Abstract: A system comprises a plurality of reference navigation systems, each reference navigation system configured to generate a respective reference navigation solution. The system also comprises a test navigation system, the test navigation system configured to generate a test navigation solution; and a processing unit configured to compare the test navigation solution to each of the respective reference navigation solutions to estimate one or more errors in the differences between the test navigation solution and the respective reference navigation solutions. The processing unit is further configured to update the respective reference navigation solutions to account for the corresponding one or more estimated errors. The processing unit is also configured to compare the test navigation solution to the updated reference navigation solutions to generate a performance score representative of the performance of the test navigation system.

Abstract: A method of determining an operational state of a navigation system of a platform is provided. The method comprises testing at least a portion of hardware in the navigation system. Additionally, a measurement of at least one navigation variable from an inertial sensor is combined with a measurement of another navigation variable. A plurality of residuals for the measurement of at least one navigation variable and the measurement of another navigation variable are determined with a blending filter. An error for the measurement of at least one navigation variable is estimated based on the plurality of residuals. The method also predicts an error for the measurement of at least one navigation variable while the navigation system is in route.
