Qatar OSCAR-100 is the first geostationary amateur radio transponder, a joint project between the Qatar Satellite Company (Es’hailSat), the Qatar Amateur Radio Society (QARS), and AMSAT Deutschland (AMSAT-DL) which provided the technical lead.

OSCAR-100 is hosted on Es’hail-2, a Broadcast Transponder Satellite owned by the Es’hailSat Qatar Satellite Company, the satellite is now in geostationary orbit at 25.9° E.

More information on the OSCAR-100 project can be found at AMSAT-DL Phase 4-A

In co-operation with AMSAT-UK, the British Amateur Television Club will be operating a WebSDR for the narrowband segment, and a Spectrum Viewer for the wideband (DATV) segment.

Goonhilly Earth Station is supporting the project, providing hosting for the Ground Station facility at their world-famous site in Cornwall, UK.

Es’hail-2 / QO-100 Teleport Inauguration Day February 14

At Es'hailSat Qatar - Credit AMSAT-DLFollowing the successful launch of Es’hail-2, the new Es’hailSat teleport will be inaugurated on February 14, 2019.

AMSAT-DL report:

This will also be the occasion to officially put the two amateur radio transponders of Qatar OSCAR-100, the first geostationary P4-A satellite from Qatar, into operation. The opening ceremony will be held by His Excellency Abdullah bin Hamad Al Attiyah, former Deputy Prime Minister of Qatar. A71AU is also the chairman of the Qatar Amateur Radio Society (QARS) and initiator of the first Qatari amateur radio satellite.

A team of the P4-A team of AMSAT-DL, consisting of the chairman Peter Gülzow DB2OS, Achim Vollhardt DH2VA and Thomas Kleffel DG5NGI, is on its way to Qatar to set up and commission the P4-A ground segment at the ground station of Es’hailSat. In addition to LEILA and the DVB-S2 DATV system, this also includes a club station for SSB radio operation under the callsign A71A. A backup station is installed at QARS in Doha. The ground station of the AMSAT-DL at the observatory Bochum is also ready for reception and transmission. Later, radio operation via Qatar-OSCAR 100 will also be carried out here under the callsign DL50AMSAT.

During commissioning, we expressly request that you refrain from any transmission attempts!

The SCC in Qatar, as well as Bochum in Germany, are carrying out some tests to measure both transponders and to calibrate the ground systems.

Please also note the beacons sent in the NB transponder. On the DATV beacon of the WB Transponder a video of Es’hail-2 will be broadcast in an endless loop in DVB-S2 format on the opening day.

Furthermore, the rules of the game, as defined in the Operating Guidelines for the Narrowband transponder and Wideband transponder are formulated. Please observe the band boundaries of the NB transponder as defined by the upper and lower beacon! A later adaptation and possible extension upwards may be considered after first experiments.

We appeal to patience and to the Ham Spirit: any disruptions during commissioning and on the opening day could result in further postponements of the official release.

On November 15, 2018, Es’hail-2/P4A was launched on a Falcon 9 launch vehicle from the Cape Canaveral Air Force Station Space Launch Complex 40 in Florida.

Es’hail-2/P4A was developed jointly by QARS (Qatar Amateur Radio Society) and Es’hailSat (the Qatar Satellite Company), with AMSAT-DL as the technical lead, and is the first geostationary amateur radio payload. The satellite has reached its final position at 25.9 °E, and the narrow and wideband transponders were successfully tested on December 23rd. The transponders are expected to be opened for general use in February 2019.

At the request of AMSAT Deutschland e.V., QARS, and Es’hailSat, AMSAT hereby designates Es’hail-2/P4A as Qatar-OSCAR 100 (QO-100). May the 100th OSCAR satellite be the guide star to future amateur radio satellites and payloads to geostationary orbit and beyond.

Consultation on Amateur Satellite Service – Your input needed

EO-79 and EO-80 – Image Credit ISIS

Satellite / nanosatellite project managers often wish to use amateur radio frequencies for educational and outreach purposes. The amateur radio community thus offers them a tremendous potential for monitoring their fragile conception. They often ask what kind of amateur radio experience would be interesting onboard a CubeSat or what services they could provide with their communications systems. The answer can be simple: a transponder, but these designers would like to bring novelty and innovation.

In order to provide more factual input, AMSAT-F has decided to launch an English Language Online Survey to find out what you do and would like to do as a satellite activity, what you expect from satellite designers and what you can bring to them. *The synthesis of these results will be presented at the second* AMSAT-F meetings « Rencontre spatiale radioamateur » on March 9 and 10, 2019 in Nanterre (France).

Do not hesitate, give your opinion by completing the questionnaire via the link : https://framaforms.org/amsat-francophone-survey-1548716436

The survey is in English but hosted on French server. Few guideline could be in French.

NEXUS CubeSat designated as Fuji-OSCAR 99

NEXUS PosterOn January 18, 2019, NEXUS was launched on an Epsilon launch vehicle from the JAXA Uchinoura Space Center in Japan.

NEXUS (NExt generation X Unique Satellite) is a satellite developed jointly by Nihon University College of Science and Technology and the Japan Amateur Satellite Association (JAMSAT).

NEXUS demonstrates several new amateur satellite communication technologies, and includes a mode V/u linear transponder.

Telemetry has been received and decoded around the world since the launch, and the transponder was successfully tested on January 26th.

More information may be found at
http://sat.aero.cst.nihon-u.ac.jp/nexus/E0_Top.html

At the request of the Nihon University College of Science and Technology and JAMSAT, AMSAT hereby designates NEXUS as Fuji-OSCAR 99 (FO-99). We congratulate the owners and operators of FO-99, thank them for their contribution to the amateur satellite community, and wish them continued success on this and future projects.

AMSAT SA 2 m / 70 cm dual-band Yagi antenna is now available

AMSAT-SA Dual-band 145/435 MHz Yagi

AMSAT-SA Dual-band 145/435 MHz Yagi

AMSAT SA have made available a new dual-band 145/435 MHz Yagi antenna for amateur satellite operation.

The Yagi has a unique element called an ‘Open Sleeve’ which is a director very close to the driven element. The driven element is sized for 2 metres. When operating on 70 cm the ‘Open Sleeve’ acts as part of the driven element on 70 cm (Third harmonic of 2 m).

The AMSAT SA version is based on a design by Martin Steyer, DK7ZB with modifications by the late Larry Brown, WB5CXC. The first South African version was a collaboration between Guy Eales, ZS6GUY and Gary Immelman, ZS6YI. It was developed for YOTA 2018 where young people successfully used the antenna operating satellites using hand-held transceivers.

The mechanical structure of the AMSAT SA version was redesigned by Gary, ZS6YI. A choke around the boom was added to isolate the antenna from the coax and reduce the effect human contact has on the antenna. A handle was added on the boom end which makes it more comfortable to hold and further isolates the antenna from the handler.

The antenna is plug and play. No tools are needed except for soldering on a connector to suit the application. It comes complete in a carry bag with full instructions. This antenna can be assembled and dissembled in minutes. For more details and how to order, visit http://www.amsatsa.org.za/

SARL and AMSAT SA members get a discount.
