After more than five years of hard work by 131 authors from 18 countries, “Position, Navigation, and Timing Technologies in the 21st Century” (“PNT21”) is finally ready to meet the readers. Published by Wiley-IEEE Press, and written by world-renowned experts, PNT21 offers uniquely comprehensive coverage of the latest developments in the field of PNT .

PNT21 is a two-volume set containing 64 chapters organized into six parts. Volume 1 focuses on satellite navigation systems, technologies, and applications. It starts with a historical perspective of GPS and other related PNT development. Vol 1 Part A consists of 12 chapters on fundamentals and latest developments of global and regional satellite navigation systems (GNSS and RNSS), the need for their coexistence and mutual benefits, signal quality monitoring, satellite orbit and time synchronization, and satellite- and ground-based augmentation systems that provide information to improve the accuracy of navigation solutions. Part B contains 13 chapters on recent progress in satellite navigation receiver technologies such as vector processing, assisted and high sensitivity GNSS, precise point positioning (PPP) and real time kinematic (RTK) systems, direct position estimation techniques, and GNSS antennas and array signal processing. Also: the challenges of multipath-rich urban environments, in handling spoofing and interference, and in ensuring PNT integrity. Part C finishes the volume with 8 chapters on satellite navigation for engineering and scientific applications. A review of global geodesy and reference frames set the stage for discussions on the broad field of geodetic sciences, followed by a chapter on GNSS-based time and frequency distribution. Three chapters are dedicated to severe weather, ionospheric effects, and hazardous event monitoring. Finally, comprehensive treatments of GNSS radio occultation and reflectometry are provided.

Volume 2 addresses PNT using alternative signals and sensors and integrated PNT technologies for consumer and commercial applications. An overview chapter provides the motivation and organization of the volume, followed by a chapter on nonlinear estimation methods which are often employed in navigation system modeling and sensor integration. Vol 2 Part D devotes 7 chapters to PNT from various radio signals-of-opportunity transmitted from sources on the ground, from aircraft, or from low Earth orbit (LEO) satellites. In Part E, there are 8 chapters covering a broad range of non-radio frequency sensors operating in passive and active modes to produce navigation solutions, including MEMS inertial sensors, advances in clock technologies, magnetometers, imaging, LiDAR, digital photogrammetry, and signals received from celestial bodies. A tutorial-style chapter on GNSS/INS integration methods is included in this Part E. Also included in Part E are chapters on the neuroscience of navigation and animal navigation. Finally, Part F presents a collection of contemporary PNT applications such as surveying and mobile mapping, precision agriculture, wearable systems, automated driving, train control, commercial unmanned aircraft systems, aviation, satellite orbit determination and formation flying, and navigation in the unique Arctic environment.

Because of the diverse authorship and topics covered in PNT21, the chapters were written in a variety of styles. Some offer high-level reviews of progress in specific subject areas, while others are tutorials. A few chapters include links to MatLab or Python example code as well as test data for readers who desire hands-on practice. The collective goal is to appeal to industry professionals, researchers, and academics involved with the science, engineering, and application of PNT technologies. A website (pnt21book.com) provides downloadable code examples, data, homework problems, select high-resolution figures, errata, and a way for readers to provide feedback.
