Raspberry Pi - SDR Standalone Decoder 

Demo: https://youtu.be/vytJKIJlaHo?si=VrTBUFP-C_sGmd5- 

Design problem:  Design and construct a standalone receiver device using Single Board Computer (SBC) hardware, such as the Raspberry Pi, combined with Software-Defined Radio (SDR) hardware. The device aims to decode at least one type of digital signal, we chose airplane signals. The system is headless, allowing the decoded data to be displayed on a separate device, such as a laptop.

Solution: The primary objective of decoding digital signals was achieved through the integration of readily available and cost-effective components. The project showcased the adaptability of Single Board Computer (SBC) technology, particularly the Raspberry Pi 4, in implementing sophisticated functionalities. The headless configuration, which allows data display on external devices, enhances the system's usability. Despite challenges, effective solutions were implemented, contributing to a valuable learning experience. Rigorous testing and validation procedures ensured the reliability and performance of the receiver device, laying a robust foundation for future developments.

Role: My responsibilities encompass selecting the optimal software decoder (Dump1090) and Raspberry Pi model to integrate with RTL-SDR, ensuring efficiency and compatibility. I configured both headless and decoder connections, requiring a keen understanding of network configurations. A crucial aspect of my role involves meticulous documentation of the entire process and outcomes, providing valuable insights for future reference and continuous improvement. In essence, I contribute to the seamless functioning of our technological infrastructure, ensuring optimal performance and reliability.
