Abstract: Systems and techniques to facilitate generating and/or encoding rotational data associated with a mechanical element are presented. A sensor system can measure rotational speed data and phase data associated with a mechanical element that rotates. The sensor system can also encode the rotational speed data and phase data into a digital data packet. Furthermore, the sensor system can transmit the digital data packet associated with the rotational speed data and phase data to one or more sensor devices in communication with the sensor system.

Abstract: Systems and methods for determining aircraft component phase position are provided. In one embodiment, a method can include receiving a set of data from a data acquisition system associated with a component. The method can include identifying a plurality of phase reference points based, at least in part, on the set of data.
