teseo-liv4f + cep

[mich35]

Hello,

Is there any specific parameters to configure to acheive correct CEP?

Starting from default mode I found a CEP worst than some L1 only GNSS....despite I respect the 70x70mm ground plan for the antenna....

Many points are correct (but not more) but a few are awfull (more than 20m far away from position...)

Do you suggest any ceramic antenna?

Best regards

Hi

The module doesn't need any special configuration.

Do you have good CN0 satellite signals?

Which antenna are you using?

how are you testing? (open-sky... urban-canyon)?

Hi,

Actually I use antenna reference ANT-GNCP-TH258L15 from Linx but any other gestion is wellcome.

The prototype is outside on the dashboard of my car.

The teseo is power down, only VBAT is present. The teseo is power on and the 3rd correct position is recorded.

Best regards

>>Could be that the GBS was off by default in previous firmware.

Or just no implemented.

>>Could you confirm that an "empty" GBS message means ok?

Hard to tell you're not really providing enough context about what satellites the receiver is seeing, or the type of solution it is able to develop. Show a more complete set of NMEA sentences over a couple of seconds.

Hello,

The teseo GNSS is outside, on the roof of the car.

I linked the Teseo GNSS to your Teseo-Suite Pro tool.

I requested the configuration with your Teseo Suite and the result is :

$$PSTMSETPAR,1227,0xbc0003d5*06

But as shown, your teseo GNSS can only see GPS satellites:

How is it possible that only GPS satellites are seen?

Is there any other configuration to check?

Once again, previously to this firmware update, GGA messages were GNGGA and not GPGGA only..

I attached the log file with the GSV messages.

 

Best regards.

Hi

In the Teseo-Suite configuration, did you 'NMEA 4.x' as protocol parser?

Hi,

NO when I select NMEA 4.X the the signal level tool does not work!

Only the the view monitoring works correctly....

Do you have any other suggestion please?

Best regards

Hi

LIV4F as multi-bands device provides a NMEA-4.x ASCII stream.

Which Teseo-Suite version are you using?

 

In any case in the ASCII stream you can see if BeiDou/Galileo etc are acquired or not.
