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 is currently scheduled for November 19, 2018 at 18:32 GMT.

Watch the launch live at

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

Es'hail-2 Mission Patch

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.

JY1SAT Launch Information and Dashboard

fre, 16/11/2018 - 15:37
JY1SAT CubeSat

JY1SAT CubeSat

JY1Sat is an enhanced 1U FUNcube. It has been developed for the Crown Prince Foundation in Jordan. The spacecraft has been named in honour of the Crown Prince’s grandfather, King Hussein, who operated using his personal amateur radio callsign which was simply JY1.

In addition to the usual suite of FUNcube capabilities it will also be capable of downlinking images in SSDV format.  This image format, developed by Phil Heron, MI0VIM, for use in High Altitude Balloons, is now also being used from lunar orbit by AO-94.

The telemetry downlink frequency is 145.840 MHz, this will use the usual FUNcube standard 1k2 BPSK format. The linear transponder, for Single Sideband (SSB) and CW modes, will downlink on 145.855-145.875 MHz and uplink on 435.100-435.120 MHz. The transponder is inverting so Lower Sideband (LSB) should be used on the uplink and Uppersideband (USB) on the downlink.

A new Dashboard has been developed for this mission and is available for download here:

This 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 brand new Data Warehouse has also been created. This can be used to view the telemetry from ALL of the FUNcube missions. This can his can viewed here http://data2.amsat-uk.org/

SSO-A Mission Patch

SSO-A Mission Patch

This mission will be one of the payloads on the Spaceflight SSO-A mission. This is currently scheduled to lift-off on Monday, November 19, 2018 at 18:32 GMT from the Vandenberg Air Force base in California. This launch is expected to have more than sixty other payloads. The deployment time for JY1SAT has been advised as 4 hours 31 minutes and 54.5 seconds after launch. This means that, allowing for the pre-programmed delay of 30 minutes between deployment from the POD and the release of the antennas, the first downlink signals cannot be expected until approximately 23:34 GMT on November 19.

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

Here are some initial pre-launch TLEs which we believe will be accurate for at least the first few orbits.

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

tor, 25/10/2018 - 22:36

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.

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 satellite in the anechoic chamber at the ESTEC test facilities, in the Netherlands

ESEO satellite in the anechoic chamber at the ESTEC test facilities, in the Netherlands

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”.

Daniel Estévez EA4GPZ / M0HXM reports decoding a JT4G amateur radio signal from the LO-94 (DSLWP-B) spacecraft that was reflected off the Moon.

Daniel says “JT4G is a digital mode designed for Earth-Moon-Earth microwave communications, so it is tolerant to high Doppler spreads. However, the reflections of the [DSLWP-B] B0 transmitter at 435.4 MHz, which contained the JT4G transmissions, were very weak, so I had not attempted to decode the JT4G Moonbounce signal.”

However, by analysing a recording made on October 19, 2018 at 17:53:35 GMT he was able to decode one of the five JT4G transmissions in the recording.

UKube-1, the UK Space Agency’s first CubeSat, was launched into space in July 2014. It completed its successful nominal mission fourteen month later in September 2015.

Since that date, for the past three years, the FUNcube based payload has continued to provide a transponder for use by radio amateurs and, additionally, 30+ channels of real time telemetry for STEM outreach and for use by schools and colleges. These downlinks have operated continuously on the 145 MHz band and more than 450 stations have supported this ongoing activity. They have uplinked the telemetry data to the FUNcube Data Warehouse where it is stored and available for research.

Just before midnight (UTC) on Thursday 18th October, the Warehouse received a data frame from KB6LTY, Christy Hunter in California. This is the last record of signals being received from the spacecraft and since that date, careful observations have failed to detect any signals from either of the transmitters carried by the spacecraft.

An early analysis of the last telemetry received has not shown any obvious anomalies, but this work continues.

Although it is obviously sad for both the amateur and educational worlds to lose such a valuable resource, both AO73-FUNcube 1 and EO88-Nayif 1 continue to operate nominally and JY1SAT and ESEO are expected to launch before the end of 2018.

International Space Station – Image Credit NASA

Amateur Radio On The International Space Station (ARISS) is planning a very special Slow Scan Television (SSTV) event from about 1000 UT Saturday, Oct. 27 until 1930 UT Monday, Oct. 29 on 145.800 MHz FM using PD-120.

