Strapdown Navigation

Strapdown navigation is a system that determines an object's position and movement without relying on external references. It uses sensors called gyroscopes and accelerometers attached directly to the moving platform—like an aircraft or missile—to continuously measure orientation, acceleration, and rotation. By integrating this data over time, the system calculates current position, velocity, and direction. Unlike traditional navigation that relies on external signals (like GPS), strapdown navigation is self-contained, making it useful in environments where signals are unavailable or unreliable. It requires sophisticated algorithms to process sensor data accurately, ensuring reliable navigation even under challenging conditions.
