Introduction to GNSS : Hexagon : 9780981375410 : 0981375413 : 28 Mar 2023 : Global Navigation Satellite Systems (GNSS) provide accurate positioning, navigation and timing (PNT) information for industrial, consumer and military applications. This book provides a primer for students and professionals looking to understand the basic concepts behind GNSS and how they enable autonomy. Easy-to-read descriptions and illustrations of how GNSS signals and information are used for PNT provide the reader with a solid foundation of GNSS fundamentals. Topics covered include the equipment required, sources of GNSS error and correction techniques, and threats to GNSS signals and mitigation solutions. The book also includes how GNSS is combined with other sensor technologies such as inertial navigation systems (INS), laser (LiDAR), sound (radar) and vision (cameras) to enhance navigation and situational awareness for autonomy.
