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:

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!

LO-94 spacecraft signal decoded after bouncing off Moon

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.

Cassini-Huygens: Odyssey to Saturn and Titan – Sunday Oct 14

Professor David Southwood

Professor David Southwood

At 10:45am on Sunday, October 14, the Chair of the UK Space Agency Steering Board Professor David Southwood will give a presentation on the Cassini-Huygens mission to the AMSAT-UK International Space Colloquium in Milton Keynes.

More than 35 years ago, a small group of scientists in Europe met with American counterparts to discuss what might be done to explore jointly the outer planets – in particular Saturn, its rings and moons.

At the time, Europe did not have plans to explore the solar system at all. Indeed, many wanted to keep it that way. Nonetheless, in what seems now a very short time, 6 years later, it was agreed that Europe and the US would jointly perform a grand mission, Cassini-Huygens to Saturn and its major moon, Titan with Europe building Huygens, the Titan lander.

In 2017 almost 20 years after Cassini-Huygens was launched to Saturn the programme finally ended with the Cassini mothership deliberately diving into the Saturn atmosphere. The history of the programme and some of its highs and lows will be outlined.

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

The Guardian interviewed radio amateur Dr. Chris Bridges 2E0OBC for their story on the growing UK space industry.

Chris 2E0OBC worked on the Surrey Space Centre’s STRaND-1 spacecraft which carries an amateur radio payload. The newspaper also interviewed Steve Greenland, Senior Systems Engineer at Clyde Space, who worked on the UKube-1 spacecraft which carries the FUNcube-2 amateur radio transponder.

Shin’en2 spacecraft designated as Fuji Oscar 82

William A. (Bill) Tynan, W3XO, OSCAR Number Administrator has conferred on Shin’en2 the designation Fuji OSCAR-82 or FO-82.

Shin'en 2 (FO-82) also known as Abyss 2

Shin’en 2 (FO-82) also known as Abyss 2

In reply to Seiji Fukushima’s, JH6RTO, request for an OSCAR number, Bill said, “I along with all in AMSAT-NA and the world’s Amateur Radio satellite community congratulate you and all involved with Fuji OSCAR-82 and trust that it will fulfill all of its mission objectives. FO-82 joins an illustrious line of Fuji spacecraft built and launched by Japan.”

Shin’en2 is a 17 kg satellite measuring 490×490×475 mm built by students at Kagoshima University in Japan. The aims of the mission were:
• To establish communication technologies with a long range
• To establish a new technology of the ultra-light-weight satellite with UHF downlinks

The orbit is quite different from the previous satellites. Shin’en2 headed to a deep space orbit between Venus and Mars. The inclination is almost zero, which means it will stay in the Earth’s equatorial plane.

The distance from the Sun will be between 0.7 and 1.3 AU. An Astronomical Unit (AU) is 149,597,871 km.

Shin’en2 IARU coordinated frequencies listed as:
• 437.505 MHz CW beacon
• 437.385 MHz Telemetry

Shin’en2 launched in the 4th quarter of 2014 with another amateur radio satellite, ARTSAT2:DESPATCH, on a H-IIA rocket with the asteroid explorer Hayabusa 2 as the main payload.

Australian radio hams plan winged spacecraft

The WIA highlights an ABC news story about the spacecraft being developed by radio amateurs Robert Brand VK2URB and his 12-year-old son Jason VK2FJAB.

The WIA news report says:

An Australian man and his 12-year-old son are hoping to make history with the development of the smallest spacecraft able to re-enter Earth’s atmosphere and land safely.

Robert Brand VK2URB is the developer of the craft, named ThunderStruck, a small winged re-entry vehicle capable of leaving Earth’s orbit and flying around the solar system, at least as far as Mars or the near-Earth asteroids.

What makes ThunderStruck unique was that it could fly up and back for basic experiments without going into orbit or it could fly into orbit on board a rocket then re-enter, something that was not being done anywhere else.

Project ThunderStruck has the backing of Australian government bodies and universities and is on the cards to be a fully working spaceship in about five years.

Another unique aspect of Project ThunderStruck would be the involvement of Mr Brand’s 12-year-old son Jason VK2FJAB in the first phase of testing, scheduled for April, the transonic testing phase would attempt to test the 2.5-metre craft at speeds close to Mach 2, faster than the speed of sound.

Mr Brand said his son worked with him releasing and bringing back high-altitude balloons from the stratosphere and had considerable expertise in space technology, in spite of his young age.

Mr Brand said if the project came together it would be unique and give Australia a much-needed boost in space development
