  A hobbyist built a low-cost, DIY plane spotting system using a Raspberry Pi, a software-defined radio (SDR), and a homemade antenna. This setup receives ADS-B signals broadcast by aircraft, allowing him to track planes in real-time and display their information on a local map. The project, called "PiLane," leverages readily available and affordable components, making it accessible to other enthusiasts. The website details the build process, software used, and provides links to the project's source code.

  A software engineer, driven by a fascination with aviation and a desire to understand the air traffic patterns above their San Francisco Bay Area residence, has meticulously documented the creation of a personal, at-home aircraft tracking system. This endeavor, christened "PiPlane," utilizes a Raspberry Pi 4 microcomputer as its central processing unit. The system leverages software-defined radio (SDR) technology, specifically employing a low-cost RTL-SDR dongle to receive unencrypted ADS-B signals broadcast by aircraft equipped with transponders. These signals, which contain crucial data such as aircraft identification, altitude, and GPS coordinates, are then decoded and processed.

  The software component of the project employs readily available open-source tools. "Dump1090," a popular utility for decoding ADS-B signals, captures the raw data from the SDR. This information is subsequently fed into a custom-written Python script, crafted by the engineer. The script's primary function is to enhance the received data by enriching it with supplementary information gleaned from external sources, including aircraft registration details and photographs retrieved through API calls to publicly accessible aviation databases.

  The processed and augmented aircraft data is visualized on a user-friendly web interface, also developed by the engineer. This interface provides a real-time, dynamic display of air traffic within the system's reception range. Aircraft are depicted as icons overlaid on a map, with each icon providing detailed information about the corresponding aircraft upon selection. This includes not only the basic ADS-B data, but also the added details such as the aircraft's type, operator, and even a photograph. Furthermore, historical flight data is stored, allowing the user to review past air traffic activity.

  The project documentation meticulously details every step of the system's construction, from the hardware assembly and software installation to the intricacies of the custom Python script and web interface. This detailed documentation serves as a comprehensive guide for anyone interested in replicating the project. The creator emphasizes the accessibility and affordability of the components involved, positioning PiPlane as a viable undertaking for other aviation enthusiasts and hobbyists with a modest technical background. The entire project embodies a practical application of software-defined radio and data processing techniques to satisfy a personal curiosity and achieve a tangible, functional outcome.
