| Popis: | This chapter includes a number of topics. One of these looks at the planned accuracy and precision, of positioning, with which Global Positioning System (GPS) was designed to work. Another topic is the natural effects that GPS signals are subjected to, such as relativity. Mention is also made of some abnormal natural effects that can occur, such as a solar maximum. When a solar maximum occurs it results in ionospheric scintillation and this adversely affects the signal to noise ratio. Differential GPS, which is a means of improving position accuracy by using additional data, is discussed. The chapter also shows how the Earth is modeled. |
