Chapter 9, Combining GNSS with RF Systems

By Richard Fuller

We live in a world awash with RF signals, and they all contain some information that can be exploited for navigation. Chapter 9 explores the topic of combining GNSS with other RF systems for the navigation and tracking of vehicles, personnel, and assets. Chapter 9 first discusses the basics of RF signal propagation and then considers the motivation for combining various RF signals with GNSS.
The chapter then provides examples of currently available RF signals that can be exploited for this application and presents filtering and sensor fusion algorithms for combining RF signals with GNSS. The chapter then closes by describing the applications that use the integration scheme discussed in this chapter.

A spreadsheet and MATLAB/Octave scripts are provided that demonstrate basic RF antenna computations as well as Doppler and K-Nearest Neighbor estimation techniques.
