Abstract
A system is provided. The system includes a perception sensor, a first inertial measurement unit and a first localization module. The first localization module is configured to generate a first position estimate signal indicative of an estimated position of the machine. The system includes a second inertial measurement unit and a second localization module. The second localization module is configured to generate a second position estimate signal indicative of the estimated position of the machine. A position determination module is communicably coupled to the first and second localization modules. The position determination module is configured to determine a health of the first and second localization modules based on one or more parameters indicative of errors associated with the first and second inertial measurement units respectively; and determine an estimated position of the machine based on the determined health of the first and second localization modules.
