FIELD: information technologies.
SUBSTANCE: geometric filter is applied to set of GNSS signal data with application of geometric combination of carrier phases to obtain array of ambiguity assessments for geometric combination of carrier phases and according statistical information. Bank of ionospheric filters is applied to set of GNSS signal data with application of ionospheric combination of carrier phases, which does not depend on geometry, for obtain array of ambiguity assessments for ionospheric combination of carrier phases and according statistical information. Bank of quintessence filters is applied to set of GNSS signal data with application of carrier phase combination that does not depend on geometry and does not depend on ionosphere to obtain array of ambiguity assessments for combination of carrier phases, which does not depend on geometry and does not depend on ionosphere, and according statistical information. Code filter is applied to set of GNSS signal data with application of carrier code combination aggregate, which does not depend on geometry and does not depend on ionosphere. Obtained arrays are combined to produce combined array of ambiguity assessments for all observations of phase.
EFFECT: increased speed and reliability of ambiguity resolution.
