The form of the algorithm used requires a linearized error form of the navigation state equations therefore, several error representations are presented. These sensed accelerations and rates are provided by inertial sensors described in Chapter 6.ДЄn integrated navigation system combines data from navigation states generated by these dynamic equations with independently obtained redundant data in a Kalman filter algorithm. In developing these equations, the objective is to form them in terms of sensed accelerations and rates, rather than as applied and reactionary forces and moments, as in the case of forming dynamic equations of motion. The resulting differential equations are nonlinear. The mathematical forms for these two mechanizations differ slightly therefore, only equations describing a strap-down mechanization are presented in detail.Д®quations describing navigation states (position, velocity, and attitude) for strap-down navigation system implementation referenced to a local level navigation frame are developed. Most current navigation systems use strap-down sensors mechanized as a strap-down navigator. Inertial navigation systems for terrestrial navigation can be, and have been, mechanized in either a gimballed platform or as a strap-down unit.

Perturbation form of navigation system error equations. Each specialty is identified by a 5-digit Air Force Specialty Code (AFSC). These long-range navigation systems predate GNSS and now act as a backup, as they don't share the common failure modes of the different GNSS systems. Section 9.1 describes the point-source systems: nondirectional beacons (NDBs), VOR, and DME, while Section 9.2 describes Loran. Local level navigation frame mechanization equations. Terrestrial radio navigation history is summarized in Section 1.3.1. In this chapter, the following is presented for an integrated terrestrial navigation system:
