Hi,
I am still in trouble with getting GPS working properly.
My installed image is FSO-image milestone 4.1 and I have replaced gpsd
with fso-gpsd.
Running fso-gpsd and trying to telnet localhost gpsd mostly fails to
get a fix.
Yesterday I seem to get better results. Zhone showed up at least two
signals (not a fix) but today it failed.
But today there is really a nice weather.
Today I tried to install openmoko-agpsui to see the signal strength
and - see a fix in less than
two minutes (1.20 min) while holding the phone outside my window. That
compared to zhone, I will guess
fso-gpsd and the backend is very unstable in getting a fix compared to
what openmoko-agpsui shows me.
What makes there so much difference between openmoko-agpsui (running
gllin as seen in console)
and the zhone or fso-gpsd with telnet or even tangogps ?
I read something about dropped GPS data by kernel. How to see them to
get a feeling that this is the
cause (docu / link) ?
If that is not the problem, could I ignore fso-gpsd and set tangogps /
navit to use gllin as an interim solution ?
My signal strength inside the room 3 meters away from window is about
(avg/current) 19/20, 28/27, 23/20, 25/25, 24/25
while holding FR in my hand.
Sometimes a satellite gets lost but it comes back. Placing the phone
on desk decreases the signal down to ~19.
Then sometimes the satellites get lost. If I take it back in my hand,
agpsui get's back a fix.
This behaviour is well known to my conditions in my room. Are they ok
as described (hardware / antenna quality) ?
Any help is welcome. I will read the agpsui stuff to take a more
scientific measurement :-)
Where are the results of those measurements, if anyone has done that ?
While all that, my Sandisk 16GB microSD card is mounted, issuing many
ls command on it seems not to interfer
the signal. Also WLAN is on.
Thanks
