1. A computer-implemented method of determining a posterior error probability distribution for a parameter measured by a Global Navigation Satellite System (GNSS) receiver, the method comprising:
receiving a value for each of one or more GNSS measurement quality indicators associated with the GNSS measurement of the parameter;
determining the posterior error probability distribution for the measured GNSS parameter by inputting each of the received measurement quality indicator values into a multivariate probability distribution model, wherein variates of the multivariate probability distribution model comprise an error for the measured GNSS parameter and the one or more measurement quality indicators, and the multivariate probability distribution model maps the error for the measured GNSS parameter to the one or more measurement quality indicators; and
acquiring, based on the posterior error probability distribution for the measured GNSS parameter, position information of the GNSS receiver to control navigation.
