Overall, inertial navigation is a method of determining a vehicle's position and velocity using measurements from accelerometers and gyroscopes. The system uses the laws of motion to calculate the position and velocity of a moving object by integrating the measurements from the sensors over time. It is relatively independent of external factors, such as GPS signal availability, it provides accurate navigation in areas where GPS signals are weak or absent, and providing continuous navigation even when the GPS signals are lost. However, it is important to note that the system has some limitations such as errors accumulation over time, the need for regular calibration and alignment, and sensitivity to temperature changes and vibrations.
