[amsat-bb] Re: e: Satellite technical question
Assume a cubesat with a monopole ¼ wave antenna at 400 mhz. The satellite is in full sun with a 500km orbit. What is the antenna temperature in full sun and in eclipse? It depends entirely on its color (surface properties). If it black it will get to about 55 farenheight in the sun and to about very cold in the dark. If it is white, it will get to about -60 F in the sun (Notice that is MINUS 60) and very cold in the dark. If it is clean shiny aluminum, it could get to +250 F in the sun and very cold in the dark all assuming they have no other way to conduct away heat. Those are steady state hot temps for the surfaces given. I dont remember the cold temps, though they will all reach the same very cold temps if they never see the sun. Notice that these are steady state. A metal sphere with these colors going in and out of eclipse will never reach these extremes because of their thermal mass that cannot get that hot in 60 minutes and cool down that much in 35 minutes of dark. Our basically black PCsat (solar panels mounted to the aluminum body with good conductivity only got to about room temperature in the sun and no colder than about freezing (32 F) in the dark every 90 minutes. But it was a shock to us when we designed a flip-out solar panel for a cubesat that is exposed on both sides to space. It gets to almost boiling on the sun side and down to about -70F in the dark... EVERY orbit. SO, I assumed that a thin tiny whip antenna could not conduct very much heat to the spacecraft, so its extremes will be high. But a piece of wire can easily handle these temps. But any solder joint that cannot communicate heat to/from the rest of the spacecraft might have problems. This is an off-the-cuff answer. Doing thermal in space is a real ART! Good luck.

[amsat-bb] Final Reminder - AMSAT-UK International Space Colloquium Guildford
A final reminder of this weekends Colloquium, look forward to seeing you there. 73 Trevor M5AKA The AMSAT-UK Colloquium takes place this weekend September 15-16 at the Holiday Inn, Guildford, GU2 7XZ, UK and is open to all. The Colloquium is a truly international event and will include: Exclusive access to inspect the new Surrey Satellite Technology Ltd (SSTL) clean room and integration facilities at the recently opened Kepler Building. If you have visited their previous facilities at the university campus, during previous Colloquia, you will be amazed by what is happening now. Presentations by experts from AMSAT-SA, AMSAT-NA and AMSAT-DL on their current spacecraft projects. CubeSat presentations on UKube-1, STRaND-1, STRaND-2a/b and, of course the FUNcube-1 project. We will be including an exclusive roundup of a number of new live and potential spacecraft projects that are under investigation and/or development. Additionally a number of presentations are planned covering new communications techniques and similar futuristic topics, along with the launch of the new FUNcube Dongle PRO-Plus Software Defined Radio (SDR) on the Saturday. Plus all the usual networking opportunities, the gala dinner and auction/raffle, plus the opportunity to operate the sophisticated ground station in the GB4FUN mobile demonstration module. The weekend event is open to all and attracts an audience that ranges from those involved in building and operating Amateur Radio satellites to beginners who wish to find out more about this fascinating branch of the hobby. All accommodation will be at the Holiday Inn hotel. Rooms and Saturday’s Gala Dinner must be booked in advance in the AMSAT-UK shop at http://tinyurl.com/2012-Colloquium-Shop Further information at http://www.uk.amsat.org/colloquium/twelve AMSAT-UK Colloquium – Visit to SSTL Kepler Building http://www.uk.amsat.org/?p=9565 Smartphone and Kinect Satellite Presentations at Guildford http://www.uk.amsat.org/?p=9946 Exclusive New SDR Product Launch at AMSAT-UK Colloquium http://www.uk.amsat.org/?p=9847 Dr. Mark Hammond N8MH to speak at Space Colloquium http://www.uk.amsat.org/?p=9388 IARU International Amateur Radio Satellite Forum at Guildford http://www.uk.amsat.org/?p=9862 ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Thanks for the NOVA and Camera advice!
Thank you to all who helped me with NOVA. I really feel dumb about my mistake of not looking up the REAL name of a satellite. I appreciate no one mentioning my ignorance. Thank you to all who commented on my camera on a beam. I forgot about the need for a telephoto lens. I also was not thinking about the advantage of the az-el rotator with respect to looking around the neighborhood(thanks Bob!). If I could get the correct keps, maybe I could even follow movement. Don't be surprised if I post some unusual photos instead of the green cheese on the moon. I have been a Ham for over 50 years and I am still trying to figure all of this stuff out. Working satellites has been my highlight of my 50+ years. This is one helluva great hobby! Thanks Everyone, 73 -james W5AOO ___ Sent via AMSAT-BB@amsat.org.
