    ADSB Position error.

    Hello there,

    I would like to know wich are the requirements for any aircraft flying EASA (or whole ICAO if not possible) airspace for Position (Lat/Long) error.

    Normally this is provided by GPS receiver and has a position error (10 m for example in phone A-GPS).

    So, what error does ADSB work with? (1 meter, 1000 meters?)

    An FAA doc I read states that the maximum limit for ADS-B position accuracy is 0.05 nautical miles or approximately 304 feet or approximately 93 meters. All of the tested ADS-B systems in the report had an accuracy of less than 100 feet.
