Inertial Navigation System (INS)

An Inertial Navigation System (INS) is a technology used to determine the position and movement of an object, such as an aircraft or ship, without relying on external signals like GPS. It uses sensors like accelerometers and gyroscopes to measure changes in speed and direction. By calculating these movements from a known starting point, the system continuously updates its location and trajectory. INS is particularly useful in environments where GPS is unavailable, allowing for precise navigation in various applications, including aviation, spacecraft, and submarines.
