Assemble and modify your Stratux (OGN) Flarm anti-collision system right.

Build your own Flarm-compatible Stratux anti-collision system – view our comprehensive DIY component list, or
Upgrade your current Stratux with AHRS or barometric pressure sensor, even when you use a case which does not officially support this, due to space reasons.

Feature of upgraded Stratux anti-collision system:

  • ADS-L
  • 1090MHz ES ADS-B, (IN)
  • Mode S, Bearingless, (IN)
  • 868MHz, (I/O)
    • FLARM-compatible radio output, (I/O)
    • Open Glider Network (OGN), (I/O)
    • OGN Drones, (I/O)
    • PilotAware (PAW), (I/O)
    • Flying ad-hoc Networks (FANET), (I/O)
  • Optional: 978MHz ADS-B UAT, (IN)
  • Optional: 161/162MHz Marine AIS, (IN)

I/O = receives (RX) and transmits (TX); IN = receives only.

You already use a Stratux? Upgrade it with additional Sensors!

  • Our developed and optimized circuit boards (PCB) enable proper connection to any additional sensor e.g. ICM-20948 (latest sensor generation), or GY-91 – MPU9250/ MPU9255 for AHRS functionality, or GY-BMP280 for barometric pressure (altitude), since the official Stratux AHRS module is no longer available.
  • Add (OGN) Flarm in/ out to become visible for gliders and be able to see them on your tablet, to avoid collision.


  • Stratux and OpenVario are not an approved or certified aid for flight execution.
  • Therefore, Stratux or OpenVario do not relieve the pilot potential traffic in air space.
