Patent abstract

An system and/or method for detecting outliers in satellite observations can include: receiving satellite observations associated with one or more satellite constellations; receiving sensor data; determining a GNSS positioning solution using a filter to process the satellite observations; determining a fused positioning solution; detecting whether outliers are present in the satellite observations; and when outliers are detected, updating the GNSS positioning solution and/or the fused positioning solution using a set of outlier mitigated satellite observations.
