Latest Patents

One of Graham's notable patents is titled "Navigation integrity in GPS challenged environments." This patent outlines systems and methods for detecting degraded navigation sensors. The approach is based on a policy derived from a Partially Observable Markov Decision Process (POMDP). The navigation parameters derived from the sensors are provided to individual Kalman filters. Each filter's covariance indicates the probability of degradation of the sensor from which the navigation parameter is derived. The outputs of these Kalman filters are then provided to a master filter. This master filter is compared to a criterion to determine if there are signs of a degraded sensor. If such signs are present, the policy is consulted to identify which sensors are degraded. The consideration of degraded sensors when navigating a vehicle is inhibited, ensuring safer navigation.
