I've been reading that, but have not had any success in getting any UBX output... I have managed to disable NMEA (both using $PUBX NMEA extensions and your UBX generator) but then I get no data on the tty. > | Additional test results (from 20080802) are up at > | http://www.millions.ca/~stacy/neoFreeRunner/gpstale.html > Doesn't look a million miles away from being right... there are two > outliers shown and I guess the filtered NaN(s), but basically all the > other samples are in a decent place. Atleast one of the outliers had multiple samples, but I am suspicious of those being synthetic as well. From the bit of testing I have done so far, it would seem that heavy use of the SDCard can cause the CEP to increase by 25%-50% but it is still typically better than the reference receivers. I had hoped to do my next round of testing in UBX mode (if that solves the issue with samples coming faster than once a second). If I can't get that figured out soon, I will just configure the GPS to only emit GGA sentences, then I will only get one fix per second from gpsd. -stacy _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
