FILTERING GNSS-AIDED NAVIGATION DATA TO HELP COMBINE SENSOR AND A PRIORI DATA

摘要

Systems and methods for filtering GNSS-Aided navigation data for helping combine sensor data and a priori data are provided. In at least one embodiment, the method comprises identifying an un-smoothed navigation solution inclusive of a navigation system reset, wherein a value is associated with the navigation system reset. The value associated with the navigation system reset is then subtracted from the un-smoothed navigation solution to generate an initial navigation solution. Further, the value associated with the navigation system reset is incrementally added to the initial navigation solution at a configurable rate to generate a smoothed navigation solution.

1. A method for improving a navigation solution, the method comprising:
identifying an un-smoothed navigation solution inclusive of a navigation system reset, wherein a value is associated with the navigation system reset; subtracting the value associated with the navigation system reset from the un-smoothed navigation solution to generate an initial navigation solution; and incrementally adding the value associated with the navigation system reset to the initial navigation solution at a configurable rate to generate a smoothed navigation solution.
