Zusammenfassung:	A system that includes a high performance sensor to provide accurate measurements and at least one dissimilar sensor that is less accurate. The at least one dissimilar sensor is of a different type of sensor than the high performance sensor while providing a same type of measurement as the high performance sensor. The at least one dissimilar sensor has a longer life expectancy than the high performance sensor. An at least one controller is configured to start both the high performance sensor and the at least one dissimilar sensor at startup of the system, to turn off the high performance sensor after a select period of time, and to output measurement data based on measurements of the high performance sensor while the high performance sensor is on and output the measurement data based on the at least one dissimilar sensor when the high performance sensor is off.
