In the context of inertial navigation systems, what function does a potentiometer serve?

Inertial navigation systems rely on various sensors to determine the position and movement of a vehicle. A potentiometer is utilized in this context as a device that can measure angular displacement or rotation. Specifically, it serves to gauge the orientation of the system relative to a reference point.

The measurement of gravity forces is paramount for inertial navigation, as these systems must account for the gravitational pull affecting their orientation and trajectory. Potentiometers assist in capturing changes in angular position, which can then be used to infer the effects of gravitational forces on the system's navigation calculations. By accurately measuring orientation, the potentiometer helps provide essential data that contributes to maintaining accurate inertial navigation.

In contrast, measuring velocity, acceleration, or air pressure typically involves different types of sensors, such as accelerometers for acceleration, GPS for velocity, and barometers for air pressure, which do not perform the same function as a potentiometer in the context of inertial navigation systems.
