This chapter describes the structure of Global Positioning System signals. On each of two frequencies, there is a carrier signal, and this is modulated by ranging code(s), as well as data. The two ranging codes are coarse/acquisition (C/A) and P(Y) c

The ranging codes for the Global Positioning System’s (GPS’s) legacy signals are C/A and L1 P(Y) (both broadcast on the L1 frequency) and L2 P(Y), broadcast on the L2 frequency. GPS is undergoing a process of modernization. This includes the addi

Using GPS alone may not give the desired positioning accuracy. Some applications require high accuracy, such as when an aircraft is landing. This chapter describes some ways of using additional information, that is, augmenting GPS, so as to produce a
