Inertial navigation

Inertial navigation is a technique used to determine the position, orientation, and velocity of a moving object without the need for external references. It relies on an inertial measurement unit (IMU), which typically comprises accelerometers and gyroscopes to measure the object's acceleration and angular velocity, respectively. Here's how inertial navigation works: 1. **Acceleration Measurement**: Accelerometers detect changes in velocity by measuring the net acceleration of the object in different directions.
