GNSS measurements can be supplemented by the information available in EGNOS system
even if one has only GNSS receiver that is not processing Satellite-Based Augmentation
Systems data. The article describes how to obtain the variances of ranges to the satellites used
for positioning when the final antenna position and satellites’ elevation and azimuths values
are recorded. To verify how the resultant estimates of position error correspond to real errors
the research based on GPS receiver was conducted.
