JY1SAT (JO-97) CubeSat

JY1SAT (JO-97) carrying the FUNcube-6 amateur radio transponder and ESEO with the FUNcube-4 transponder were launched on December 3, 2018.

JY1SAT – Although not finally confirmed, good tracking results are being obtained using the TLEs for object 2018-99AX / 43803, the 1200 bps BPSK telemetry beacon is on 145.840 MHz.

Commissioning of the spacecraft is continuing and there may be some changes to the operating modes over the next couple of weeks. Please continue to let the Data Warehouse have as much data as possible. In that regard, an updated version of the JY1SAT Dashboard (ver 1189) has just been released. This fixes a couple of buggettes relating to Doppler tracking over multiple orbits and the graph displays now no longer start at zero. This update v1189 JY1 Dashboard can be downloaded from https://download.funcube.org.uk/JY1Sat_Dashboard_v1189.msi

ESEO – In a similar manner to JY1SAT, the official confirmation has not been received, but the best TLEs are currently 2018-99AL / 43792. The 9600 bps downlink signal on 437.00 MHz is quite strong and reports and recordings are welcomed. Please continue to check the https://www.esa.int/Education/ESEO website for the latest updates from ESA.

We can confirm that the AMSAT payload with a downlink on 145.985 MHz has not yet been activated and that DK3WN and EA4GPZ, working with other collaborators, have developed a decoder for the 437.00 MHz downlink signals.

FUNcube Payload Telemetry Dashboards

JY1SAT CubeSat

JY1SAT CubeSat

Sunday, December 2, 2018 should see two more satellites carrying FUNcube payloads launched into orbit.

With that launch, JY1Sat and ESEO will join FUNcube-1 (AO-73) and Nayif-1 (EO-88).

The FUNcube team have been busy, not only designing and implementing the payloads, but also working on the Telemetry Dashboards and the Data Warehouse.

Each satellite has a dedicated dashboard and we have created a one page summary (FUNcube Dashboard Summary v1) of those dashboards, their current version number and a dedicated download link.

Telemetry Dashboard

We have included the recommended warehouse settings for each satellite as well as the “FCD Centre Frequency”. Note that the frequency we quote is 20 kHz offset from the published telemetry downlink to allow for the zero Hertz spike and close in phase noise that is inherent on SDRs.

Currently, to view the telemetry for a particular satellite, it is necessary to run the dashboard for that satellite. Any telemetry for one of the other FUNcube satellites can be captured and forwarded to the central data warehouse. For this reason, some users tend to run all dashboards simultaneously using the same FUNcube Dongle. Users should remember the that dashboard that was started last, is the one that will control the frequency settings applied to the FUNcube Dongle.

These dashboards are under continual development and the next planned development is to create a single dashboard that will service all FUNcube Telemetry payloads simultaneously. Keep a look out for further news on this unified dashboard in 2019.

Telemetry Data Warehouse

All telemetry received via the dashboards is forwarded to the central data warehouse, providing you have registered for an account. This has been a very successful part of the FUNcube project as it has allowed for worldwide data collection by amateurs and for all the data to be available to download and used for educational purposes.

With the pending launch of two additional satellites, some changes where required to allow this data capture to continue in an efficient manner. The data warehouse has a new user interface and all satellite data can be assessed with one URL – http://data.amsat-uk.org/

Once at the new user interface, simply select the satellite you are interested in, and all the usual telemetry will be available along with the list of current data providers to the database for that satellite.

Both the dashboards and the data warehouse are under continual development, so be sure to check back for updates.

The FUNcube team is very grateful to all radio amateurs worldwide for their continued support and we encourage you all to join in with the reception of JY1Sat and ESEO telemetry upon a successful launch this Sunday.

The launch of the ESEO spacecraft on board the SSO-A flight from Vandenberg is scheduled for 18:31:47 GMT on Monday, December 3.

The ESEO microsatellite includes a FUNcube payload which will provide similar telemetry to its predecessors but will have a more powerful transmitter and thus be even easier to hear. For amateurs, this payload will also provide a single channel L/V transponder for FM. These downlinks will be transmitted on 145.895 MHz and the FM transponder uplink will be on 1263.5 MHz with a 67 Hz PLL tone required.

A new Dashboard has been developed for this mission and is available for download ESEO Dashboard ver 1177

The AMSAT FUNcube Payload Downlink Data document gives all the information required to decode the telemetry ESEO_Downlink_Data_1_21a

The new Dashboard will operate in exactly the same manner as those developed for previous missions and general set-up information can be downloaded here: Dashboard Guidance

A new Data Warehouse has also been created. This can be used to view the telemetry from ALL of the FUNcube missions: http://data.amsat-uk.org/

We expect that the FUNcube telemetry transmitter will become operational after the launch and subsequent to the completion of initial de-tumbling of the spacecraft.

Thanks for your valuable support for this mission!

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, currently scheduled for Wednesday, November 28 at 18:32 GMT.

Watch the launch live at
https://www.youtube.com/watch?v=PJkRM5QQDAA

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

ESEO’s Educational Story Continues

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 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.
