University students learn about Amateur Radio Satellites

Celebrating Engineering Day Workshop with Rajesh Vagadia VU2EXPIn India on 15 Sep 2022, on the occasion of National Engineering Day, an excellent Workshop titled “Fascinating World of Ham Radio & Amateur Radio Satellites” was conducted by AMSAT-INDIA’s Regional Coordinator Rajesh Vagadia VU2EXP at reputed Marwadi University Rajkot (Gujarat) INDIA.

It was half day (10:00 AM to 02:00 PM IST) interactive workshop full of presentations, Audio Visual Documentary, Practical Demos, Q & A sessions and Radio stuff Exhibition with live operation.

There were 80 B.Tech students participated from ICT Dept + MU’s Student Satellite Project team. Yes Marwadi University has announced to build a Student Satellite and to be launched by ISRO!

Our ham team includes YL Sakshi Vagadia VU3EXP & YL Shyama Vagadia VU3WHG, both member extended great support to setup VHF station, organise & display Radio Stuff and assisting in practical demos including SSTV, Digital & VHF FM Demo with groups! Btw Shyama VU3WHG also remains one of the student coordinator of this event as well as Team member of Student Satellite Project.

All participants gained knowledge on broad spectrum of topics from CW to Cube Satellites! In first session Radio Fundamentals, operating protocols, radio jargons, licensing procedure etc were covered. In second session participants were briefed with various Ham radio events like FD, Hilltop, Light House activation, POTA, IOTA, EME, Satellite tracking, SatCom, High Altitude Balloon tracking, ARISS SSTV & Student outreach program which gives exposure to gain knowledge & develop skills from outside radio Shack activities also!

Lots of fruitful discussion happens during workshop and students were satisfied with all of their queries.

In workshop we had gracious presence of Shri Naresh Jadeja (Registrar), Dr. R. Sridaran (Dean), Dr. Jaypalsinh (MCA Dept), and Dr. Shobhit Patel (Researcher). We also get positive response from Marwadi University authorities to be engaged with AMSAT-INDIA to conduct more programs & projects in upcoming period for benefit of student community.

We also thank to Shri C. D. Parmar Sir (HOD ICT) and Program Coordinator Prof Mitesh Solanki for all the great support provided to make this workshop successful.

I am glad to notice this Ham workshop created a Ham buzz in the Marwadi University campus. For me too it was great honor to present & share my best knowledge amongst budding engineers on the occasion of Engineering Day!

Thank you

23cm Band and RNSS Coexistence September Update

RNSS Satellites Oribiting EarthAs the WRC-23 approaches so the studies regarding AI9.1b (23cm and RNSS) are working towards conclusions. However the IARU is not content that all the operational aspects of the amateur service usage of the 1240-1300 MHz band are being properly considered to develop an acceptable compromise for all concerned parties.

Having been deeply involved in the regulatory work described below it is the opinion of the IARU that for many national authorities the 23cm band WRC23 agenda item 9.1b topic has a very low priority. Many are taking a “generic” stance stating their support for studies without considering the detail of the work or how it is moving forward. Therefore the IARU requests that Member Societies urgently put this issue on the agenda with their national authorities to discuss the views laid out below.

The IARU view is that the potential for widespread or persistent interference to the radio-navigation satellite service (RNSS) from amateur service transmitters is over-stated. However, recognising the regulatory situation, the IARU and the amateur community are ready to accommodate any technical or operational measures deemed necessary on the amateur services so long as they are proportionate, reasonable and evidence based.

The IARU believes that a careful compromise needs to be found in the outcome of the work and the execution of WRC-23 agenda item 9.1b, that properly takes account of the low likelihood of interference events occurring whilst allowing both the amateur services and the RNSS to develop in the band.

The IARU stresses the opportunity that the higher frequency amateur service bands enable for technical skills development for researching and experiencing radio propagation effects. The 1240 – 1300 MHz band is important for the amateur radio service, being the lowest allocation for radio amateurs on which typical microwave propagation can be experienced. Access to these frequencies is facilitated by commercially available equipment and provides a ‘bridge’ building motivation to become involved in more specialized higher frequency microwave and millimeter wave operations providing the self-training which is at the heart of amateur radio.

