An analogue RF receiver receives satellite signals and performs at least a frequency downconversion. Correlation and decoding functions are applied to the downconverted signals for deriving location information from detected specific satellite signals. The system further comprises a server for receiving samples of the downconverted signals, and for verifying the samples are consistent with the expected satellite signals at that time and location. The invention provides a counter measure for detecting the counterfeiting of, or tampering with, the satellite signals at the receiver. A check can be made that the received satellite signals correspond to those which are expected at that location and time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Processing of satellite navigation system signals and related receive-signal verification","description":"A system implements a location based service, and comprises a satellite navigation receiver implementing a position tracking function for providing the location of a user of the service.
