ESA have released a video of the European Student Earth Orbiter ESEO satellite which carries an amateur radio payload.

ESEO is expected to launch as part of Spaceflight’s SSO-A SmallSat Express mission, on a SpaceX Falcon 9 from Vandenberg Air Force Base. The launch has been postponed, a new date has yet to be announced.

The AMSAT payload, provided by AMSAT-UK in cooperation with the University of Surrey, UK, allows the satellite to establish a downlink connection to hundreds of ground stations in the AMSAT network, sending both housekeeping and scientific data. These data will be used to run science and technology lessons in schools and universities.

Radio amateurs will be able to communicate via the 1260/145 MHz FM transponder.

IARU Coordinated Frequencies:
• Main ESEO Telemetry Beacon 437.000 MHz 4k8 or 9k6 GMSK AX25
• FUNcube-4 Beacon 145.895 MHz 4k8 BPSK
• FM Uplink 1263.500 MHz CTCSS 67 Hz
• FM Downlink 145.895 MHz

Es’hail-2 / P4-A positioning and IOT phase started

Es'hail-2 Mission Patch

Following the successful launch on November 15 of Es’hail-2 on board the SpaceX Falcon 9 launch vehicle, Mitsubishi (MELCO) and Es’hailSat will begin the In Orbit Testing (IOT) program once the satellite has been positioned in a test orbital slot – the positioning should be achieved in the next few days.

The IOT phase will take a few months, during which time the amateur radio payload will not be turned on.

AMSAT-DL will be commissioning the Amateur transponder ground station in Doha with the Es’hailSat control team.

Once IOT is complete, the satellite will be moved to the final orbital slot at 26 degrees and there will be an announcement by AMSAT-DL when the transponders are available for use.

Before this announcement, no attempt should be made to use the transponders as any interference to the test program will delay the release and if excessive interference is seen may cause the satellite owners not to make the facility available for amateur use.

Galileo GNSS/GPS – FCC to vote on use of signals in USA

FCC SealThe Federal Communications Commission (FCC) has said it will vote in November on whether to allow U.S. GPS receivers to access the Galileo global navigation satellite system (GNSS).

From an Amateur Radio perspective the key part is that the FCC will only be voting to waive its licensing requirements for non-federal operations with Galileo channels E1 and E5, subject to certain technical constraints.

This means they will not be voting on the E6 channel 1260-1300 MHz, these frequencies are also Amateur and Amateur-Satellite Service allocations. This suggests for 1260-1300 MHz the situation in the USA will be unchanged, the unlicensed use of the Galileo signal on channel E6 will not be permitted for non-Federal operations in the USA.

ESEO’s Educational Story Continues

Happy ESEO students and AMSAT-UK members

Happy ESEO students and AMSAT-UK members

ESA reports the European Student Earth Orbiter (ESEO) has concluded its test campaign. The ESEO student teams gathered in the Netherlands, October 18, 2018 for a last precious lesson before the satellite is launched.

ESEO carries an amateur radio 1260 to 145 MHz FM transponder and a 1k2 and 4k8 BPSK telemetry beacon developed by AMSAT-UK members.

The satellite has been at ESA’s ESTEC test facilities, in the Netherlands, where it completed the last steps of a thorough satellite test campaign which had started in August 2018 at SITAEL’s facility in Mola di Bari, Italy.

Learning by doing has already proven an amazing experience for the ten university student teams from different European universities who have designed and built the instruments and several key subsystems of the ESEO satellite.

On October 18, at a dedicated workshop, the ESEO students had the additional chance to hear first-hand what it takes to run a satellite test campaign – trouble shooting included!

“In the space sector no satellite could ever be launched without a thorough tests campaign”, said Piero Galeone, coordinating the ESA Academy programme of which ESEO is a part. “The reason is that – as perfect as your satellite design and manufacturing process can be – the devil always hides in the details. If there is anything to be fixed, you want to know it and correct it before the satellite flies on its orbit hundreds kilometres from the surface of the Earth, beyond the reach of any engineer’s hands”.

The special event station GB0AUK will be active on the amateur satellites at the AMSAT-UK Colloquium, part of the RSGB Convention, in Milton Keynes Oct 13-14.

AMSAT-UK members will be running a demonstration amateur radio satellite ground station, using the equipment provided to UK schools for the International Space Station ARISS contacts in 2016.

The station will be operational, as time permits during from Friday, October 12 until Sunday, October 14.

There will also be a ‘Beginners Session’ on Sunday morning at 09:30 BST which, like all the Colloquium presentations, will be streamed live.

The AMSAT-UK Colloquium is part of the RSGB Convention at the Kents Park Conference Centre, Timbold Drive, Milton Keynes, MK7 6BZ. Colloquium presentations will be in Lecture Room 5. Download the programme schedule from
