Hi,

Doing randoms tests on the TESEO III accuracy, I've found an horizontal accuracy of 14m for 95% of the locations with extremes of 23m. Does ST have more informations about the TESEO III accuracy ? Are there tests that have been published ?

Thanks

Regards

    I'm sure they have published CEP specs.

    Your results do seem particularly awful, but I think that's on you and your antenna or RF side. Does not seem consistent with a properly executed test. When peopl​e generate spec numbers it is usually with very expensive and very well placed antennas to provide optimal results.

    I've posted plots to this GNSS subforum.​

    CEP99 well inside 5m, and the bulk of the hits well inside 2.5m

    Make sure you don't have airflow over the IC or TCXO

    Are you using SBAS ?

    Ciao

    Teseo3 in the default configuration guarantees:

    • 1.5m CEP50 (this is public result in the DS)

    and we are close to

    • 2m CEP90

    I think there something strange in your platform.

    SBAS is On by default in ST firmware.
