| Depth sensors are a crucial means to receive feedback about more than just depth. By using four high-precision depth sensors, pitch and roll of the submarine can be calculated. Pitch and roll information can then be used to validate any information provided by an inertial measurement unit, and it is especially useful because depth sensors are not prone to the error induced by motors that a magnetometer is. | Depth sensors are a crucial means to receive feedback about more than just depth.
