This chapter discusses positioning and navigation. The chapter looks at the characteristics of positioning systems as a whole. The reader is able to see how the satellite positioning techniques used in the Global Positioning System, which is a Global Navigation Satellite System (GNSS), compare to those techniques used in terrestrial positioning systems. Positioning and navigation systems exist for land, sea, and air applications and different technologies suit different applications. Some of the error modeling carried out on terrestrial positioning systems contributes to GNSS error modeling. Algorithms for improved positioning are a subject of active research. As research progresses, users will be able to move between positioning technologies seamlessly. |
