GPS tracking modules are electronic devices that use satellite-based positioning systems to determine and monitor the exact location of objects, vehicles, or individuals. These modules rely on signals from global navigation satellite systems (GNSS), such as GPS (Global Positioning System), to calculate coordinates like latitude, longitude, and altitude.
A typical GPS tracking module includes a receiver, antenna, microcontroller, and communication interface. It collects signals from satellites, processes them, and then transmits location data to a server, mobile application, or monitoring system.
These modules exist because of the growing need to track movement and location in real time. They are widely used in transportation, logistics, agriculture, wearable devices, and smart city systems. Over time, advancements in wireless communication such as 4G, 5G, and IoT networks have improved the accuracy and responsiveness of these systems.
