Question

TESEO III accuracy

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

    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.
