Abstract:
Wave based signals such as radio transmissions are susceptible to frequency alterations caused by the relative movement between a transmitter and a receiver. In a satellite context, the radio signals emitted by a satellite based transmitter may take on a frequency higher or lower than the actual frequency at which they are generated depending on whether the satellite is moving toward or away from the receiver, respectively. By calculating the theoretical frequency shift (Doppler shift) that should occur if a signal travels directly from a satellite to a receiver, the actual frequency of the signal as received can be used to determine if the signal's integrity is sufficient or if it has been compromised by some sort of interference or malfunction.

Claim (Index 10):
A method of integrity analysis of a plurality of radio signals, comprising:\n calculating a plurality of expected Doppler values regarding a frequency at which each of the plurality of radio signal is anticipated to be received at a receiver based on an assumed location of the receiver and an assumed location of each of a plurality of transmitters, wherein each of the plurality of expected Doppler values corresponds to one of a plurality of radio signals each sent from a corresponding one of the plurality of transmitters; receiving the plurality of radio signals at the receiver; determining a plurality of actual Doppler values corresponding to each of the plurality of radio signals; calculating a plurality of individual Doppler error values for each of the plurality of radio signals based on respective expected Doppler values and actual Doppler values; and using the individual Doppler error values to determine an integrity for each of the plurality of radio signals.
