Abstract
A method and apparatus are provided for spoofing detection in the context of a vehicle-based GNSS receiver. An attitude estimate of the vehicle is obtained. A velocity estimate is calculated based on measurements provided by the GNSS receiver. The method comprises projecting the velocity estimate to a body frame of the vehicle, using the attitude estimate; deriving a detection parameter from the projected velocity estimate; and comparing the detection parameter with a detection threshold, in order to detect spoofing.
