Chapter 4 discusses generic DGNSS systems and provides details on the use of
space-based augmentation systems, such as the WAAS used extensively in North
America. While there are no specific examples associated with
this chapter, the software receiver discussed in Chapter 5 is capable of making
WAAS ionosphere corrections as described in Chapter 4, thereby demonstrating a
simple DGNSS application using real data.
