Chapter 11, Integrated GNSS and LORAN

By Sherman Lo and Ben Peterson

Chapter 11 discusses the integration of GNSS with the low-frequency radio navigation system known as LORAN. It is well-known that GNSS are susceptible to interference and jamming. Thus, as more and more users start relying on GNSS for various applications, ensuring that it is robust against interference and jamming has become very important. LORAN has emerged as one potential candidate system that can be integrated with a GNSS to enhance its robustness. Chapter 11 describes LORAN signals and receivers to facilitate this integration (especially safety-of-life applications) and discusses various integration architectures for these two systems and the trade-offs associated with these integration schemes. Finally, the issue of integrity is considered, which must be carefully considered when these two systems are used in applications with safety-of-life implications.