Helping to support the event will be NASA’s Space, Communication and Navigation (SCaN) Department.

The Space Communications and Navigation (SCaN) program manages NASA’s three most important communications networks: The Space Network (SN), Near Earth Network (NEN), and the Deep Space Network (DSN).

Just as in past ARISS SSTV commemorations, twelve images will be downlinked, but this time with six featuring the SCaN educational activities while the other six images will commemorate major NASA anniversaries, ie., when NASA was established, astronauts first landing on the moon, etc.

In addition to the fun of receiving these images, participants can qualify for a special endorsement for the NASA On The Air (NOTA) celebration event. To learn more about NOTA visit https://nasaontheair.wordpress.com/

Once received, images can be posted and viewed at

The transmissions are expected to be broadcast at the usual frequency of 145.800 MHz using the PD-120 SSTV mode.

Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time.

Source AMSAT News Service

Note the ISS transmissions use the 5 kHz deviation FM standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try using the wider filter. Handheld transceivers generally have a single wide filter fitted as standard and you should get good results outdoors using just a 1/4 wave whip antenna.

ISS SSTV links for tracking and decoding Apps

You can receive the SSTV transmissions by using an Online Radio (WebSDR) and the MMSSTV software:

AMSAT-UK FUNcube Mission Patch Rev4 20100609

AMSAT-UK FUNcube Mission Patch

In space, satellites can be found. A recent development in this area are the “CubeSat” satellites.

Normal satellites typically have a size ranging from that of a washing machine to a small truck.

CubeSats have the size of a milk-carton!

This challenge focuses on the FUNcube-1 (AO-73) CubeSat satellite. During the JOTA-JOTI (October 19-21) a special, coded, message will be transmitted. This message can be received with a simple 2m handheld antenna, e.g. HB9CV, a small yagi or even a vertical, and a SDR-dongle or any SSB radio for 2m. The data is sent by the satellite on its telemetry channel of 145.935 MHz (1200bd BPSK modulated). You will need to set your receiver to Upper Side Band (USB). If you use a FUNcube dongle, you can directly receive the satellite.

The message is coded using the Enigma cipher machine. The deciphering key and Enigma settings can be obtained by answering the questions below.

The message sent by the satellite follows the following format: JOTA JOTI START coded message STOP

Your deciphered message can be mailed to: JJ.Satellite.Challenge (at) kitbuilding.org ( (at)=@)

The mail should contain your name, age, country and Scout group name and the correct answer!

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

If you have any pictures of the reception of the satellite with your group, this would also be highly appreciated, we would love to see how you did it!

If your answer is right and mailed before the 1st of November 2018, you will participate in a raffle.

The winner will get some products from www.kitbuilding.org

As you will know, AO73/FUNcube-1 has been in full sunlight for over one month and has been transmitting continuously high power telemetry for most of that time. This has now been changed to full time amateur mode so the transponder is once again available. With the more stable on board temperatures being experienced, this means that the transponder frequencies are also now more stable. We expect to leave it in this mode for some weeks so that the team can determine whether or not the currents flowing from the solar panels are having any noticeable effect on the spin period.


The FUNcube-2 transponder on EO-88/UKube-1 continues to be in full time transponder mode. There are occasional breaks in service for a few seconds when the OBC reboots and the other onboard transmitter sends its CW beacon.

FUNcube-3 on Nayif-1

EO88/Nayif-1 continues to perform nominally with high power telemetry when in sunlight and amateur mode when in eclipse.

With their slightly different orbital characteristics it is useful that AO73 is now the early bird, EO88 comes over in the mid morning and UKube provides coverage in the afternoon.

We have been suffering from some network issues in relation to uploading the telemetry from the Dashboards to the Data Warehouse over the past couple of weeks. Apologies for this, but hopefully everything is now stable again. ie fingers are still crossed. Thank you for all the telemetry that you upload.

Like many other teams, we are presently waiting for the next Space-X launch from Vandenberg which is expected to be carrying a number of new amateur payloads, These will provide additional transponder and STEM capabilities for the amateur satellite service. Exciting times ahead.
