Extraordinary, indeed! Can someone tell me what all five objects are at, say, the 6:15 minute mark on the video? Clint Bradford

CP6 satellite, data decoding using CPX data decoder
by Dr. Jay Garlitz 31 Jul '09

31 Jul '09

Check out http://moredbs.atl.calpoly.edu/satellites/CP6/passes/2875. Six packets downloaded on one pass with new settings in IC-910. This was an attended pass with fine tuning the signal manually using the CW beacon as a guide. The best automated pass so far was three packets decoded. TLE in online primer located at http://www.gatorradio.org/CP6_tutorial.pdf gave reception from horizon to horizon and packet decoding (adequate signal strength) above 9 degrees. My home ground station is based on the same equipment as W4DFU at the University of Florida Club station. Students will join me there tomorrow to do the same, then set-up for the newly launched cubesats. UF swampsat is under construction. See www.gatorradio.org <http://www.gatorradio.org/> for club info.

Re: Pollux in APRS Database
by David Johnson 31 Jul '09

31 Jul '09

Hi Mike, In principle yes, you might have some packets that other people have missed. The problem is that the packets are time-stamped when they go into the database within a few seconds of actual receipt. (propagation time across the internet). So in reality, if there is a delay of more than a couple of minutes it could cause problems. Better to decode and publish here for the moment, I think. 73 - Dave Mike Rupprecht wrote: > Hi Dave, > does it make sense to play back my audio file and igate the CASTOR/POLLUX > packets into the APRS network ? > > 73, Mike > DK3WN > > -----Ursprüngliche Nachricht----- > Von: amsat-bb-bounces(a)amsat.org [mailto:[email protected]] Im > Auftrag von David Johnson > Gesendet: Freitag, 31.
