Stratux
An open-source ADS-B receiver for aviation weather and traffic data using RTL-SDR and Raspberry Pi.
What is Stratux?
Stratux is an open-source aviation receiver that provides pilots with real-time weather and traffic information using affordable hardware. It creates a portable ADS-B station that integrates with popular electronic flight bag (EFB) applications, enhancing situational awareness in the cockpit. The project is built on a Raspberry Pi with common RTL-SDR devices for a modular and customizable hardware setup.
Pilots and aviation enthusiasts seeking an affordable, portable ADS-B receiver for in-flight situational awareness. It is also suitable for developers interested in open-source aviation technology and hardware tinkering.
Developers choose Stratux for its open-source, community-driven approach that makes advanced aviation technology accessible and affordable. Its unique selling point is the modular hardware design using Raspberry Pi and RTL-SDR devices, allowing for easy customization and integration with a wide range of popular EFB applications.
Overview
Aviation weather and traffic receiver based on RTL-SDR.
Use Cases
Best For
- Building a portable, dual-band ADS-B receiver for general aviation aircraft.
- Pilots needing real-time weather and traffic data integration with EFB apps like ForeFlight or FlyQ EFB.
- Aviation hobbyists seeking an open-source, customizable alternative to commercial ADS-B receivers.
- Enhancing situational awareness in the cockpit with AHRS (Attitude and Heading Reference System) support.
- Creating a cost-effective ADS-B ground station for flight tracking or data collection.
- Developers or tinkerers interested in modifying or extending aviation receiver hardware and software.
Not Ideal For
- Pilots requiring FAA-certified, plug-and-play equipment for instrument flight rules (IFR) operations.
- Users needing immediate professional customer support, warranties, or guaranteed uptime.
- Projects where minimal hardware assembly and software configuration are critical priorities.
Pros & Cons
Pros
Captures both 978 MHz UAT and 1090 ES ADS-B signals, providing comprehensive air traffic and weather data as highlighted in the key features.
Integrates with numerous popular electronic flight bag applications like ForeFlight, FlyQ EFB, and WingX Pro7, listed explicitly in the README.
Built on Raspberry Pi with common RTL-SDR devices, allowing for easy customization and upgrades, per the project's philosophy.
Maintained by developers like b3nn0 with active Discord and Reddit communities, ensuring ongoing updates and support as noted in the history section.
Cons
The cyoung branch is no longer maintained, requiring users to switch to the b3nn0 branch for active development, which can lead to confusion and migration effort.
Unlike commercial receivers, it requires sourcing and assembling Raspberry Pi and RTL-SDR components, making setup more time-consuming and error-prone.
As noted in the README, newer Raspberry Pi models like 3B+ and Pi 4B use significantly more power, which can be a drawback for portable aviation use.
