Navigational systems is a rather large subject area. This chapter covers basic radio aids to navigation such as very-high-frequency (VHF) omnidirectional range (VOR), tactical air navigation (TACAN), nondirectional beacon (NDB), and distance measuring equipment (DME). It also covers self-contained navigational systems such as inertial navigation systems (INSs), Doppler navigation systems (DNSs), and the global positioning system (GPS). Additional topics of interrogate friend or foe (IFF), mode S, and data link are also addressed. This chapter also covers a brief discussion on long-range navigation (LORAN).
