INS (Inertial Navigation System)

An Inertial Navigation System (INS) is a technology used to track the position and motion of a vehicle or object without relying on external signals, like GPS. It uses a combination of sensors, including accelerometers and gyroscopes, to measure movements—detecting changes in speed and rotation. By integrating this data over time, the system can calculate the current location and orientation. INS is commonly used in aircraft, submarines, and spacecraft, providing reliable navigation even in environments where other signals might be unavailable or unreliable.
