INS. Inertial navigation is a self-contained navigation technique in which measurements provided by accelerom- eters and gyroscopes are used to track the position and orientation of an object relative to a known starting point, orientation and velocity.

Low-cost sensors are enabling a new generation of commercial navigation applications especially when aided with other sensors. Many approaches have been investigated to mitigate the poor performance of low-cost sensors, but few people have addressed the issue of the design process itself. , dead-reckoning.
