Abstract
A method of operating a vehicle includes navigating the vehicle along a path, collecting a set of navigation parameters of the vehicle from at least one of a sensor, a global positioning system, or an inertial reference system, determining a set of statistical uncertainties related to at least some navigation parameters in the set of navigation parameters, and associating a set of statistical weights to the at least some navigation parameters.
Claims19
A method of operating a vehicle, the method comprising:
- collecting a set of navigation parameters of the vehicle from at least one of a sensor, a global positioning system, or an inertial reference system;
- applying a correction to each navigation parameter in the set of navigation parameters to determine a corresponding set of preliminary navigational solutions;
- determining a statistical uncertainty corresponding to each preliminary navigational solution in the set of preliminary navigational solutions to define a set of statistical uncertainties;
- associating a statistical weight to each navigation parameter in the set of navigation parameters, based on the set of statistical uncertainties, to define a set of statistical weights;
- blending the set of preliminary navigational solutions, based on the set of statistical weights, to determine a single navigational solution for the vehicle;
- and
- operating the vehicle in accordance with the single navigational solution.

A method of operating an aircraft, the method comprising:
- collecting a set of navigation parameters of the aircraft from at least one of a sensor, a global positioning system, or an inertial reference system;
- applying a correction, by way of a Kalman filter, to each navigation parameter in the set of navigation parameters to determine a corresponding set of preliminary navigational solutions;
- determining a set of errors for the set of preliminary navigational solutions;
- determining, by a covariance matrix, a statistical uncertainty for each error in the set of errors to define a set of statistical uncertainties;
- associating a statistical weight to each navigation parameter in the set of navigation parameters, based on the set of statistical uncertainties, to define a set of statistical weights;
- blending the set of preliminary navigational solutions, based on the set of statistical weights, to determine a single navigational solution for the aircraft;
- and
- operating the aircraft in accordance with the single navigational solution.
