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

Mich

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.

Teseo Suite Pro 7.0.3.0 (downloaded last week)

I see GL, GA, GP and BD talkers for GSV messages

Hi

I'm using the same Teseo-Suite version (7.0.3.0)

LIV4F firmware version 4.6.3.5.3)

and teseo-suite parses the NMEA4.x from LIV4F without any issue.

BTW :

 > GL, GA, GP and BD talkers for GSV messages

The module is correctly acquiring the GPS, Galileo, BeiDou constellation.

So with the GNSS on the car roof on a parking and a test on 15mn I have a CEP of 2.3m.

Do you have advices to improve this?

As you can see sudenly latitude and longitude changed despite the GNSS did not moved...
