Re: [gpsd-users] GPS fix issues

[Chris Kuethe]

Totally a wild guess: your receiver is returning a position estimate with very high DOP or a fix with the Alarm or Void flags set until it firms up its solution.

To see exactly what's going on, try running gpsd in foreground debug mode (eg. gpsd -nND3 /det/ttyS1 2>&1 | tee gpsd.log) to capture gpsd's internal state, and use gpspipe to see what's being passed through. You'll want to use both "gpspipe -Ro gpspipe.raw.log" and "gpspipe -wo gpspipe.gpsd.log".  Comparing these logs might give you some insight as to the cause of the delay.

Hi all,

I'm using gpsd on my embedded system based on an arietta G25 module running on Linux buildroot. I'm using gpsd to get positioning information, with a gps GlobalTop Ladybid 3 connected to a RS232 serial port.

The GPS communicate good and i can see NMEA frame, when it fix, it works perfectly but I have some fix issues when i'm running the gpsd deamon: without gpsd, fix time : arround 45sec and with gpsd arround 2min. I do all my tests in the same conditions, the only difference is gpsd

Do you know where this problem could come from ? Feel free to ask if you need more informations

Regards,

Florian

GDB has a 'break' feature; why doesn't it have 'fix' too?
