Hybrid GNSS Antenna Characterization for Automotive Scenarios

The accuracy of GNSS signal reception is crucial for precise navigation and geodetic positioning. Environmental interactions can cause signal distortions and multipath effects, impacting GNSS antenna group delays (GDVs) also known as code phase variations (CPVs). This paper addresses the accurate prediction of installed antenna performance in automotive scenarios. It introduces a hybrid calibration approach combining real-world data and simulations to enhance GNSS antenna performance predictions. This allows the simulation to reconstruct the effect of the mounting platform on the data of the individual antenna already measured in an anechoic chamber and thus predict the final error of the installed antenna on the platform.
