Inertial Guidance: A Complete Guide

Inertial Guidance is a navigation method that allows an object—such as a missile, aircraft, spacecraft, or even a robot—to determine its position and orientation without the need for external references like GPS, radar, or beacons. It relies on inertial sensors, such as gyroscopes and accelerometers, to measure changes in velocity and direction, which are then used to calculate the object’s position and trajectory.
