The increase in the number of satellites for different constellations as well as the increasing use of multiple frequency GNSS receivers are fostering improvements in the achievable accuracy in GNSS positioning. However, they are also raising the requirements on the receiver antennas, due to the stronger impact that possible imperfections might have in the overall error budget for multifrequency combinations. The present work shows an analysis of antenna induced errors in pseudorange code measurements for different antenna feeding typologies, hence aiming at identifying advantages and disadvantages of such technologies for precise positioning.
