When a GPS receiver reports its position to a monitoring center using a radio signal of some kind, how do we know that the receiver or its associated communications unit is telling the truth? It’s not that difficult to generate false position reports and mislead the monitoring center into believing the receiver is located elsewhere — unless an authentication procedure is used. In this month’s column, we look at the development of a clever system that uses the concept of supplicant and authenticator to assess the truthfulness of position reports.

And, this trend promises to continue in the foreseeable future. Placing emphasis on applications development, this unique resource offers a highly practical overview of GNSS (global navigation satellite systems), including GPS. The applications presented in the book range from the traditional location applications to combining GNSS with other sensors and systems and into more exotic areas, such as remote sensing and space weather monitoring. Written by leading experts in the field, this book presents the fundamental underpinnings of GNSS and provides you with detailed examples of various GNSS applications. Moreover, the software included with the book contains valuable processing tools and real GPS data sets to help you rapidly advance your own work in the field. You will find critical information and tools that help give you a head start to embark on future research and development projects.
