Yuri's Night - THANK YOU
by Clint Bradford 13 Apr '11

13 Apr '11

Just finished breaking down the a/v equipment, my wife is loading the dishwasher, and we are pleasantly coming down off a great "high." Many friends celebrated this date with us in our back yard, along with our Icelandic horse and burro. (The burro's name is Edward R. Burro. If you are laughing, you are either a student of journalism, or more than 80 years of age ... (grin).) No, the ARISSat-1 was not heard on a great pass of the ISS at 9:56PM PDT. THANK YOU to the folks who called in via Skype! THAT was great for the party atmosphere! We got our live video feed shown to the planet, too! We showed the new First Orbit movie, along with other new and old videos. It's been a historic 48 hours. I hope we can get the scheduling together to perform whatever maintenance needs to be done to our ARISSat-1, and have it successfully deployed soon. Clint (now going to bed) Bradford, K6LCS

Hello, No word of ARISSat in the 4/12/2011 ISS status report, but they are watching an object that will make a close approach Friday. "Conjunction Advisory: Ballistics experts are tracking a conjunction with Object 33457 (Chinese CZ-4B Rocket Body) with a TCA (Time of Closest Approach) on 4/15 (Friday) at 6:31am EDT. This object is an intact rocket body with good tracking returns. It is classified as a medium concern at this time." http://www.nasa.gov/directorates/somd/reports/iss_reports/index.html 73, Armando N8IGJ

ISS Deception Reports
by Clint Bradford 12 Apr '11

12 Apr '11

>> ... I am curious why we need 100 reports that a signal was not heard? Because some of us are damned excited with this project ... It is also good to let others know that their setups are not necessarily improper - that those who "think" they know what they are doing are not hearing it right now. And besides - how many "50th anniversaries of man orbiting the Earth" can one celebrate in one's lifetime? Clint, K6LCS

Re: satellite average elevation
by Andrew Glasbrenner 12 Apr '11

12 Apr '11

Gentlemen, Your difference of opinion may stem from the fact that AO-6 through AO-8 had orbits that were in the 1450km range, and not the 600-800km that is more common now. That might hose up the numbers some, as the angles and path losses are considerably different. You just might be _BOTH_ right for the assumed scenario. 73, Drew KO4MA -----Original Message----- >From: Bob Bruninga <bruninga(a)usna.edu> >Sent: Apr 12, 2011 2:24 PM >To: amsat-bb(a)amsat.org >Subject: [amsat-bb] Re: satellite average elevation > >> As I said, in the "goode olde dayes" we used >> 30 degree up tilt and it worked well... >> Lessening the up tilt may increase the gain >> for the lower angle passes but will also decrease >> the gain on the higher angle passes.
