Running back to the desire for DAO packets..... I am assuming that
with standard APRS packets having 2 decimal places and DAO having 3
decimal places that I will be locating a particular GPS receiver to an
area that is an order of magnitude more precise. I am probably not
saying this correctly, but with the standard APRS packet, I have an area
of uncertainty of about 20' x 40' ( in northern Wisconsin, US (
N45,W92)). By moving to a DAO packet, I will have an area of
uncertainty of about 2' x 4'.
If I have a bunch of GPS receivers of the same type, can I assume that
the relative location is pretty good, even if the absolute location may
be off a bit? I am really primarily interested in relative positioning.
Since Xastir is really just plotting the data it receives, I am going to
post this query on the APRS group as well, but I wanted to be sure to
catch Gerry <grin>...........
Many thanks, all................... jt
