How to: 3DR Pixhawk and Sagetech ADS-B integration

News/adsbintegration.png

In January we published news that we completed test integration of 3DR copter with Sagetech XPS-TR transponder.

We have received permission from Sagetech to disclose part of their communication protocol in our source codes and can publish all technical information of the solution.

In our experimental project we used Arduino board as communication layer between autopilot and transponder.

Arduino sketch controls transponder mode and decodes telemetry from autopilot.

Source code and schematic available at GitHub - https://github.com/UgCS/sagetech-ardu

Operation of ADS-B solution was monitored using following methods:

- ADS-B receiver Sagetech Clarity + FlyQ EFB application

- Ground control software UgCS with ADS-B receiver support

- Webpage Flightradar24.com

During tests 3DR Quad showed on all types of receivers without interruptions. Thus UAV was seen by nearby air traffic and its presence made known to ensure airspace safety.

See a short video preview of a copter with an onboard ADS-B Transponder flying a route on autopilot set in UgCS.

We hope that our experience can help you if you want to reproduce same solution.

Safe flights,
UgCS team
