Abstract
A method is provided for calibrating a vehicle-mounted GNSS antenna. The method comprises measuring a response of the antenna, while the antenna is mounted on the vehicle. Based on the measured response, data characterizing a group delay variation of the antenna is calculated. The data may be used to correct ranging measurements derived from GNSS signals received via the vehicle-mounted antenna. Alternatively or in addition, the data may be used in estimating the integrity of a position fix.
