Abstract
A system having a primary inertial measurement unit and a secondary inertial measurement unit configured to generate a primary position signal and a secondary position signal respectively is provided. The system also includes an error detection module communicably coupled to the primary inertial measurement unit and the secondary inertial measurement unit. The error detection module is configured to receive the primary position signal and the secondary position signal and detect if an out-range error is present in at least one of the primary position signal and the secondary position signal. The error detection module is also configured to detect if an in-range error is present in at least one of the primary position signal and the secondary position signal and determine an action to be performed based on the presence of at least one of the out-range error and the in-range error.
