Dax för ett nytt spännande projekt med amatörradio ombord på forskningssatelliter som skickas långt ut i rymden. De två amatörradiofarkosterna kommer att ha en elliptisk bana runt solen och resa till en bana mellan Venus och Mars . Lutningen (inclination) kommer att vara nästan noll , vilket innebär att satelliterna bör stanna i jordens ekvatorialplan.

ARTSAT2 har en 7 watts CW -sändare på 437,325 MHz och är också den första 3D-utskrivna skulptur som skickas ut i rymden .

Shin’en2 har en CW fyr på 437,505 MHz ( 0,1 watt ) och telemetri på 437,385 MHz ( 0,8 watt ) med användning av ett mode som Seiji JH6RTO beskriver som liknar WSJT men dock inte samma.

Mer information på AMSAT-UK.

COSMOS-2499 (2014-028E) sköts upp den 23 maj 2014 och är nu i en bana på 1,510.6 km X 1,158.8 km 82.4 degree. Dmitry Pashkov R4UAB har nu tagit emot signaler från satelliten på ungefär  435.465 MHz och 435.565 MHz (+/- Doppler). Den 30 november 2014 började satelliten identifiera sig själv som RS-47 på CW!

Satelliten är ett litet mysterium, den har ändrat sin bana flera gånger, vilket man kan läsa mer om på http://www.russianspaceweb.com/Cosmos-2499.html

Nu kan vi fortsätta följa satelliten som RS-47 på amatörradiobandet. Fler uppdateringar följer säkert.

Även FUNcube-1 – AO73 firar år. Inte lika många som Oscar 7 (40 år) utan ett år uppe. AO-73 har fungerat mycket bra och telemtrin tagits emot av hundratals lyssnare.

G3WGM har gjort en bra sammanfattning:

Hi Folks,

It seems amazing to us that FUNcube-1 – AO73, was launched nearly one year ago, in fact at 07:10 UTC on 21 Nov 2013. The very first signals were received by ZS1LS in South Africa at 07:37 UTC and he was even able to upload the resulting data to the Warehouse so the results could be seen immediately.

We are extremely  happy to say that, since then, the satellite has been performing very satisfactorily, the battery voltage doesn’t drop below 8 volts, and becomes fully charged within about 7 – 10 minutes after re-entering sunlight from eclipse.

Thus, on 21 Nov 2014, we will be celebrating the satellite’s first birthday. To mark the occasion, we will be activating the transponder earlier than normal – late on Thursday 20 Nov 2014, so that it will be available for use during the whole of Friday. So please make as many contacts as possible through the transponder during Friday, FUNcube’s actual birthday. You are invited to make a note of any stations worked on this day, or any other comments on the FUNcube Forum. Please use the existing “FUNcube-1’s Birthday” topic, under the Welcome heading. The URL of the Forum is http://forum.funcube.org.uk/index.php.

Please also remember the ’73 on 73′ competition which is kindly being organised by Paul Stoetzer N8HM. See http://amsat-uk.org/2014/08/18/73-on-73-award-announcement/ for more details.

We would like to take this opportunity of thanking all of our ‘users’, both those who download  telemetry and forwarding it to the warehouse, and of course, all users of the transponder. This telemetry data is invaluable, both as an educational resource and to enable us to see how the spacecraft systems are performing and surviving. So far we have collected almost 400MB of unique data via stations from all around the world.

Of course we are hoping that the satellite continues to function nominally for several  more  years to come even though we may never reach AO7’s record!
