Help with AO27
by Ed Tump 10 Nov '07

10 Nov '07

Folks, If I read this right, the satellite will not be "on" during the pass over my home: AO27 schedule UTC Sat Nov 10 19:19:57 2007 Digital Med Sat Nov 10 19:20:17 2007 Analogue Med Sat Nov 10 19:27:17 2007 Digital Med Sat Nov 10 19:28:17 2007 OFF Sat Nov 10 21:00:46 2007 Digital Med Sat Nov 10 21:01:06 2007 Analogue Med Sat Nov 10 21:08:06 2007 Digital Med Sat Nov 10 21:09:06 2007 OFF The pass over my house is listed on Orbitron as happening at 20:59 UTC. Does my figuring make sense? Thanks, Ed KC9GWK New AmSat member

Re: AO-16 partially recovered.
by W.J. Ubbels 10 Nov '07

Hi Drew, good to hear that AO-16 is partially alive again, it serves as an excellent off-air test signal for testing the telemetry decoding software for Delfi-C3, which will also transmit 1200bps AX.25 BPSK. At http://esther.esrac.ele.tue.nl/ao16/ you can find 24/7 automatically tracked passes of AO-16 (including .kss files) by the backup groundstation for the Delfi-C3 mission at Eindhoven University (PI4TUE) in JO21RK. 73 Wouter Jan PE4WJ -- Wouter Jan Ubbels MSc Delfi-C3 project manager electronics & communications www.delfic3.nl Faculty of Aerospace Engineering Delft University of Technology The Netherlands PE4WJ

AMSAT Mobile Satellites Galore
by Robert Bruninga 10 Nov '07

10 Nov '07

November should be a great Mobile Satellite Month. There are 7 satellites you can work from your mobile FM rig, including PCSAT-1 which should fully recover by this weekend and last for 2 or more weeks. So now is the time to get going with live satellite contacts via these easy FM satellites, or setting up a SATGATE (Igate). DOWNLINK SATELLITE -------- ------------------------------------- 145.825 ISS APRS digipeater 145.825 PCSAT-1 (recovery expected 3 Nov) 145.825 ANDE-1 (re-entry expected next month) 435.225 GO-32 +/- 10 KHz and 9600 baud 435.300 AO-51 *FM Voice* +/- 10 KHz 436.795 SO-50 *FM Voice* +/- 10 KHz 436.795 AO-27 *FM Voice* +/- 10 KHz As you can see, there will be over 40 passes per day with 18 for the 1200 baud satellites, 6 per day for the 9600 baud GO32 and 18 for the voice birds. All 1200 baud pass times are between about 6 AM to 1800 local sun time in the Northern Hemisphere. GO-32 and AO-51 voice birds are in the morning and evening, AO-27 is in the afternoon. It is trivial to know when to operate these birds WITHOUT A PC. Please see the manual-tracking page: http://www.ew.usna.edu/~bruninga/MobileLEOtracking.html The packet path on 145.825 is VIA ARISS for all three satellites. The path for GO-32 is VIA 4XTECH and uses two different uplinks: 145.85 for APRS software and messages. 145.93 for all Mic-E, D7 and D700 radios. That's more than one pass per hour on 145.825. Lots of contact potential from your mobile... For APRS birds: http://www.ew.usna.edu/~bruninga/pcsat.html http://www.ew.usna.edu/~bruninga/iss-faq.html http://www.ew.usna.edu/~bruninga/ande-ops.html http://www.ew.usna.edu/~bruninga/GO32-ops.html For AMSAT birds: http://www.amsat.org/amsat-new/satellites/status.php For many of these satellites, you don't even need a tracking program. Just a slip of paper on the dashboard... See: http://www.ew.usna.edu/~bruninga/MobileLEOtracking.html The best antenna is a 19.5" whip in the center of your roof. 5 dBi gain on the 2m uplink and almost 8 dBi gain for the very weak UHF downlink (above 25 degrees)... Watch for special event info. WB4APR, Bob

Re: Simulated Emergency Test via Satellite
by Bob Bruninga 09 Nov '07

09 Nov '07

Simulated Satellite Emergency Test: I now see 74 PCSAT-1 users in the last 24 hours on http://pcsat.aprs.org I cannot count up the SSET emails till I get to work on Monday, but of those 74 users, 50 of them have sent about 822 messages via PCSAT-1 or ANDE or GO32 or maybe even ARISS over the weekend (2-4 Nov). By the way, this is NOT just APRS hardware and software. Anyone with a TNC and a radio can send their SSET checkin email. Just set your TNC BTEXT as follows: BT :EMAIL....:YOUR_EMAIL@WHATEVER.COM checking in for SSET!... Oh, replace the 4 dots after the word EMAIL with four spaces. The above format is an APRS message that will get ingested into the global APRS system and will get emailed to your_EMAIL (or any other email address you specify). Also set UNPROTO APRS VIA ARISS Set beacon to once every minute if attended until you see success. If unattended, set to once every 5 minutes. If successful, you will receive that message via your EMAIL. This demonstrates your ability to enter a EMAIL and or position and or status from anywhere on the planet in case of emergency TO any email address.. Join the SSET (Satellite Simulated Emergency Test)!

GO-32 and Doppler.
by John Ronan 09 Nov '07

09 Nov '07

Hi, I was wondering if there is a convention or best practice for doppler tuning on Digital Sats. I.e is it small steps and often or large steps and less often? I'm using an FT-847 and monitoring GO-32. I seem to be able to go as low as 10hz resolution. Just wondering. Regards de John EI7IG
