HamTV on the ISS update
Posted: Wed Nov 11, 2015 7:50 pm
Some of you may remember the presentation Graham, G3VZV, gave at CAT15 subtitled "Tim Peake on a TV near you" https://www.youtube.com/watch?v=W_1ITXF ... x7HXF9iEwP
Some of you may have also noticed a new station on the Tutioune map http://www.vivadatv.org/tutioune.php?wh ... 59c1cd46c2 located at Goonhilly in Cornwall.
This station is using a 3.8 mt dish is being loaned to the ARISS project by Satellite Catapult, (web link = https://sa.catapult.org.uk/) and will be used to track the ISS and provide real time video during the schools contacts scheduled for early next year. This dish is almost in the shadow of the 29 metre dish built in 1962 to receive the first transatlantic television signals from the Telstar-1 spacecraft.
Last week, we (G8GTZ, M0AEU and G3VZV) installed a PC with mini-tutioune software and a DB6NT downconverter to receive the ISS on the dish -
It was no surprise that during the tests, we received video for 8.5 minute during one pass and had an MER of 30 dB
Currently the dish is not tracking the ISS but will be doing so in the near future and will be dedicated to this task for the next 6 months In the mean time, the dish is pointing up at 90 degrees (zenith) but the receiver is connected and we received 25 seconds of blank video (visible on the TT monitor page) this morning when the ISS flew over the top of the dish!
There will be a full article on the ARISS Tim Peake project in the next CQ-TV along with pictures of the Goonhilly site.
Whilst we were at Goonhilly last week, Graham could not resist seeing if it was possible to receive the HamTV signal using only a handheld 60cms dish and the Tutioune software – much to the team’s surprise Graham was successful and this was the first reception of the ISS at Goonhilly as the equipment had was yet to be installed on the groundstation dish!
Lots more news on this interesting project over the next few weeks with the first contact due in the new year.
