In November the FUNcube-1 CubeSat will have been in orbit for 6 years and the FUNcube team are now soliciting suggestions for the next satellite

The team are looking for suggestions for:
• Conformation of the satellite (2U / 3U)
• Orbit (LEO / MEO)
• STEM Outreach
• Amateur Radio Payloads
• Research Payloads

Please email your ideas to:
funcube-next <at> funcube.org.uk

The topic will be discussed during the AMSAT-UK Colloquium on Sunday 13th October 2019 https://amsat-uk.org/colloquium/

Threat to Amateur Radio 23cm band

Galileo LogoA joint paper by France, Lithuania, Malta, Slovenia and The Netherlands for the CEPT CPG meeting in Ankara, August 26-30, attacks the continued use by Radio Amateurs of our 1240-1300 MHz band.

This is the final CEPT CPG meeting in preparation for the ITU World Radiocommunication Conference 2019 (WRC-19) to be held in Sharm el-Sheikh, Egypt, October 28 to November 22. This conference will define the Agenda Items for WRC-23.

Paper AI10 – Proposal on AS-RNSS says:

Galileo is close to full operational capability and its E6 signals in the band 1260-1300 MHz will support new services such as the free-to-use Galileo High Accuracy Service, and also robust authentication, expected to be used by a variety of applications including autonomous vehicles and the Internet of Things (IoT).

Several cases of interference to Galileo E6 receivers from amateur service emissions have occurred in the recent past, sometimes at significant distance, and have taken several hours or even days to be eliminated. There is therefore a serious concern that as Galileo E6 receivers are deployed and used more widely, cases of interference from amateur stations will rapidly grow in number.

A WRC-23 agenda item is necessary to address this issue because:

1. Unregulated use of the band 1240-1300 MHz by the amateur service is a serious source of harmful interference to RNSS receivers. This is demonstrated by experience.

2. The number of Galileo receivers in 1260-1300 MHz will increase dramatically, and interference cases will multiply if not addressed timely.

3. Galileo and other RNSS systems will deploy at global scale, and interference scenario between amateur emissions and RNSS receivers include cross-border cases. The issue is therefore of international nature and is to be addressed in the ITU framework.

4. Galileo is a major European asset, and a decision at WRC-23 is essential to be compatible with the roadmap of deployment of Galileo receivers in this band.

QO-100 geostationary satellite talk at Hamfest 2019

QO-100 talk by Paul M0EYT at Hamfest 2019

QO-100 talk by Paul M0EYT at Hamfest 2019

Paul Marsh M0EYT gave a presentation titled ‘All you need to know to get going on Es’hail-2 / QO-100 geostationary satellite’ at Hamfest 2019 in Dorset on Sunday, August 11.

The 50 minute talk covered satellite information, software, hardware, dish alignment and was followed by a question and answer session.

The talk proved to be very popular and attracted a large audience.

Paul has made available a PDF copy of the slides and you can download it here.

AMSAT-CE working on CESAR-1 FM transponder satellite

AMSAT-CE LogoThe Radio Club de Chile has announced the reactivation of the AMSAT-CE Foundation.

The Government of Chile has announced a plan to renew the Chilean Air Force Fasat Charlie satellite, along with promoting the construction of several micro and nano satellites.

This motivated the AMSAT-CE Foundation to propose that the CESAR-1 project of Chilean radio amateurs can be reactivated, modernized and completed, as part of the government plan.

Radio Club de Chile has supported AMSAT-CE since its begining and the Vice-President of Radio Club of Chile, José Tijoux CE3BCO, has just joined the Board of Directors of AMSAT-CE continuing and strengthening the space activity of Chilean radio amateurs .

The AMSAT-CE Foundation was created in 1993 and its first project is CESAR-1 which stands for CE (Chile) Satellite of Radiocommunication.

AMSAT-CE is designing and building five satellites, to be used by radio amateurs around the world, which will allow a series of scientific experiments in the field of digital communications, as well as gravimetric and orbitgraphic studies.

Of these five satellites, one will be the engineering prototype, three will be flight units, and the remaining one will be used to check or replicate on the ground the operation of the units that are in space.

The CESAR-1 satellite will be a  23 cm cube with a mass of about 12 kg and is planned to have five main experiments:

• A real-time digital transponder (Digipeater) using AX.25 at 9,600 kbps

• An electronic message box (Store and Forward) using AX.25 at 9.6 kbps)

• A 145 MHZ to 436 MHz band FM transponder

• A link to two terrestrial repeaters that will enable low power stations operating on 147 MHz FM to access the satellite

• An on-board GPS receiver, which will collect information for gravimetric and orbitgraphic research.

The orbit of CESAR-1 will be low, polar and heliosynchronous (about 800 km high).

High school students in Brazil building QO-100 ground station

Students at Colégio Embraer Casimiro Montenegro Filho

Students at Colégio Embraer Casimiro Montenegro Filho

High school students in Brazil are building a ground station for the amateur radio transponder on the QO-100 geostationary satellite as part of a STEM education project.

A group of eight students, from Colégio Embraer Casimiro Montenegro Filho in Botucatu state of São Paulo, are participating in all steps of the project with the help of teachers and amateur radio volunteers from LABRE/AMSAT-BR (Edson PY2SDR, Demilson PY2UEP, José PU2MJR).

The station consists of a 1.2m offset dish antenna, an Amiko L-104 LNBF, a home-made bias-t, a RTL-SDR receiver and SDRsharp software running on a dedicated computer. During the project students were exposed to several STEM topics related to radio communications, antennas, software defined radios, geostationary orbits as well as hand-on activities during the station assembly and configuration.

The students were able to successfully receive test transmissions in morse code kindly made by Roland PY4ZBZ and Fábio PY4AJ. The next step of the project is to introduce digital communication concepts, decode the BPSK engineering beacon and finally to add transmission capability to the station. In the near future, besides making contacts with other stations on QO-100, the students would also very much like to contact other schools and students in the QO-100 footprint.

Iceland’s IRA buys Qatar Oscar 100 and APRS equipment

Es'hail-2 Qatar-OSCAR-100The Board of Directors of Iceland’s nation amateur radio society, the IRA, has authorized the purchase of equipment to operate via the amateur radio transponder on the QO-100 (Es’hail 2) geostationary satellite.

A translation of the IRA post reads:

The Board of Directors of ÍRA recently agreed to authorize the Fund to purchase the following equipment from Microsat in Poland:

• Microsat WX3in1 Mini APRS Advanced Digipeater / I-gate (2 pcs.)
• PLXDigi – APRS Digipeater (2 pcs.)

Guðmundur Sigurðsson, TF3GS, submitted a request to the company on the APRS group. He says the equipment will seal the system and increase the quality and usability of the system, including utilizing the Motorola GM-300 terminal, which recently received eight such stations. The installation includes, among other things, installation of I-gate in Akureyri and Digipeater on Þorbjörn near Grindavík.

At the same meeting, the acquisition of QO-100 transverter from PE1CMO in the Netherlands was further authorized; “A complete transverter with a 25 MHz reference oscillator for the LNB, a downlink converter from 739 to 432 MHz and an upconverter from 432 to 2400 MHz, double filtered and a 20 Watt amplifier.” Ari Þórólfur Jóhannesson, TF1A, VHF manager of the company, negotiated a discount price for the company at Ham Radio show 2019 in Friedrichshafen.

The APRS equipment costs about 45 thous. krónur and the Oscar-100 equipment by 118 thous. krónur (with accessories and connectors). The stated price includes transportation and charges in Iceland.
