Abstract
A method for detecting spoofing comprises monitoring signals from GNSS and SBAS satellites with a GNSS receiver; obtaining current time and orbital parameters from the receiver, based on real-time signals from the satellites; computing orbital positions based on the current time and orbital parameters; retrieving past orbital parameters; calculating predicted orbital positions based on the orbital parameters with respect to current time and the past orbital parameters; computing current orbital positions based on current satellite signals; determining a first distance value between two or more of the satellites based on the predicted orbital positions; determining a second distance value between two or more of the satellites based on the current orbital positions; comparing the first and second distance values to obtain a discriminator value; determining whether the discriminator value is greater than a threshold level, and outputting a spoofing alert when the discriminator value is greater than the threshold level.
