Abstract
Present novel and non-trivial system, device, and method for generating geographic position are disclosed. A processor receives navigation data representative of geographic position from an external source such as a global positioning system (“GPS”); receives navigation data representative of measurements of angular and linear motions from an internal source of navigation data such as an inertial measurement unit (“IMU”); and determines and generates navigation data representative of geographic position responsive to such determination. The generation of navigation data could be based upon internal source navigation data and an estimate of error of geographic position, where the estimate of error is based upon a delay of the external-sourced navigation data and a delayed output from one of the internal sources (e.g., delayed output of an IMU).
