strapdown inertial navigation systems

Strapdown inertial navigation systems (INS) are advanced technologies used to determine the position and orientation of a moving object, like an aircraft or a spacecraft. Unlike traditional systems that use gimbals to keep sensors level, strapdown systems fix sensors directly onto the moving platform. They measure acceleration and rotation directly, and with complex algorithms, calculate the object's current position and direction. This technology is crucial for navigation in environments where GPS signals may not be available, making it essential for military, aerospace, and autonomous vehicles.
