Abstract

Method for verifying the integrity of measurements acquired by a plurality of GNSS receivers, associated computer program and verification system. The present invention relates to a method for verifying the integrity of measurements acquired by a plurality of GNSS receivers, comprising the following steps: - for each GNSS receiver: + determination (110) of a residual vector from the GNSS measurements acquired by this receiver in a corresponding time window; + determination (130) of an elementary covariance matrix of the residuals from said residual vector; - composition (140) of an overall covariance matrix; - determination (150) of a test variable from this covariance matrix; - comparison (160) of the test variable with a predetermined threshold. The size of each residual vector and each elementary covariance matrix is ​​adapted according to the number of satellites visible to the corresponding GNSS receiver.Figure for the abbreviation: Figure 2.
