Global navigation satellite systems (GNSS) are widely used today in applications ranging from the familiar SatNav in cars, to aircraft, spacecraft and shipping navigation. The available technologies have improved rapidly in recent decades, and exciting new advances are continually being made. This book seeks to bring the reader up to date on the current state of the field, as well as outlining and evaluating new advances. In the first part, issues in the development of GNSS from stellar navigation to the ubiquitous present-day systems are considered. Topics discussed include receiver biases in GPS ranging, L1 GPS tools to monitoring bridge behaviour, and GNSS applications in intelligent traffic systems. Part two considers GNSS from the perspectives of signal, theory and applications. Here, the reader will gain new insights into subjects such as high sensitivity techniques, GPS positions geometry and analytical accuracy, ionospheric propagation effects on GNSS signals, and a novel decision-rule topological map-matching algorithm. The book collects research from authorities worldwide to give a diverse picture of GNSS today, and it will be an excellent resource for readers at student and advanced levels in the field.
