Stratux first time set-up instructions

Use these instructions to learn how to use your Stratux and get it up and running quickly

  • Stratux 3 "Classic Stratux" is developed by an open source community.
  • Stratux 3 "Classic Stratux" receives ADS-B targets,  OGN (Open Glider Network) , PAW (PilotAware), Flying ad-hoc Networks (FANET) and Flarm targets but also sends its own location through (OGN) Flarm or through OGNTP and PAW.
  • The “original” Stratux case does not have a connection for a suction cup holder, but can use either loop cable ties or a velcro strap to mount Stratux on top of the glare shield
  • However, our 2.0 Edition of the Stratux 3 case is optimized and includes mounts for 4 suction cups to attach the Stratux e.g. vertically to a window.
  • Material is 3D printed in PET-G.
  • Stratux has 3 antennas to receive ADS-B and OGN Flarm
    • The long antenna without any description (two rings at the antenna end) must be mounted on the left as it is optimized for Flarm’s 868MHz frequency (European version), US and Canada use the 978MHz antenna on the left.
    • The 2nd long antenna must be mounted on the right to receive ADS-B targets. This antenna has one ring at the end and a 1090MHz printing.
    • The 3rd antenna is the smallest and must be mounted at the bottom, above the safe shutdown switch. It is designed to send Stratux’ own location to other OGN Flarm receivers.
  • Stratux 3 contains a build-in GPS NEO M8N antenna
  • contains AHRS sensor to support artificial horizon
  • It is important that Stratux 3 (T-Beam/ T-Motion) contains a barometric pressure sensor (BMP280), otherwise you will send inaccurate GPS altitude
  • Since Raspberry PI/ Stratux does not contain a shutdown switch out of the box, we modified the device. Pressing the red switch for one second triggers the command to shut down Stratux safely.
  • An additional feature is the pre-installed OpenFlightMap Europe and/or VFR Sectional Charts US to be shown in the Stratux web interface. Those should be used for a quick overview only as maps are not updated on frequently basis.

Stratux 3 Flarm with AHRS + Pressure Sensor + ADS-B + FLARM (OGN) in & out and safe shutdown switch
868MHz/ OGN Flarm -in antenna on the left (has two rings at the end), 1090MHz ADS-B -in antenna on the right (has one ring at the end) - for US and Canada: change left antenna to 978MHz antenna instead.

  • Stratux 2 "Standard Stratux" is developed by an open source community.
  • Stratux 2 "Standard Stratux" receives ADS-B targets, OGN (Open Glider Network) , PAW (PilotAware), Flying ad-hoc Networks (FANET) and Flarm targets.
  • Stratux 2 receives ADS-B and (OGN) Flarm targets
  • contains AHRS sensor to support artificial horizon
  • contains barometric pressure sensor to not rely on inaccurate GPS altitude
  • Stratux will be delivered with 3 antennas, while 2 are in use at same time to receive ADS-B and (OGN) Flarm targets
    • The long antenna without any description (two rings at the antenna end) must be mounted on the left as it is optimized for Flarm’s 868MHz frequency (European version), US and Canada use the 978MHz antenna instead on the left.
    • The 2nd long antenna must be mounted on the right to receive ADS-B targets. This antenna has one ring at the end and a 1090MHz printing
  • contains built-in GPS mouse but an option to connect an additional external GPS mouse.
  • Since Raspberry PI/ Stratux does not contain a shutdown switch out of the box, we modified the device. Pressing the red switch for one second triggers the command to shut down Stratux safely
  • An additional feature is the pre-installed OpenFlightMap Europe and/or VFR Sectional Charts US to be shown in the Stratux web interface. Those should be used for a quick overview only as maps are not updated on frequently basis.

    How to start with Stratux 2?
    How to start with Stratux 2?

  • you can upgrade Stratux 2 by using a standalone OGN Flarm dongle to send your aircraft's position to others

How to use

  • 868/1090MHz antennas should be placed vertically (orthogonal  to the horizon)
  • GPS antenna should have clear view to the sky
  • Connect Stratux to a power bank by using a micro USB-B cable
  • In case Stratux is connected to the electrical system of the aircraft: Stratux should be treated like a radio: first start the engine, then turn on Stratux. To shut down switch off Stratux first, then your aircraft's engine - this helps to avoid voltage peaks.
  • It will boot-up automatically and create a WIFI network, named “stratux”
  • Connect your smartphone/ tablet with this network

Access Stratux Web Interface

  • Open the chrome browser and type the following IP address in the URL bar: http://192.168.10.1 or download the Stratux Manager App for Android.
  • You can set the AHRS sensor orientation under the “settings” tab to e.g. adjust the sensor orientation, to mount Stratux
    • On a window vertically (sideways sensor orientation), or
    • On top of the glare shield (forward sensor orientation)
  • Now open your navigation app such as VFRnav, SkyDeamon or ForeFlight and chose Stratux/ GDL90 protocol to receive data from Stratux
