Definitions

  • the measured pseudo-ranges can be processed to determine the position of the navigation receiver.
  • the three-dimensional coordinates of the navigation receiver can be determined; a reference Cartesian coordinate (X,y,Z
  • the geosynchronous relay satellite 160 then retransmits the consolidated set of error correction data over a specific region (zone) of the Earth. Multiple geosynchronous relay satellites provide coverage for multiple zones.
  • the rover 170 receives the consolidated set of error correction data from the geosynchronous relay satellite 160 via the satellite signal 161. The rover 170 then calculates its position from the navigation signals and the consolidated set of error correction data. Note that the navigation receiver 172 in the rover 170 needs to be specially equipped to process the satellite signal 161.

  • the navigation data includes GNSS information (such as satellite ephemeris and satellite clock parameters) encoded on the navigation signals.
  • the navigation data also includes code phase measurements (that is, delay times used to determine pseudo-ranges) calculated from delay-locked loops (DLLs). If the navigation receiver processes carrier phases, the navigation data also includes carrier phase measurements calculated from phase-locked loops (PLLs).
  • the output digital signal 419 is input into the control and computing system 416, which computes target parameters such as position, velocity, time offset, and attitude.

Abstract

L'invention concerne un appareil permettant de détecter une usurpation de géolocalisation et navigation par un système de satellites (GNSS), comprenant un récepteur GNSS qui comprend une première application frontale radiofréquence (RF1) connectée à l'antenne (1) ; une seconde application frontale radiofréquence (RF2) connectée à l'antenne (2) ; une section numérique connectée à la fois à RF1 et RF2 et commandée par un oscillateur à fréquence unique. La section numérique génère un premier ensemble de mesures brutes GNSS sur la base de signaux reçus en provenance de l'antenne (1) ; génère un second ensemble de mesures brutes GNSS sur la base de signaux reçus en provenance de l'antenne (2) ; calcule des différences individuelles entre des mesures brutes simultanées, générées avec les signaux reçus en provenance de l'antenne (1) et de l'antenne (2) pour le même satellite GNSS ; compare les différences individuelles avec un seuil ; et émet une alerte d'usurpation lorsque plus d'une des différences individuelles sont inférieures à un seuil.
