Abstract
A signal processing method to avoid deception attack and apparatus for performing the same are provided. The signal processing method includes generating a synthesized signal by receiving a signal from a satellite, detecting a deception signal from the synthesized signal based on tracking information on a signal currently being tracked, separating a normal navigation signal from the synthesized signal in response to the detecting of the deception signal, and computing a normal navigation solution based on the normal navigation signal.
Claims18
A signal processing method to avoid a deception attack, the method comprising:
- generating a synthesized signal by receiving a signal from a satellite;
- detecting a deception signal from the synthesized signal based on tracking information on a signal currently being tracked;
- separating a normal navigation signal from the synthesized signal in response to the detecting of the deception signal;
- and
- computing a normal navigation solution based on the normal navigation signal,
- wherein the separating of the normal navigation signal comprises:
- determining whether the normal navigation signal is separated from the synthesized signal;
- and
- generating tracking information on the normal navigation signal when the normal navigation signal is determined to have been separated from the synthesized signal.
An apparatus for signal processing to avoid a deception attack, the apparatus comprising:
- a converter configured to generate a synthesized signal by receiving a signal from a satellite;
- and
- a signal processor configured to detect a deception signal from the synthesized signal based on tracking information on a signal currently being tracked, separate a normal navigation signal from the synthesized signal, and generate a normal navigation solution based on the normal navigation signal,
- wherein when separating the normal navigation signal, the signal processor is configured to:
- determine whether the normal navigation signal is separated from the synthesized signal;
- and
- generate tracking information on the normal navigation signal when the normal navigation signal is determined to have been separated from the synthesized signal.
