FUNcube-1

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.

FUNcube-2

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.

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

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.

Peter Gülzow DB2OS President AMSAT-DL

AMSAT-DL President Peter Gülzow DB2OS reports on a new amateur radio satellite forum that aims to help newcomers become active on the satellites.

On the AMSAT Bulletin board (AMSAT-BB) he writes:

We have set up a new online forum at https://forum.amsat-dl.org/

Especially with the upcoming launch of P4-A/Es’hail-2 we want to offer a forum for extensive discussions.

Essentially this is a forum, where everyone can report on experiences and knowledge from operating satellites and thereby help other newly interested radio amateurs to become active and a member of our satellite community.

Of course all topics around amateur radio satellites and OSCAR’s should be discussed there, appropriate categories and forums were created. If necessary this can be extended at any time and on request.

We would be pleased if the new forum is well received and you register there with your callsign (if available) as your name.

Of course you can also look around as a “guest”.

Experienced users can also check in the settings for new entries and have them delivered by eMail if you wish so.

In this sense, have fun

Es’hail-2 coverage area

DARC reports on Saturday, September 29, the annual symposium of AMSAT-DL took place in the IUZ observatory Bochum.

The Google translation reads:

There were lectures on current amateur radio satellites and space projects. The focus was on the first geostationary amateur radio satellite Es’hail-2, whose launch is expected later this year, as well as the MEGINASAT project, the first CubeSat from a German grammar school.

The lecture series was opened by Thilo Elsner, DJ5YM, whose article gave an overview of the ESERO office Germany opened in Bochum on May 16. ESERO stands for “European Space Education Resource Office”. The aim of the initiative is to bring space travel in the context of STEM subjects exciting and innovative in the classroom. After a lengthy selection process, Bochum was chosen as the location for Germany. In cooperation with the Ruhr-Universität Bochum, the observatory Bochum, the AMSAT-DL and other partners are founding members of this educational and scientific consortium.

Afterwards, AMSAT-DL-President Peter Gülzow, DB2OS, and Achim Vollhardt, DH2VA, talked about the current status of Es’hail-2 (called AMSAT-intern P4-A), whose launch will start in the fourth quarter of 2018 according to operator Es’hailSat should be done. A concrete start date is still not available. Recently, the AMSAT-DL completed and finalized the individual components for the Es’hail-2 ground station in Doha / Qatar. “Last week we finished the work and made the equipment ready to ship,” reported DB2OS. The components will soon be installed in Qatar. Another facility will be back up at the Qatar Amateur Radio Society (QARS) in Doha. A third ground station will be installed at the AMSAT-DL in the Bochum observatory. Two transponders are available on the satellite for amateur radio: a narrowband and a broadband transponder to be used for DATV broadcasts. “We hope to be able to present live broadcasts in DATV at the next HAM RADIO from June 21 to 23, 2019,” said Gülzow optimistically.

How satellite radio can also contribute to the successful recruitment of youngsters was demonstrated by the MEGINASAT team headed by project leader Thomas Leister, DG2PU. The project originated from an ISS contact of the Megina Gymnasium Mayen in 2012 and a stratospheric balloon launch in 2016. Specifically, MEGINASAT is the first CubeSat from a German grammar school. The students Florian Jüngermann, Max von Wolff (Physics Bundessieger at Jugend forscht) and Max Schild presented the project and pursue ambitious goals: The CubeSat is to serve Earth observation and send its image data by light transmission to Earth. Also sponsorship funds in five-digit amount have already been collected, now the team is looking for only one.

The European Student Earth Orbiter (ESEO) satellite carries an 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.

FCC 24 and 47 GHz 5G spectrum auction

lør, 29/09/2018 - 20:41

The FCC has announced it is to make additional spectrum available for 5G services by auctioning spectrum that includes 24.25-24.45, 24.75-25.25 and 47.2-48.2 GHz.

The RSGB joint response to the 2018 Ofcom WRC-19 consultation expressed concern about the use of this spectrum.

“the RSGB does not support the allocation of the range 24.25 – 25.25 GHz to the mobile service in Region 1 and its subsequent identification for IMT. The amateur and amateur-satellite services have a global primary allocation in 24 – 24.05 GHz and the out of band emissions from a mass deployment of mobile broadband systems operating in very wide channels in adjacent frequencies will appear as interfering noise in the primary amateur allocation. An identification that starts at 25.25 GHz could mitigate this difficulty.”

“We would not wish to see adjacent out-of-band emissions causing interference to our primary amateur and amateur-satellite service allocations at 24.0-24.05 and 47.0-47.2 GHz”

The Hindu newspaper interviews radio amateur Gurudatta Panda VU3GDP about the ExseedSat CubeSat built by an eight-person team at the Hyderabad-based Exseed Space Private Limited that was co-founded by Ashhar Farhan VU2ESE.

ExseedSat carries an amateur radio FM transponder and APRS digipeater and is expected to be launched by SpaceX towards the end of 2018.

“This satellite will serve the ham or the amateur radio community. As a result, it will be of great help during natural calamities, when conventional communication services get disrupted,” Gurudatta Panda VU3GDP said.

After the launch, this artificial satellite will be on a polar orbit with two passes over India everyday. The public will be able to receive this artificial satellite’s beacon on 145.900 MHz FM using a TV tuner and USB dongle, Mr. Panda added.

He said the eight-member team involved in construction of the small private satellite involved four technocrats and four managerial staff members.

He and Exseed Space co-founder Ashhar Farhan VU2ESE were the communication engineers who played a key role in building the satellite.

AO73/FUNcube-1 is entering a further period of full sunlight

søn, 26/08/2018 - 23:58

AO-73 Spin PeriodAO73/FUNcube-1 has been in space for almost five years and the original Sun Synchronous Orbit has now changed slightly such that the spacecraft will no longer be in eclipse for 35 mins every orbit.

The eclipse period has already reduced and will again become zero on September 8, 2018. This means that our usual autonomous switching between transponder on in eclipse and high-power telemetry when in sunlight will no longer be effective!

This schedule was originally planned to provide a very strong telemetry signal for schools to use during daylight hours and for amateur operation at night (and also at weekends and over holidays).

We have already experienced a short period of full sunlight but this time it looks like the spacecraft will be in this situation for more than eight months until sometime in April next year.

In addition to the additional thermal effect that will occur during this period, we also expect that the spin rate will increase. The reason for this effect is not yet fully understood but may be related to the amount of current flowing from the solar panels to the spacecraft bus being sufficient to cause a torque effect with the earth’s magnetic field.

We have therefore decided to have AO73/FUNcube-1 initially operate for alternate periods of one week in either safe or educational modes. This should enable us to evaluate whether the currents do affect the spin rate. Safe mode provides low power telemetry and education mode the usual high power telemetry. It will also enable an analysis to see whether the satellite becomes hotter or cooler in each mode.

This schedule may be changed in light of experience and we will update everyone on such changes via the AMSAT-BB in the usual way http://www.amsat.org/pipermail/amsat-bb/

The new schedule will be put into effect on Friday, August 31, 2018.

This will be a new experience for the spacecraft so the capture of the largest possible amount of telemetry remains an important tool for the team to have. We are very grateful to everyone who continues to upload the telemetry they have received to the Data Warehouse. It is invaluable.

In addition to AO73/FUNcube-1, the FUNcube-2 transponder on UKube-1 remains operational and EO88/Nayif-1 continues to operate autonomously with the transponder on when in eclipse and high- power telemetry in sunlight.
