Which type of navigation system does not rely on radio wave reception and uses gyros and accelerometers to calculate position?

The answer is accurate because an Inertial Navigation System (INS) operates independently of external signals and utilizes internally measured data to determine the position, orientation, and velocity of an aircraft. This is accomplished through a combination of gyroscopes, which help in maintaining the angular position, and accelerometers, which measure linear acceleration. By continuously integrating these measurements over time, the INS can calculate the current position of the aircraft relative to a predetermined starting point.

In contrast, a Global Positioning System (GPS) relies on satellite signals to determine location, which directly contrasts with the internal data processing of an INS. Similarly, a Radio Navigation System depends on external radio waves for navigation, and Terminal Area Navigation, often used in approach phases, also utilizes various external references. Thus, the self-contained nature of inertial navigation makes it unique among navigation systems, confirming that it does not rely on radio wave reception.
