nav: Navigational Location and Attitude

On sea-based mobile ARM deployments, several instruments depend on the ship’s current position and “attitude”. The NAV system reads the ship’s current position (latitude and longitude) as well as its “attitude” (roll, pitch, and yaw angles). This data is collected for both near-real-time and post-deployment processing of instrument data.
