Step 5 — Application

Once the errors have been accounted for in the GNSS equation, the receiver can determine its position and time and pass this information on to the end-user application. The GNSS technology market is a ubiquitous, multi-billion-dollar industry. Applications range from simple hand-held metre-level (yard-level) navigation aids to robust, centimetre-level (inch-level) positioning solutions for survey, military and autonomous applications. With users demanding GNSS positioning functionality in increasingly challenging environments, GNSS technology is being integrated with other sensors such as inertial technology to enhance positioning capabilities and dependability. We look at a variety of sensors in Chapter 6.

As applications become more complex and ubiquitous, the likelihood of “GNSS denied” scenarios, such as jamming and spoofing, increases, whether intentional or unintentional. Chapter 7 discusses the causes and mitigation techniques of GNSS denial. Our final chapter, Chapter 9, promises to inspire with some of our most exciting customer applications.
