Depends on multipath environment, number of satellites in view, satellite geometry and ionospheric activities So the sub-meter refers to DGPS. Regular GPS accuracy is around the normal.

Re: [Xastir] SX Blue II GPS
I looked at the brochure for this. There is something that tells me to beware of this. If it sounds to be too good to be true... I know that one time I did a one hour occupation of a HARN monument here in WI with my laptop and my Garmin GPS V. I then brought the data back and did some post-processing and I got within +/- 0.2 meters. I question the antenna. Looks like a fancy covered patch antenna. I really worry about the quality of the data. Besides, it is really that necessary for this kind of accuracy unless you are doing site surveys? 73 from 807, Richard, N6NKO Jason KG4WSV wrote: On Wed, Apr 30, 2008 at 7:27 AM, Lance Cotton [EMAIL PROTECTED] wrote: Nothing special here.
