[Gumstix-users] GPS readings are wrong.

[notstix <art...@ho...>]

hi.
Installed GPSstix and passive antenna. It works but readings are not
accurate.
I open http://maps.google.com/ and search my location with data got from
GPSstix and it's pointing not where I am. It's ~20KM off.

Here's output:
# cat /dev/ttyS2

(localtime is 19:40)

First line, 5923.62845,N,02430.98393,E and searching in
http://maps.google.com/ for 59.2362845, 024.3098393 I get wrong location. My
place is really 59.39N, 24.54E and not 59.24N, 24.31E.

Thats more than 20KM distance ! And it's always pointing me exactly there,
so I believe antenna is OK.

Do I have to take something in calculation?
