Has anyone had any luck getting Pharos GPS-360 to work?


I have a Pharos GPS-360 which I have plugged in and the system has recognized:

Code:
[nathan@ebisu ~] lsusb
...
Bus 001 Device 002: ID 067b:aaa0 Prolific Technology, Inc. Prolific Pharos
I can see that the right driver is being loaded:

Code:
[nathan@ebisu ~] dmesg
usb 1-2: pl2303 converter now attached to ttyUSB0
I can run gpsd:

Code:
[nathan@ebisu ~] sudo gpsd -N -n -D 2 /dev/ttyUSB0
gpsd: launching (Version 2.37)
gpsd: listening on port gpsd
gpsd: successfully connected to the DBUS system bus
gpsd: running with effective group ID 0
gpsd: running with effective user ID 0
gpsd: opening GPS data source at '/dev/ttyUSB0'
gpsd: speed 9600, 8N1
gpsd: garmin_gps not active.
gpsd: gpsd_activate(1): opened GPS (5)
gpsd: speed 4800, 8N1
gpsd: ntpd_link_activate: 0
gpsd: FV  0x06: Firmware version: PharNav: 07S203
gpsd: FV  0x06: Firmware version: 231.000.000ES
gpsd: Firmware has XTrac capability
But then it doesn't seem to work. gpsprof just sits there "looking for fix" and gpsdrive has no idea where I am.

Any ideas?
Nathan

Possibly dumb question, but you are outdoors when you try this, right? Or at least have the GPS receiver out a window? They won't work indoors, 99% of the time...

Good question...I put it on the windowsill, but didn't actually put it outside. I don't have a Linux laptop with me right now, but once I get to it on Monday then I'll try standing outside and see if it works better.

Thanks for the suggestion.

No problem...GPS signals are weak, and will drop out easily. Most service-bays (like for cars/trucks, etc.), that work on such things, will have a GPS re-radiator mounted on the roof. Gives a 30 meter bubble within the service bay, that will be just like being outside. We have one in our computer room, so our GPS units can hook up well. Lets us use cheap GPS receivers for very accurate NTP servers, using the PPS kernel under Linux.

I have a Garmin 18 and a Garmin Nuvi and can usually get a decent lock with the antenna placed in a windowsill but it needs to have an unobstructed view of the sky. As TB0ne posted the signals are weak.

Not sure what type of status is available with gpsdrive but I use the xgps and cgps utilities to see if it has a good lock. It will tell you which satellites its seeing, lat/long etc. I do not see anything obviously wrong with your gpsd status messages.
