History Of The Goonyhill Earth Station

Posted by on Friday, 29 October, 2010

 

Satellite earth stations have become a familiar fixture to certain landscapes. For example, the Goonyhill earth station became operational in 1962 on Lizard Peninsula in Cornwall. The first parabolic dish, named Arthur himself, was built on this site to communicate with the first Telstar satellite that was an international effort involving NASA, Bell Telephone Laboratories, AT&T, the French National PTT, and the British General Post Office.

 

Arthur was created by Bell labs for AT&T, and made it possible for America to transmit a live television signal to the BBC. The first earth station dish was approximately 25.9 meters in diameter and weighed over 1,118 tons. The success of the earth station Arthur and satellite communications lead to the construction of more earth station antenna to accompany Arthur. The accompanying antennae were named for characters from Arthurian legends.

 

The first satellite did not last as long as the first earth station. A nuclear weapon tested high in the atmosphere proir to Telstar launching and released radioactive particles in the Van Allen belts. The satellite was forced to travel through too much radioactivity, and was irreparably damaged.The first satellite ran into problems, but the first earth station only grew. With more than other 70 dishes,Goonhilly became the largest earth station. The amazing earth station helped operate mobile phones and shipping provided service to the North Atlantic and the Indian Ocean.

 

Goonhilly is not growing like it once was. Most of the earth station antennas at Goonhilly have been decommissioned, but Arthur is officially protected as a historically significant structure. It is possible that a few of Arthur’s fellow Arthurian antennae will also reach the same status. The site of the first earth station is next to Future World, which shows advanced communications technology available, both on earth as well as in space. Although the earth station is not the powerhouse it once was, BT is still committed to researching satellite technology and using the operational antenna. However, many of these may not remain in Goonyhill. Many of the operations that once occurred at the first earth station are now in Madely, Herefordshire.

Sound and vision: The spy monocular and long range sound detector

Posted by on Monday, 12 October, 2009

GGSPY007900_06_LI knew when I got to the Neighborhood watch meeting last week, that guy from down on the corner was talking about me again. I saw him outside, standing next to his car. Of course I take security a little more seriously then the rest of the people who just like to *say* that are protecting our neighborhood. Next time though, I’ll be able to hear him. I just bought the new Spy Monocular & Long Range Sound Recorder.

I know that jerk was talking about me. I know it. And if he thinks he’s going to get away with this, he’s in for a rude awakening. I know he’s been talking to the watch leader. Excessive use of force. Those damn kids in their hoodies deserved everything they got. Besides, I used a bag of oranges, not a pillowcase full of door knobs.. yet.

I’ll fix him next time. I’ll be watching and recording using the new 8x monocular with a parabolic dish from Brando. I even got a great deal on it, $44.00 plus shipping.
