Inertial Navigation Systems (INSs) are modern, technologically sophisticated implementations of the age‐old concept of dead reckoning. There are two main types of INSs: gimbaled and strapdown. In a gimbaled system, the accelerometers are mounted on a platform that is rotationally isolated from the vehicle. This platform is maintained in a local‐level orientation so that there are two accelerometers in the horizontal plane for providing the data needed to compute horizontal velocity and position. Strapdown operation which will be assumed because modern processors are in no way challenged by the computational requirements. A variety of coordinate (or reference) frames are utilized in INSs. The most challenging aspect of initialization lies in the determination of the body‐to‐nav DCM. INSs are subject to a wide variety of errors. These include mounting errors, initialization errors, sensor errors, gravity model errors, and computational errors, all of which are briefly described.
