What is the primary output of an INS system in determining position?

• A. Ground speed
• B. Time
• C. Distance traveled
• D. Magnetic heading

Answer: (B)

The primary output of an Inertial Navigation System (INS) in determining position is indeed related to time; specifically, it's the system's ability to calculate position based on the time that has elapsed since the last known position, combined with data on velocity and direction of travel. An INS utilizes accelerometers and gyroscopes to detect changes in motion and orientation; these measurements allow it to compute the aircraft's position by integrating the acceleration data over time. While ground speed, distance traveled, and magnetic heading are relevant outputs or parameters that can be derived from an INS, they are not the primary outputs for determining the position itself. Ground speed is a measure of how fast the aircraft is moving over the ground, distance traveled refers to the total path covered, and magnetic heading indicates the direction the aircraft is facing relative to magnetic north. However, these parameters depend on the continuous calculation and integration of time and acceleration to establish the position. Thus, time is fundamentally essential for position determination in the context of an INS.
