Re: [time-nuts] GPS 50 bps recording today
Ok. I have a bin file recording going via winoncore12 of the Raw data from an M12 . I hope that it is OK.

I've two uBlox LEA-6Ts recording RXM-SFRB (0x02 0x11) subframe data with crummy indoor antenna positions (rain prevents me from getting 'em outside). I also have a uBlox NEO-7N recording the undocumented TRK-SFRBX (0x03 0x0f) subframe data, with a terrific outdoor antenna placement. Too bad the tbolt doesn't seem to send the subframe data--lots of those on the list. I'm sure the gfz-potsdam.de archive will have the data in a couple of weeks, but that's not quite the same as recording it yourself in realtime, is it? ;-) -- newell N5TNL ___ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
[time-nuts] GPS 50 bps recording today
Would someone be a hero and record the raw subframe data from GPS today? It's only 50 bits per second (that's about 8 bytes/second) per SV. A select few GPS receivers have binary commands that return this low level of detail: M12 (@@Tr), SiRF (8), uBlox (RXM-SFRB). My attempts to pull this off today have failed. It's your once* in a lifetime chance to record a GPS WNRO at the bit level. I'm looking for the raw serial data stream binary dump; something re-playable in the future, not some ascii output or screen shot. /tvb ___ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
