still seeks 144-146 MHz for Aeronautical

CEPT LogoThe French administration has renewed its attack on the Amateur Radio 144-146 MHz band ahead of a key CEPT ECC CPG meeting in Ankara, August 26-30.

In a paper to be considered at the conference the French Administration says it is not at this time seeking Primary status for the Aeronautical Mobile Service in 144-146, however, their intent is still that the Aeronautical Mobile Service should share the amateur 2m band.

It is clear where such sharing would inevitably lead, amateur operation in the band would only be tolerated if there were no interference to Aeronautical Mobile. Radio Amateurs might be subject to heavy restriction and low EIRP limits.

We can get on idea of France’s long term intent for 144 MHz from their attitude to the 1240-1300 MHz band. It was initially said the Galileo constellation could amicably share this allocation and amateur operation could continue but now France says “unregulated use of the band 1240-1300 MHz by the amateur service is a serious source of harmful interference to RNSS receivers.”

144-146 MHz WebSDR at Goonhilly now available

Goonhilly 144 MHz WebSDR

Goonhilly 144 MHz WebSDR

AMSAT-UK and BATC have announced the availability of a new 144-146 MHz Web-based Software Defined Radio installation at Goonhilly.

This is being provided in collaboration with Goonhilly Earth Station where it is kindly hosted alongside the existing receiving equipment for the amateur radio transponders on the Qatar-Oscar-100 (QO-100 / Es’hail-2) geostationary satellite.

It shares the same Turnstile antenna that is used for the reception of the AO73, EO88 & JO97 CubeSats.

Being located in the far South West of the UK, it is anticipated the SDR will be useful for early Acquisition of Signal (AOS) of 144 MHz downlinks from amateur satellites and the International Space Station (ISS). Additionally it can be used for reception of tropospheric signals from the south – the Spanish beacon ED1ZAG on 144.403 MHz has been already been heard on the system.

The new 144 MHz band WebSDR is available at https://vhf-goonhilly.batc.org.uk/

The AMSAT-UK / BATC 10 GHz WebSDR for QO-100 is still available at https://eshail.batc.org.uk/
