Mohinder Grewal, professor emeritus of electrical engineering, published a chapter in “Remote Sensing Handbook, Volume I, Sensors, Data Normalization, Harmonization, Cloud Computing and Accuracies,” which is edited by Prasad S. Thenkabail and Taylor Francis Books.
Grewal’s chapter, “Global Navigation Satellite Systems (GNSS) Theory and Practice: Evolution, State of the Art and Future Pathways,” is part of “Part II: Global Navigation Satellite Systems GNSS and Their Characteristics.” The chapter covers the four satellite systems — GPS, GLONESS, Galileo and Compass (BeiDou2) — and the space-based augmentation systems of various countries, which reduce errors and enhance safety.
The “Remote Sensing Handbook” abstract reads: “This thoroughly revised and updated volume draws on the expertise of a diverse array of leading international authorities in remote sensing and provides an essential resource for researchers at all levels using remote sensing.”
