What is INS?

INS stands for Inertial Navigation System. It is a self-contained navigation technology that uses accelerometers and gyroscopes to continuously track an object's position, orientation, and velocity without the need for external references like GPS. INS is commonly used in aircraft, ships, submarines, spacecraft, and guided missiles. It's particularly useful in environments where GPS signals are unavailable or unreliable, such as underwater or in areas with heavy jamming.
