ARISSat-1 1219 UTC

Great pass over Chicago. Strong signals, copied voice telemetry, greetings, SSTV. Following the threads here, it may not be perfect but it's a hell of a lot better than Suit Sat and is proving new systems and technologies. As far as "educational outreach" goes I know that the ham community is a friendly and welcoming place, that's why we reach out. I also know that some members of the satellite ham community are very upset that the dream of HEO and geosync are not reality. You can blame and point the finger at whoever you want, it's a simple fact that it costs money to get there, even as a ride share you are talking about a minimum of $1M so unless you are ready to pony up the bucks to get there.......

ARISSat-1 Pass 1229z 8/4/2011

What a signal! I have to admit, I didn't think it would be as good as it was. When ARISSat-1 was at 35 degrees, the signal was full-quieting. Decent SSTV pix received as well. Totally awesome!

ARISSat Heard In DO33
by B J 04 Aug '11

04 Aug '11

I heard the CW beacon at 1217 UTC with a strong (min. S5) but noisy signal. The FM downlink wasn't as strong as the beacon and was much noisier (possibly from local interference), fading about once per second. However, I did hear a child's voice giving part of the satellite's ID, but that was about it. 73s Bernhard VA6BMJ @ DO33FL

ARISSat-1 Update
by Gould Smith 04 Aug '11

04 Aug '11

ARISSat-1/Kedr continues to work well with good reports coming in from around the world. Good SSTV images submitted to the SSTV database, even earth and cosmonaut images, check out http://www.amsat.org/amsat/ariss/SSTV/ The transponder is working! Drew, KO4MA was successful in easily working through the transponder with a 1 W uplink BPSK-1000 Telemetry & Experiment data is coming into the telemetry server, check out the mobile app www.arissattlm.org/mobile The satellite is warmer than we expected, we will continue to monitor this. Very good first day. 73, Gould, WA4SXM and the ARISSat-1 team

Hi all, Apologies - I may have caused the confusion in my recent report on hearing the satellite this morning in Wales -UK. I had the ISS on my mind with using it with using it as a source for tracking ARISSat-1 and posted an incorrect frequency. It was of course operating on the correct published frequency. Put it down to "age" or my pleasure of having such success. Sincere Apologies to all. Ken Eaton GW1FKY

ARISSat-1 in Intermittent Mode Over USA
by Richard Crow 04 Aug '11

04 Aug '11

Since ARISSat-1's first three passes over the USA have occurred in darkness, it appears it is in intermittent mode. This is as Gould Smith stated in his post titled "ARISSat-1 Deployed !". That is, "ARISSat-1 will ... go to Low power (intermittent) mode when in eclipse". On the 145.950 MHz FM downlink, intermittent mode appears to mean about 45 seconds ON followed by 120 seconds OFF. Presumably, other signals from ARISSat-1 follow a similar schedule. I'll check this when I get a chance. That being said, ARISSAt-1 was heard loud and clear on all of its first three passes over northeastern USA near Binghamton, NY. Specifically, the 04:20, 05:54, and 07:31 UTC passes. Can't wait until the 09:08, 10:45, and 12:21 UTC passes for my location when ARISSat-1 will enter full sunlight and switch to continuous operation. Richard N2SPI

by David Barber 04 Aug '11

04 Aug '11

UK Pass 07.45utc. Last pass of the day at only just 10dg elevation and I managed to capture 2 telemetry frames and 2 Kursk frames amongst all the local crud and noise. Good to get the whole set first time round, great fun. Thanks guys. David G8OQW ********
