  • Systems and methods for model based vehicle navigation
    Patent number: 11790793
    Abstract: Systems and methods for model based vehicle navigation are provided. In one embodiment, a navigation system: a strapdown navigation processor; a propagator-estimator filter, the navigation processor configured to input inertial sensor data and navigation corrections from the filter to generate a navigation solution comprising a vehicle velocity estimate and a vehicle attitude estimate; a vehicle physics model configured to perform calculations utilizing dynamics equations for a rigid body. The model inputs 1) vehicle state estimates from the navigation solution and 2) platform inputs indicative of forces acting on a vehicle platform. The model outputs a set of three orthogonal predicted translational acceleration measurements based on the inputs.

  • Integrated inertial gravitational anomaly navigation system
    Patent number: 11268813
    Abstract: A system implementing a method for generating a navigation output is provided. The method includes determining a gravitational anomaly estimate based at least in part on inertial sensor data and navigation output; generating navigation and sensor corrections that are due at least in part on inherent sensor errors that include vertical accelerometer/gravimeter corrections from at least a navigation output estimate, the gravitational anomaly estimate, and the gravity map data; and generating the navigation output based on the inertial sensor data, gravity map data and the navigation and sensor corrections.
