?MASat-1 heard
by Bruce Robertson 14 Feb '12

14 Feb '12

Scanning for the new cubesats on a 5 deg. pass, I heard early in the pass a signal on 437.351 at 13:37UTC today. Since it sounded like GFSK and the frequency was right, I assume this was MASat-1. I also heard a CW signal on the 70cm band, but it didn't seem to be A1A, and none of the current crop seem to use a different CW keying scheme on 70cm. then I found a CW signal and manually tuned it for most of the rest of the pass, until I realized it was XI-V! Argh! 73, Bruce -- http://ve9qrp.blogspot.com

Hi OMs, MaSat-1 seems to me as great CubeSat. The signal during revn 5 was very strong at max elevation 12 degrees at me in Brno. Number of detected Packets was 74. The audio file: http://www.urel.feec.vutbr.cz/esl/files/Othact/masat1_rev5.wav Congrats Budapest Team! 73, Mirek OK2AQ

ARISSat-1 Keplerian Element Analysis
by Joseph Armbruster 14 Feb '12

14 Feb '12

Everyone, I started digging into the ARISSat-1 Keplerian Elements in more details. See some of my effort here: http://libjoe.blogspot.com/2012/02/arissat-1-keplerian-element-analysis.html Right now I am generating some basic plots but I wish to do much more with this, such as: - intersect this with the telemetry data - there are many ways to do this the first will be plotting temperature values along the line of orbit as the satellite entered / exited eclipse - maybe generate a few fly-by videos that show line-of-site to a particular station that was receiving telemetry / sstv at that particular time If you have any comments or suggestions, feel free to share them. I am really excited right now because I am using my code and made my first correct plots this evening! If we knew (or could predict) the satellites orientation at a particular moment, I could drop in a model of ARISSat-1 into the scene and orient it correctly. I think this will be a great way to interactively visualize what happened during the satellites lifetime. Joseph Armbruster, KJ4JIO

ESA Launched cubesats
by Etienne Swart (WACO) 14 Feb '12

14 Feb '12

I have noted that the cubes have a LO elliptical orbit. When reporting a signal, would it not be advisable to report altitude of the cube? I have very high passed over Johannesburg. 1300-1430 km's Can't wait to work the generic of AO16. 73's Etienne Note: This message is for the named person's use only.

K7UGA report - Monday evening
by Patrick STODDARD (WD9EWK/VA7EWK) 14 Feb '12

14 Feb '12

Hi! It's Monday evening, or Tuesday (14th) on the UTC clock. I was on the 0218-0230 UTC VO-52 pass as K7UGA, and plan to work one more pass this evening - an SO-50 pass at 0351-0405 UTC. Thanks for the QSOs so far! On Tuesday in the early afternoon, I hope to work the SO-50 pass at 1943-1958 UTC. I can't stretch my lunch time to cover the AO-27 pass that starts about 2019 UTC, and SO-50 gives me more time to (hopefully) work stations than I can in the 7 minutes on AO-27. For Tuesday evening (early Wednesday on the UTC clock), I am looking to work the following passes: VO-52 at 0235-0247 UTC (satellite passing directly over my head) VO-52 at 0413-0422 UTC (low pass over the west coast) SO-50 at 0420-0433 UTC (starting to my north, going around to southeast) I may stop working the VO-52 pass around the time SO-50 comes up from the horizon, as I don't have great visibility to the northwest from my house. For Wednesday, I'm hoping to work one midday pass: SO-50 at 1832-1845 UTC (starting to my south, going around to northeast) I am not sure about my Wednesday evening (early Thursday, UTC) plans yet. I plan on working passes on Thursday morning and around midday from the back yard (VO-52, SO-50, possibly AO-27) before driving to Yuma and on to California. I may skip working passes Wednesday evening, and focus on the daytime operating Thursday morning instead. I'll post more about that tomorrow night or Wednesday morning. 73!
