Abstract
Systems and methods for a tightly coupled trajectory predictor with constant up-finding are provided. In certain embodiments, a system includes an inertial measurement unit that provides inertial measurements of a vehicle. The system also includes an up-finding sensor that provides up-finding measurements based on when a portion of the vehicle is pointing up. Further, the system includes one or more processors that bound errors from the inertial measurements in a navigation solution during navigation of the vehicle using the up-finding measurements.
Claims20
A system comprising:
- an inertial measurement unit that provides inertial measurements of a vehicle;
- an up-finding sensor that provides up-finding measurements based on when a portion of the vehicle is pointing up;
- and
- one or more processors that bound errors from the inertial measurements in a navigation solution during navigation of the vehicle using the up-finding measurements.
A method comprising:
- receiving inertial measurements for motion of a vehicle;
- providing up-finding measurements based on detections of when a portion of the vehicle is facing a particular direction during the motion of the vehicle;
- and
- calculating an integrated navigation solution for the vehicle using the inertial measurements and the up-finding measurements, wherein the up-finding measurements provide a bound for errors in the inertial measurements.
A system comprising:
- an inertial measurement unit that provides inertial measurements of a vehicle;
- an up-finding sensor that provides up-finding measurements based on when a portion of the vehicle is pointing up;
- and
- one or more processors configured to:
- implement a model-based trajectory predictor, wherein the model-based trajectory predictor calculates trajectory predictions based on the up-finding measurements;
- and
- bound errors in the inertial measurements during navigation of the vehicle using the trajectory predictions.
