The European Student Earth Orbiter (ESEO) satellite carries the AMSAT-UK FUNcube-4 amateur radio 1260/145 MHz FM transponder. On September 27 it successfully completed the vibrations test.

In the past few years, ten student teams from different European universities have combined forces to produce essential equipment for the spacecraft, including subsystems parts, scientific or technology demonstration instrumentation, and the ground mission control support for this micro-satellite mission, planned to fly to Low Earth Orbit later this year.

The project reached an important milestone on August 28, 2018, when the assembly integration of the ESEO spacecraft was declared complete. In this phase all the satellite’s physical parts were assembled together, and all functional interconnections were checked to confirm they work as required.

On September 27, 2018 ESEO reached another key milestone, when it successfully completed the vibrations test campaign at SITAEL’s premises in Mola di Bari, Italy. ESEO has now demonstrated that its design is solid enough to safely withstand the mechanical solicitations it will undergo during the rocket launch.

In the next couple of weeks it will undergo the so-called thermal vacuum and electromagnetic compatibility (EMC) tests at ESA’s ESTEC site in the Netherlands.

A unique event is taking place at The Royal Mint Experience, The Royal Mint’s new visitor centre in Llantrisant, Wales from July 30 to August 5, 2017. Local school children and members of the public have been invited to “The Royal Mint Radio Experience” to enjoy a fun, informal and interactive workshop.

They’ll have the opportunity to send and receive radio signals with FUNcube-1, an educational satellite launched in 2013 which is used by schools and educational groups all around the world. Visitors will also exchange greeting messages with radio enthusiasts across the world and, as each country is contacted it will be logged on a large map. The target is to contact each of the 100 countries with which the Royal Mint has worked during its 1,000 year history! The national amateur radio societies in many of those countries have contacted us to say that their members are looking forward to greeting the children on air.

In addition, during the sessions each person will be able to learn how to send their name using Morse code and will receive a special certificate to confirm their achievement.

RSGB General Manager Steve Thomas, M1ACB said: “We’re delighted to be supporting this event which will give visitors to the Royal Mint a chance to experience the wonder of amateur radio and satellite communication. Amateur radio has many links with the science, technology, engineering and maths (STEM) curriculum and can lead to rewarding careers.”

Members of the Radio Society of Great Britain (RSGB), Barry Amateur Radio Society (BARS) and AMSAT-UK will be running the special amateur radio station whose call sign GB4RME (GB 4 Royal Mint Experience) has been granted by Ofcom just for this event.

RSGB Regional Manager and BARS Chairman Glyn Jones, GW0ANA added: “We believe this is the very first time any amateur radio station has been allowed to operate from a Royal Mint anywhere in the world, so it really is a unique occasion!”

The FUNcube-1 Fitter message transmitted by the satellite says:
“Greetings from space to visitors, staff and team G B 4 R M E . Amateur Radio special event and demonstrations at the Royal Mint Experience South Wales. 30 Jul to 5 Aug.”

The Eastern Daily Press report the Bittern DX Group in North Walsham have been awarded £10,000 by the Big Lottery Fund.

The newspaper story says:

The award will help them continue to introduce people to the world of technology, and the possibilities that radio communication can offer people.

But the news wasn’t only celebrated in North Walsham, or even Norfolk, as the announcement was transmitted from a satellite orbiting the Earth.

The satellite, FunCube1, as built by members of the Amateur Radio community and launched into orbit on 21st November 2013.

It was built with the goal of enthusing and educating young people about radio, space, physics and electronics, and is the first satellite with outreach as its primary mission and demonstrates the depth and breadth of the hobby of Amateur Radio.

The Bittern DXers hope that with their new funds they can continue to work on initiatives such as the Educational Outreach Project which entails the group taking their equipment to public events and teach people about their hobby.

FUNcube Satellite Status June 2017

AO-73 (FUNcube-1) – Image credit Wouter Weggelaar PA3WEG

AMSAT-UK has released the FUNcube satellite status update report for June 2017.

AO-73 FUNcube-1

The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from PM Fridays UTC to PM Sundays UTC) the transponder is operational 24/7.

When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, e.g. Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC)

The nominal transponder frequencies are:

Uplink: 435.150 – 435.130 MHz LSB (Inverting)
Downlink: 145.950 – 145.970 MHz USB
Telemetry Tx: 145.935 MHz BPSK

(The passband may be up to 15 kHz higher depending on on-board temps. Lower temperatures give higher freqs!)

FUNcube-2 (aka FUNcube on UKube)

The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC).

The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit).

The nominal transponder frequencies are:
Uplink: 435.080 – 435.060 MHz LSB (Inverting)
Downlink: 145.930 – 145.950 MHz USB
Telemetry Tx: 145.915 MHz BPSK

(The passband may be up to 10kHz higher depending on on-board temps. Low
temperatures give higher freqs!)

EO79 FUNcube-3

Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience.

The nominal transponder frequencies are:
Uplink: 435.0723-435.0473 MHz LSB (Inverting)
Downlink: 145.946-145.971 MHz USB

Further detailed info on EO79 transponder frequencies is at:
https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/

EO88/Nayif-1/FUNcube-5

EO88 is presently operating in autonomous mode. The transponder is operational when the satellite is in eclipse, i.e. the solar panels are NOT being illuminated.

When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power.

The transponder frequencies are:

Uplink: 435.045 – 435.015 MHz LSB (inverting)
Downlink: 145.960-145.990 MHz USB
Telemetry Tx: 145.940MHz

All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very grateful for the assistance given by Innovative Solution In Space Bv, The Netherlands.

FUNcube-1 was launched at 07:10 UT on November 21, 2013 and its first signals were received immediately after deployment over the Indian Ocean by amateurs in South Africa. Since then it has been operating continuously in either its education mode or, with the transponder active, in amateur mode when in eclipse and at weekends.

The FUNcube team are very grateful to everyone who has been contributing their telemetry records to the Data Warehouse and also to those who are using FUNcube-1 for educational outreach to schools and colleges around the world. This important part of our mission is intended to encourage young people to develop an interest and passion in all STEM subjects for their future.

The spacecraft is operating nominally – the telemetry indicates that all the sub-systems are fine. The battery voltages, solar panel charge currents and on board temperatures are virtually unchanged since launch.

In addition to FUNcube-1, there are now similar FUNcube transponders operating in low earth orbit on the UKube-1 and EO79/QB50p1 CubeSats.

The team has recently contributed to the development of Nayif-1, which is presently awaiting launch, and is currently working on a number of further CubeSat and microsat projects.

Happy Birthday AO73!
