The AMSAT-UK International Space Colloquium is being held in conjunction with the RSGB Convention in Milton Keynes. One of the highlights will be a presentation by Naomi Kurahara JE6GXN CEO of Infostellar Inc. at 1600 BST (1500 GMT) on Saturday, October 13 which will be streamed live to a global audience.

She will be giving a presentation about her philosophy for shared ground station operation for Low Earth Orbit (LEO) satellites such as CubeSats and Nanosats.

StellarStation Amateur provides free Launch and Early Operation (LEOP) support for amateur UHF band satellites providing access to telemetry data using their worldwide ground station network.

Update on Es’hail-2 given at AMSAT-DL symposium

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 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.

FCC 24 and 47 GHz 5G spectrum auction

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.
