Abstract: Global Positioning System (GPS) technology has revolutionized the domain of autonomous robotics by enabling precise navigation in both outdoor and partially indoor environments. This paper explores how GPS integrates with robotic systems to provide real-time location tracking, path planning, and autonomous mobility. Through detailed analysis of satellite-based navigation, differential GPS, and hybrid sensor integration, the study investigates the techniques by which robots interpret GPS data and make autonomous decisions in complex environments. The role of GPS in agricultural bots, delivery drones, and exploration rovers is discussed in depth, along with limitations such as signal obstructions and accuracy challenges in urban canyons or dense forests. Additionally, this paper outlines strategies like GPS-IMU fusion and SLAM (Simultaneous Localization and Mapping) to overcome these challenges. With growing reliance on mobile robots in daily life and industrial processes, understanding GPS-based navigation is critical for advancing robotics applications.
Keywords: GPS, autonomous robots, localization, navigation, differential GPS, satellite systems, robotics path planning.
