Global Navigation Satellite Systems (GNSSs) have become an essential technology used in navigation, positioning, and timing applications in meteorology, environmental monitoring, disaster management, and space exploration. This comprehensive book explores the various applications of GNSS technology in different fields of Earth and Space observations and provides researchers, professionals, and students valuable insights into these emerging trends. It discusses the challenges that impact the performance of GNSS technology and offers solutions through several case studies on Space weather and climate disasters, opening a different dimension of approaches in various paradigms of GNSS technology. Features:Covers the most up-to-date GNSS applications in three major areas related to Earth and Space observations: climate studies, disaster management, and Space weather monitoringIncludes case studies of best practices in climate studies and disaster managementExplains the impacts of Space weather events on the near-Earth environmentDescribes limitations and future possibilities of better use of GNSS in Earth and Space observation and monitoringHighlights an integrated and interdisciplinary approach valuable to a wide range of readers studying Earth and Space interactionsThis book is a valuable resource for professionals, researchers, academics, and students in Remote Sensing and GIS, Earth Science, Physics and Electronics, Climate Studies, Disaster Management, Geophysics, and Space Science.
