NEO 6M question ?

[antonius]

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.​

[antonius]

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.

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.​

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
