Anyone have a calculation/estimate of cell phone functionality in space? Would it be able to transmit and receive a signal from/to earth? Dave

ISS Re-Boost Cancelled
by Armando Mercado 03 Feb '09

03 Feb '09

Hi, The re-boost scheduled for tomorrow has been cancelled. Apparently the last re-boost in January caused excessive shaking to the station and flight controllers want to understand why before they do another burn. See: http://www.msnbc.msn.com/id/28998876/ 73, Armando, N8IGJ

Cubesat CX??
by jlv 03 Feb '09

03 Feb '09

Hello to all, We are an university of Uruguay without many economic resources, but we have a great potential human and big desires that to build a cubesat with our students of the career of electric engineering. We are following the steps toward the learning on this topic but we need some help. Until here we have arrived in a year of work: http://iie.fing.edu.uy/twiki/bin/view.cgi/Satelite/GloboSat01Informe http://iie.fing.edu.uy/twiki/bin/view.cgi/Satelite/GloboSat02Informe http://iie.fing.edu.uy/twiki/bin/view.cgi/Satelite/GloboSat03Instructivo http://iie.fing.edu.uy/twiki/bin/view.cgi/Satelite/GloboSatsMain We have tried to achieve the help of some people had involved for many years in projects with satellites but them they don't have the time to look toward an university with low resources that she cannot pay for their services. Do you know some person that has the time and the enough generosity to help us in our project? Thanks to all in advance for the help that you can give.

Iranian satellite technical round-up
by andy thomas 03 Feb '09

03 Feb '09

Satellite called OMID ("hope" in Farsi) is described by Teheran as a "data processing satellite". associated press quote: "Iranian television said the satellite would orbit at an altitude of between about 155 and 250 miles. It was taken into orbit by a Safir-2, or ambassador-2, rocket, which was first tested in August and has a range of 155 miles. The radio report said the satellite is designed to circle the earth 15 times during a 24-hour period and send reports to the space center in Iran. It has two frequency bands and eight antennas for transmitting data." AP also quote: "Ahmadinejad said Tuesday that the satellite, which he said had telecommunications capabilities, had reached its orbit and had made contact with ground stations, though not all of its functions were active yet. The launch was intended to be a message of peace and friendship to the world..." which makes me wonder if there's a beacon on it. There's another report talking about an interest in store-and-forward capability but not clear if this has it or not. Would have thought the satellite will decay earlier rather than later? http://www.google.com/hostednews/ap/article/ALeqM5h4ynWXGgXIWuMo6jcZGbdrhyu… 73 de andy g0sfj

Re 70cms satellite polarity?
by Angus 03 Feb '09

03 Feb '09

Thanks to all for information, until I can get hold of some more quality coaxial relays to build a 4 way polarity control box, I shall build the simple RHCP/LHCP switching unit as shown in the ARRL Handbook, this will allow me to switch between the two modes as needed, although I would like to try and build a complete unit allowing four modes of polarity control, when some quality coaxial relays are found. regards Gus -- I am using the free version of SPAMfighter.
