GPS (Global Positioning System) is a technology that represents one of the most important applications of GNSS(Global Navigation Satellite Systems), providing essential positioning, navigation, and timing services worldwide.It has informations about the main GNSS systems: GPS (United States of America), Galileo (European Union), GLONASS (Russia), and BeiDou (China) presenting their characteristics, evolution, and accuracy. It also shows the practical applications of GNSS receivers in many fields: automotive transport, aviation, maritime navigation, and industrial activities:transportation,logistics,drones and robotics,precision agriculture, construction, and mining. The study emphasizes the role of GNSS technology in optimizing routes, increasing safety and efficiency, and supporting autonomous driving. ,it examines the concept of the GNSS SSV (Space Service Volume) , which extends GNSS services to altitudes between 3,000 and 36,000 km, ensuring the operation of space navigation systems. It provides detailed information about location helping you to find the place or finish the job faster. There are six GEO satellites and are part of the equatorial orbital plane,60 degrees in longitude or four hours in time. GEO and MEO orbits are almost in phase with each other. The conclusions that the global use of GPS technology contributes to the development of smart infrastructures, transportation safety, and scientific progress, demonstrating the essential role of GNSS in the modern society,helping you saving time.
