You get the solar stuff as wideband noise ( look a bit around http://www.aip.de/groups/osra/ ) with some interesting profiles over time and frequency Now if wideband QRN(or QRM) goes drastically up signal to noise goes down for the GPS signal. ( The regular signal level is well below noise levels anyway ) uwe I could request some data i have access to for that day. unfortunately that instrument was only partialy working in that period. _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
