Abstract
A receiver is configured to authenticate received satellite signals having a carrier wave carrying positioning data. The receiver includes a processor arrangement configured to analyze the carrier wave to determine an apparent acceleration between the satellite and receiver. The processor arrangement is also configured to compare the apparent acceleration between the satellite and receiver with a threshold value to determine if the satellite signal is authentic.
