The system uses a combination of dead reckoning and Kalman filtering to calculate the position and velocity of the vehicle. Dead reckoning is the process of using the initial position and velocity of the vehicle and integrating the accelerometer and gyroscope measurements to estimate the position and velocity of the vehicle over time. Kalman filtering is a method of estimating the state of a system using a mathematical model and measurement data.

Inertial navigation systems have several advantages over other navigation methods, such as being relatively independent of external factors, such as GPS signal availability, providing accurate navigation in areas where GPS signals are weak or absent, and providing continuous navigation even when the GPS signals are lost.
