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 navigation aids, to robust, centimetre-level positioning solutions for survey, unmanned and military. 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 opportunity for GNSS denied scenarios, whether intentional or unintentional, increase. Chapter 7 discusses causes and mitigation techniques of GNSS denial such as jamming and spoofing. Our final chapter, Chapter 8 promises to inspire with some of our most exciting customer applications.
This has been a tough chapter and we’re pleased you persevered through the basics of GNSS positioning. Chapter 3 provides additional information about the GNSS constellations that have been implemented or are planned. Chapters 4, 5, 6 and 7 discuss advanced GNSS concepts, and Chapter 8 discusses equipment and applications—how the simple outputs of this incredible technology are being used.
