data using the Pathfinder office interface.<span style='mso-spacerun:yes'>
</span>However, for the past several months it seems that CORS data is
unavailable the next day (or next several days) for most of the south east US
(we normally work in North Florida so would primarily use base stations in <st1:City
w:st="on">Gainesville</st1:City> / <st1:City w:st="on">Jacksonville</st1:City>,
<st1:place w:st="on"><st1:City w:st="on">Tallahassee</st1:City></st1:place>,
etc.<span style='mso-spacerun:yes'> </span>In order to correct our data we
have found the only base station that “works” is the DEP station in
<st1:place w:st="on"><st1:City w:st="on">Tallahassee</st1:City></st1:place>. Of
course this is fine for projects in the FL panhandle, but we are uncomfortable
using this station for projects much closer to the Jacksonville/Gainesville
area as they are 150km or more away.<span style='mso-spacerun:yes'> </span>I
have gone back to data we collected several weeks ago and tried to run it
through the differential correction process again.<span
style='mso-spacerun:yes'> </span>This time I will get some base data files to
download, but they are mostly incomplete (will only correct 50% or so of the
data).<o:p></o:p></span></font></p>
