Inertial Navigation Systems
An inertial navigation system (INSAn INS or Inertial Navigation System - sometimes used synonomously with IMU is a device used to measure a vehicle's speed, position, velocity, heading and orientation by using an accelerometer and a gyroscope.) is a high-tech navigator using motion and rotation sensors alongside a computer to figure out where something is, how it’s moving, and how fast. By using dead reckoning, the INS method for knowing positioning, it continuously calculates an object’s position and orientation based on its initial location. This allows users in airplanes, submarines, or even spacecrafts to guide and keep track of their location without signals such as GPSGlobal Positioning System is a navigation satellite system.
