Originally a military tool developed by the US Navy, GPS technology has evolved into a widely accessible system due to advancements in satellite technology and the proliferation of mobile and web applications. This tutorial guides users on integrating GPS capabilities into a Raspberry Pi project using a GPS Module Breakout and the PubNub Geolocation APIs via the PubNub Python SDK. The process involves setting up the hardware, enabling necessary interfaces like UART, I2C, and SPI, and configuring Python and CircuitPython libraries to retrieve GPS data in real-time. The tutorial also demonstrates how to visualize GPS data using Google Maps API, allowing users to track and display location information graphically in a browser. The project is designed to be flexible, incorporating optional LTE connectivity for GPS functionality independent of WiFi, and provides step-by-step instructions for hardware setup, software configuration, and real-time data visualization.
