Latest Patents

One of Langel's latest patents is the "Wiener-based method for spoofing detection." This invention involves an apparatus that performs spoof detection of satellite signals based on clock information derived from those signals. The apparatus includes a position, velocity, time (PVT) component that derives clock information from satellite signals and provides it to a spoof detection mechanism. In some embodiments, the clock frequency estimate is modeled as a Wiener process.

Another notable patent is titled "System and methods for fault detection in Kalman filter estimation." This invention provides systems and methods for detecting faults in estimator data. In one or more examples, measurements from various data sources are received. The received data is used to calculate an innovation, which can represent the difference between the received data and an expected value. The innovation generates a test statistic that is accumulated at multiple monitors, each configured to accumulate the test statistic over varying periods. If the accumulated test statistic exceeds a predefined threshold, the system alerts the user that the received data may be faulty.
