radio amateurs received signal from VOYAGER 1

this is a translation, from a German Webside

On 31 March 2006 the AMSAT DL/IUZ team succeeded in for the first time receiving 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. This distance corresponds for instance to the 98-fachen distance earth sun or about the triple distance of the earth to the outermost planet Pluto. Voyager 1 is thereby furthest from the earth removed from humans built object. Hereby the efficiency of the Bochumer antenna was proven again. In all probability this is the first receipt of VOYAGER 1 of radio amateurs at all. VOYAGER 1 was started on 5 September 1977 by the American space agency NASA and conveyed the first close-ups of Jupiter and Saturn. In the year 2004 passed Voyager 1 sucked. Termination Shock region, in which the solar wind mixes itself with interstellar gas. Still today VOYAGER 1 data of the interstellar magnetic field measures. The radio amateurs taken part thereby were: Freddy de Guchteneire, ON6UG James Miller, G3RUH Hartmut Paesler, DL1YDD Achim Vollhardt, DH2VA/HB9DUN of special thanks applies for Thilo Elsner, DJ5YM of the IUZ Bochum, Roger Ludwig of the jet Propulsion Laboratory (JPL) in Pasadena/USA and the Deep space network Tracking station in Madrid/Spain.

this is fantastic i think:cool:

Thanks once again for finding a good foreign language story. This is really an excellent achievement. Just as with spotting new comets, there are still areas where amateurs can contribute to space sciences - but I imagine their equipment is quite expensive and not for the spare bedroom!

Thanks Ulli. thought Voyager was dead. Nice to think that ‘amatuers’ can contribute in today’s high technology science environment. :slight_smile:

Babelfish is my friend :smiley:

Excellent find Ulli! Amateur equipment is almost always a factor less expensive than the stuff used by NASA, universities, and such groups with much larger budgets. This sort of thing helps prove that you can do much with less, which in turn lets more people contribute to science.

Wow… not to mention just locating where to find the signal was a big accomplishment. At that distance its not an easy thing to do to pick up a signal as weak as Voyager is capable of sending. Its cool to just try and comprehend where the Voyager crafts have made it to.

I’m amazed they managed to find it. Excellent find Ulli :thumbsup:

for Info it is only a 20m radio telescope

fantasstic…

Second link is a very nice article about German space heritage being preserved and used Ulli. :thumbsup:
We forget what can be achieved with an old computer and BBC basic.