AMSAT-UK Colloquium 2022

Kents Hill Park Conference Centre Milton Keynes MK7 6BZ

Kents Hill Park Conference Centre Milton Keynes MK7 6BZ

AMSAT-UK is very happy to announce the 2022 AMSAT-UK International Space Colloquium will be held as part of the RSGB Convention on October 8-9 at the Kents Hill Park Conference Centre, Timbold Drive, Milton Keynes, MK7 6BZ.

Booking for the RSGB Convention which includes the AMSAT-UK Colloquium is at
https://rsgb.org/main/about-us/rsgb-convention/
Note if you want to attend the AMSAT-UK Dinner on Saturday evening (see below) you shouldn’t book the RSGB Convention Saturday Dinner, they are separate and in different venues.

We will be running our own Gala Dinner on Saturday evening at the nearby hotel Delta by Marriott . This is a separate event from the dinner run by the RSGB which will be held in the Kents Hill conference centre. You MUST book in advance for our Gala Dinner, and you can do this at the AMSAT-UK on-line shop here

If you have not been to Kents Hill Park before, it is very close to the M1 motorway and is near to Bletchley Park, where RSGB members have free entry. For overseas visitors it is convenient for planes to London Luton Airport (30-minute taxi ride) and also London Gatwick and Birmingham airports, both of which have direct train connections to Bletchley and/or Milton Keynes stations. These stations are approximately 10 minutes away by taxi.

The weekend event attracts an international audience that ranges from those involved in building and operating Amateur Radio satellites to beginners who wish to find out more about this fascinating branch of the hobby.

We will be including a roundup of a number of new live and potential spacecraft projects that are under investigation and/or development.

Plus all the usual networking opportunities, the gala dinner and auction/raffle.

AMSAT-EA satellites to launch

AMSAT-EA GENESIS Satellites

AMSAT-EA GENESIS Satellites

Felix EA4GQS reports Spain’s latest amateur radio satellites to launch will be GENESIS-G and GENESIS-J on September 11

The AMSAT Bulletin Board post says:

This is to confirm that the launch of our new GENESIS-G and GENESIS-J satellites with Firefly will take place, if all goes well, on September 11, with the launch window starting at 3 PM Pacific Time (22h GMT), from Vanderberg. The expected orbit altitude is 300 km with an inclination of 137 degrees.

As many of you know, this will be the second attempt of Firefly to reach orbit after the first attempt made in September 2021 and which had to be aborted after two minutes of flight, causing our previous GENESIS-N and GENESIS-L to be lost, among others.

These new GENESIS have a more powerful on-board computer than their predecessors and updated software that allows FM voice repeater functionality, AFSK/FSK non-regenerative repeater up to 2400 bps, FSK regenerative repeater up to 50 bps, CW, digitized voice pre-recorded FM and FSK telemetry at 50 bps. The correct retransmission of AX25 / APRS frames over FM up to 2400 bps has been verified in the laboratory.

A small drawback we still have is the antenna deployment mechanism, that is the first version that was made and requires a plenty charged battery. The satellites have been stored for several months, so it is a weak point. Hopefully it will work.

These satellites also have the names of ASTROLAND-1 and ASTROLAND-2 to say thanks to the sponsorship of the project by the Astroland Planetary Agency. We also thank the private companies and Universities that helped in the project.

As on the previous occasion, two experimental propellants are flown, although this time they are from the Madrid company IENAI Space and, unlike the previous GENESIS mission, they use a liquid ionic fuel. Only the one from GENESIS-J is functional. The one from GENESIS-G carries the electronics but without the fuel.

The frequencies coordinated with IARU are the following:

GENESIS-G/ASTROLAND-1
145.875 MHz uplink, Modes: FM voice (no subtone) and FSK 50 bps, AFSK, AX.25, APRS 1200 / 2400 bps
436.888 MHz downlink, Modes: FM voice, CW, FSK 50 bps, FM voice beacon with AM2SAT callsign

GENESIS-J/ASTROLAND-2
145.925 MHz uplink, Modes: FM voice (no subtone) and FSK 50 bps, AFSK, AX.25, APRS 1200 / 2400 bps
436.666 MHz downlink, Modes: FM voice, CW FSK 50 bps, SSTV Robot 36, FM voice beacon with AM3SAT callsign

We encourage all of you to try to receive their first transmissions once the first keplerians are available.

This flight will be streamed by Everyday Astronaut: https://everydayastronaut.com/
