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.
