When I observe NMEA sentences from a Ublox GPS in u-center, I see 7-digits of precision in both latitude and longitude. These numbers change by a small amount with each position report.
When I observe JSON emitted from gpsd, I see 8-digits of precision in both latitude and longitude. These numbers are static, and I haven't seen them change yet, though my receiver is stationary.
What I want, is for the position reports from gpsd, to reflect the exact positions as reported by the GPS. I figure then, that with 2 GPS units, I can cobble my own differentially corrected position reports.
I'm not understanding why the dgps output is static, and does not reflect the very dynamic GPS output?
Clues on what is going on here, anyone?
