Dear Member,
I tested my GPS module with moving car,
I can not see any result, but when the car stopped, I saw the result,
I can not see the speed as well on GPS.GPVTG.kph, any same experiences ?
Any ideas on how to fix it ?
Thanks

Should work reliably at quite high speeds.
Use a magnetic mount antenna on the roof, check signal strengths and issues with electrical continuity and vibration. Air flow over module might also be problematic.

how can I mount that antenna ? replace my current antenna with roof antenna ?
I closed the car's window, how can I check signal streght, is it available on NMEA message ?
I put the module on the cartoon box and sit on my lap.

I can see UTC time from the module continuously displayed, but lattitude, longitude and altitude were gone, speed and cogt were not available as well always 0.000

Depends on the make/model board you have the GPS module on. For this type of application you'd really want a board with an SMA connector so you can use a cabled antenna.
The $GPGSV sentences should provide satellite related data.

It's GY-NEOMV2 module, yes it has SMA connector, but I don't have a long wire antenna, only a short wire antenna comes with the module,
I need the external long wire to get better signal ?
Thanks

Can I use this antenna with the module ?
thanks
