In this project, we use several techniques and concepts to simulate software-defined transmitter/receiver systems through an aviation rf receiver use case. This version of the project plays a passive role. The SDR component is an RF receiver node to collect and transform broadcast messages into DIS messages to produce a 'home aviation spotter' awareness system.
The system is composed of a few parts:
A software-defined radio setup [1] with a compiled FPGA image and PDU transmitter source code [2] to receive ADS-B data [3]
A conversion model for transforming message traffic in the DIS PDU Entity State messages

A watch system to visualize DIS broadcasts and alerts when variables are within tolerance for conditions of interest.
