Many folks would like to see us back on the Moon and developing its resources.

Good day - Radio "amateurs" detect Voyager 1 signal

Thanks for the heads up from Larry Klaes.

Speak about being able for Amateur Radio Hams to bounce signals off the Moon and thinking how nice it would be for them to be able to listen to activities there, and today see that they have tracked Voyager 1 on March 31.

I suppose if you are going to command and listen to a satellite to go to Mars, AMSAT P5-A, the Moon would be a snap.

Have some links below about the AMSAT-DL / IUZ team.

Maybe when we go back to the Moon and there is more interest in the daily happenings, we will have an Amateur Radio team listening in and putting the daily news on the Internet for us all to view.

Thanks for looking up.

VOYAGER 1 received by AMSAT-DL group
Space probe VOYAGER 1 successfully received

On March 31st, 2006 an AMSAT-DL / IUZ team received the American space probe VOYAGER 1 with the 20m antenna in Bochum.

The distance was 14.7 billion km.
This is a new record for AMSAT-DL and IUZ Bochum.
The received signal was clearly identified through means of doppler shift and position in the sky. The receive frequency was exactly measured and compared with the information provided by NASA.

This distance equals approximately 98 times the distance between Earth and Sun. VOYAGER 1 is the most distant object ever built by mankind. This again proves the superior performance of the Bochum antenna. Most probably this is the first time Voyager 1 has been received by radio amateurs.

VOYAGER 1 was launched on 5. September 1977 by NASA. It transmitted the first close-up pictures of Jupiter and Saturn. In 2004 VOYAGER 1 passed the Termination Shock Region, where the solar wind mixes with interstellar gas.
VOYAGER 1 today is still active, measuring the interstellar magnetic field.

The following radio amateurs were involved:

Freddy de Guchteneire, ON6UG
James Miller, G3RUH
Hartmut Paesler, DL1YDD
Achim Vollhardt, DH2VA/HB9DUN

Special thanks to Thilo Elsner, DJ5YM of the IUZ Bochum, Roger Ludwig of Jet Propulsion Laboratory (JPL), Pasadena USA and the Deep Space Network Tracking Station in Madrid, Spain for their cooperation.

Raumsonde VOYAGER 1 von Funkamateuren empfangen

Am 31. März 2006 ist es dem AMSAT-DL/IUZ-Team erstmalig gelungen, die amerikanische Raumsonde VOYAGER 1 mit der Anlage in Bochum zu empfangen. Die überbrückte Entfernung betrug hierbei 14.7 Milliarden km und stellt einen neuen Rekord fuer AMSAT-DL und das IUZ Bochum auf. Das empfangene Signal wurde eindeutig durch die Dopplerverschiebung und durch die Position am Himmel identifiziert. Weiterhin wurde die Empfangsfrequenz mittels eines Rubidium-Frequenznormals vermessen und mit den Angaben der NASA verglichen.

Space probe VOYAGER 1 received from radio amateurs written of Hartmut Paesler Friday, 31 March 2006 on 31 March 2006 succeeded it to the AMSAT DL/IUZ team for the first time to receive the American space probe VOYAGER 1 with the plant in Bochum. The bridged distance amounted to here 14,7 billion km and sets up a new record for Amsat DL and the IUZ Bochum. The received signal was identified clearly by the Doppler shift and by the position in the sky. Further the empfangsfrequenz was measured by means of Rubidium-Frequenznormals and compared with the data of NASA.


P5A-Leitstation in Bochum
bestand Feuertaufe

An der Sternwarte Bochum (IUZ) steht der unter einem Radom geschützte 20-m-Parabolspiegel der für die P5A-Mission als zentrale Bodenstation dienen soll. AMSAT-DL hat die restaurierte Anlage mit der für Deep-Space-Missionen nötigen Steuerungs- und Hochfrequenztechnik ausgestattet. Die Bochumer Antenne war bei der Ankunft von Mars-Express und BEAGLE2-Lander zu Weihnachten 2003 live dabei. Sie konnte bereits über 1 Milliarde km entfernte Signale der Cassini-Saturnsonde empfangen.

P5A control station in Bochum existed fire baptism at the observatory Bochum
(IUZ) stands the 20-m-Parabolspiegel protected under a radome for the P5A mission as central ground station to serve is. Amsat DL equipped the restored plant with the control and high-frequency engineering necessary for Deep space missions. The Bochumer antenna participated 2003 live with the arrival from Mars express and BEAGLE2-Lander to Christmas. It could already receive over 1 billion km distant signals of the Cassini Saturnsonde.

The P5A mission.

Nach diesen Vorarbeiten hat der Vorstand der AMSAT-Deutschland das formelle GO im Jahr 2002 für die Mission zum Mars gegeben und erste Mittel für das Projekt freigegeben. Da diese das erste interplanetare AMSAT-Projekt ist, erhielt es in der so genannten Phase 5 die vorläufige Projektbezeichnung AMSAT-Phase 5A oder kurz P5A. In einem der Startfenster 2007 oder 2009 soll P5A seine mehrmonatige Reise antreten.

After this pre-working the executive committee gave to that AMSAT Germany the formal GO in the year 2002 for the mission to Mars and released first means for the project. Since this is the first interplanetary AMSAT project, it kept the provisional project designation AMSAT phase 5A or P5A short in the phase in such a way specified 5. In one of the starting windows 2007 or 2009 P5A is to begin its mehrmonatige journey.
