This chapter presents the basic fundamentals, classifications, and features of navigation systems. It describes the two most popular navigation systems: inertial navigation system; and Global Positioning System (GPS). The chapter also reviews some related topics such as coordinate systems, world geodetic system, avionics, gyroscope, and filtering in brief. In designing navigation system for a UAV, one must select the type of navigation system, select the navigation devices, sensors, and then conduct calculations, simulation, and analysis. The design of the navigation system is conducted in parallel to the design of guidance and control systems. It is highly recommended to examine the performance of the navigation system by implementing in a hardware (for instance, on a single board computer) before testing in a real flight test. The inertial navigation is a low cost system, but provides less accurate data; hence it requires frequent checking of position from other sources such as GPS.
