Chapter 17, New Signals and Future Systems

By Tony Pratt

The United States' GPS satellites are no longer the only navigation satellites orbiting the Earth, nor are the modern GPS satellites the same as their trail-blazing predecessors. Soon the skies will be filled with numerous new signals from several independently operated constellations. Chapter 17 reviews many of the new systems and signals that have already or will soon appear and discusses the underlying theory and technical details of how the many new features have been designed. Of interest to many GNSS users is how all the new systems will interact, and possibly interfere with one another. With this in mind, this chapter includes a significant practical discussion that allows readers to assess the potential levels of interference between systems, and thus to explore mitigation methods.
