The article quotes President of AMSAT DL, Peter Gülzow DB2OS, and describes the transponders planned for the Es’Hail-2 satellite, expected to be launched in the 3rd quarter of 2017 into a geostationary orbit at 26 degrees East.

Also mentioned is a project to build a transponder for a US satellite which could be in a geosynchronous orbit around 74 degrees West.

D-STAR satellite to launch from Kourou

The ESA Education Office Fly Your Satellite! (FYS) programme is designed to train the next generation of aerospace professionals. Three chosen student teams have each developed 1U CubeSats carrying amateur radio payloads which are expected to launch at 2102 UT on Monday, April 25, 2016 on a Russian Soyuz-STA Fregat-M rocket from Kourou in South America into a 453 by 644 km 98.2 degree inclination orbit.

The satellites designed and built by the student teams, arrived in South America on Friday, March 25. Upon arrival, they were given a security escort from the airport to the Guiana Space Centre, near Kourou. The student teams arrived on March 28.

The satellites themselves are CubeSats. This class of small satellites have helped revolutionise access to space. Made of standard components, as the name suggests they come in modular dimensions of just 10x10x10cm in size.

On March 30 the students removed the so-called Remove Before Flight pins and successfully verified that the CubeSats were ready for launch. Afterwards, the lateral access ports of the P-POD were put back in place.  The next time the students will have contact with their respective CubeSats will be through the communication link after the satellites are deployed into orbit. The next activities consist in completing the application of a special thermal-optical tape on the outside of the P-POD, which will ensure the unpowered CubeSats are shielded from extreme thermal radiation during the launch phase. Finally, the planning for the next weeks will consist in integrating the P-POD with the rest of the launcher.

OUFTI-1 from the University of Liege, Belgium, will be the first satellite to carry a D-STAR Digital Voice transponder. The article ‘D-STAR digital amateur communications in space with OUFTI-1 CubeSat’ by Jonathan Pisane ON7JPD, Amandine Denis ON4EYA and Jacques Verly ON9CWD can be seen in the June 2013 Edition 202 of the AMSAT-UK publication OSCAR News.

e-st@r-II from the Polytechnic of Turin, Italy, will demonstrate an attitude control system using measurements of the Earth’s magnetic field; and AAUSAT4 from the University of Aalborg, Denmark, will operate an automated ocean vessel identification system.

The Derby High School to speak to ISS

The Bury Times reports The Derby High School GB1DHS will be one of only two schools in the North West to hold an amateur radio contact with UK astronaut Tim Peake GB1SS. The contact is scheduled for Monday, April 25 at 12:02 GMT (1:02 pm BST).

The newspaper says: The call from The Derby High School to the International Space Station will take place on the week commencing April 25, but because the link is dependent on the exact orbit of the ISS and the crew schedules, the exact dates and times for possible calls will not be known until around 10 days before the link up is scheduled.

The Derby was selected to host a call after applying to take part in the Amateur Radio competition, a collaboration between the UK Space Agency, the Radio Society of Great Britain (RSGB) and the European Space Agency (ESA).

FUNcube transponder on EO-79 active

EO-79 and EO-80 – Image Credit ISIS

On March 25, 2016, the EO-79 SSB/CW transponder was activated and will be available during Easter.

The FUNcube transponder subsystem on QB50p1 (EO-79) had been provided by AMSAT-UK and AMSAT-NL and is a similar subsystem as on FUNcube-1, but without the telemetry downlink circuitry.

The current software running on EO-79 does experience occasional reboots. When these reboots happen, the transponder is automatically turned off and will have to be turned back on by a command station. The FUNcube team has selected a few command stations to do so, but be advised the transponder may be off.

TLEs:
AMSAT keps name: EO-79
Celestrak keps Name: QB50P1
Celestrak file: cubesat.txt
NORAD #    40025
COSPAR designator    2014-033-R

Frequencies:
Uplink: 435.035-435.065 MHz LSB
Downlink: 145.935-145.965 MHz USB

EO-79 has been set to only beacon the normal AX.25 beacon every 30 seconds instead of 10 seconds. The beacon frequency is 145.815 MHz and consists of AX.25 frames on BPSK. more details about the downlink can be found on the ISIS HAM page at http://isispace.nl/HAM/qb50p.html

Just like FUNcube-1, the crystal oscillator circuits exhibit drift with temperature. This means manual tuning will probably work best.

Lastly, the commanding team availability will be limited over Easter, so please report the transponder being on or off on the status page of AMSAT: http://www.amsat.org/status/
It does not appear in the table, but it does in the reporting drop-down.

73 and have FUN

UK student balloon flies around the world

On Monday, March 21, 2016 the UBSEDS14 balloon, launched by University of Bristol students, completed its circumnavigation of the Northern Hemisphere.

The University of Bristol Students for the Exploration and Development of Space (UBSEDS) launched their balloon on Monday, March 8. Powered by a single AA Lithium Energiser Battery (LR91).

During the flight at an altitude of about 11,500m the balloon has been transmitting telemetry data at 4 minute intervals using 5 dBm output of Contestia 16/1000 on 434.600 MHz USB. Each telemetry packet is preceded by 10 seconds of 1Hz pips for manual alignment and a RSID tone for automatic alignment with suitable software. Additionally the payload has the capability for 144 MHz APRS.

The balloon has a diameter of 1.5m and the payload weighs just 21.3 grams. Despite the weight constraints the team have managed to employ sophisticated Geofencing technology to prevent the balloon transmitting when over certain countries and also to select different APRS frequencies depending on the territory being overflown.
