Then I don't know - deleting the pickle file was the fix for me.
You may want to take a look at the mailing list archives, there are
various procedures for checking that the gps has power and such.
For example:
telnet localhost gpsd
r
You should get at least one message per second after hitting "enter"
after the "r" - whether you have a fix or not. If this works, then
things are mostly ok you just don't have a fix. If you get nothing, then
there are communication or power problems that prevents the gps unit
from working.
You may also want to try
grep ogpsd < /var/log/frameworkd.log
check if there are any messages indicating trouble. this particular one
is normal, although it looks like a problem:
2009.02.25 22:47:06 ogpsd WARNING (could not write to
'/sys/bus/platform/devices/neo1973-pm-gps.0/power_on': [Errno 2] No such
file or directory:'/sys/bus/platform/devices/neo1973-pm-gps.0/power_on')
