  • Patent number: 10094930
    Abstract: A system to detect spoofing attacks is provided. The system includes a satellite-motion-and-receiver-clock-correction module, a compute-predicted-range-and-delta-range module, a subtractor, and delta-range-difference-detection logic. The satellite-motion-and-receiver-clock-correction module periodically inputs, from a global navigation satellite system (GNSS) receiver, a carrier phase range for a plurality of satellites. The satellite-motion-and-receiver-clock-correction module outputs a corrected-delta-carrier-phase range for a current epoch to a first input of a subtractor. The compute-predicted-range-and-delta-range module outputs a predicted delta range to a second input of the subtractor. The predicted delta range is based on inertial measurements observed for the current epoch. The subtractor outputs a difference between the corrected-delta-carrier-phase range and the predicted delta range for the current epoch to delta-range-difference-detection logic.

  • Publication number: 20150241220
    Abstract: Systems and methods for filtering GNSS-Aided navigation data for helping combine sensor data and a priori data are provided. In at least one embodiment, the method comprises identifying an un-smoothed navigation solution inclusive of a navigation system reset, wherein a value is associated with the navigation system reset. The value associated with the navigation system reset is then subtracted from the un-smoothed navigation solution to generate an initial navigation solution. Further, the value associated with the navigation system reset is incrementally added to the initial navigation solution at a configurable rate to generate a smoothed navigation solution.
