摘要： The present invention provides a system and method for determining the authenticity of reported positions of GNSS receivers, such as aircraft equipped with GPS positioning devices, and provides an in-band verification capability for GNSS positions by tasking one or more GNSS satellites as designated authentication support (DAS) satellites that transmit corrupted ephemeris data in a pseudo-random error corrupted C/A signal on the L1 band and GNSS receiver determine authentication ranges to the DAS satellites and transmit the DAS authentication ranges as part of their position report. The surveillance system can verify the authenticity by comparing the transmitted authentication ranges to true authentication ranges determined using actual ephemeris data and the known C/A code pseudo-random error for the DAS satellites.

摘要： The present invention improves the performance of existing secondary surveillance radar (SSR) transponder multilateration (MLAT) systems using a Time Lag of Arrival (TLOA) measurement. The present invention correlates TCAS interrogation messages and reply messages, which are transmitted on different frequencies, to determine TLOA measurements that are used with TDOA MLAT to achieve higher positioning accuracy and greater surveillance coverage than conventional MLAT systems. The present invention applies to any MLAT system including surface MLAT, Wide-area MLAT, active MLAT, passive MLAT, range-aided MLAT, non-range aided MLAT, Precision Runway Monitoring (PRM) MLAT, and any other MLAT system based on receiving SSR transponder signals. The present invention also applies to Mode-S transponder signals and ATCRBS transponder signals.

摘要： The present invention utilizes the existing DME transponder system infrastructure to augment existing ground surveillance multilateration (MLAT) capabilities by providing additional measurements for determining the position of an aircraft equipped with a DME transponder. DME listeners receive DME interrogation signals and DME reply signals, determine TDOA between the DME transponder and each DME listener, and transmit data to a central computer that clusters TDOAs between the DME transponder and the DME listeners and computes the aircraft position using the clustered TDOAs. The DME-aided MLAT can be used as a backup surveillance system when GNSS-based systems are unavailable. The DME-aided MLAT can be integrated with SSR receive units (RUs) performing multilateration (MLAT) calculations.
