The Next Level of our Navigation Computers

Gone are the days when gliders were navigated using paper maps. With the SteFly OpenVario, cockpits all over the world could be equipped with a modern gliding computer with a large, colored moving map. Many young athletes grew up with the OpenVario. Because thanks to the open source idea and the great global sales success, an upgrade for all gliders became affordable. True to the motto: good avionics should not cost more than the airplane!

But the state of the art continues to advance. Displays are becoming brighter and more energy efficient, processors are becoming more powerful and with Android an operating system is available that is compatible with open source software such as XCSoar or OpenSoar as well as with popular apps such as SkyDemon or SeeYou Navigator.

In short, it's time for something new: more powerful, more intuitive and even better connectivity

Easy replacement of a SteFly OpenVario

Of course, we will continue to help with spare parts and repairs for the SteFly OpenVario. SteFly and the OpenVario are inseparably linked. The OpenVario was the cornerstone of our gliding activities. And we also know and appreciate the motto:

Never touch a running system!

However, with the new SteFly Nav 5.7 and 7.0 devices we want to make the exchange as uncomplicated as possible. The motto is more fun in the cockpit and not spending more time in the workshop.

  • The panel cutout and the four mounting holes are identical to those of the corresponding 7´´/ 5.7´´OpenVario
  • Both height and width of the SteFly NAV 5.7 are identical to OpenVario 5.7
  • The width of the SteFly NAV 7.0 is 7.8 mm less than that of the OpenVario, the height is identical
  • The housing depth is significantly more compact than for the OpenVario: only a maximum of 36 mm instead of 80 mm for the OpenVario!
  • Same D-Sub connector (power supply and external speaker) as the OpenVario, so plug and play! 
  • The SteFly Rotary module and the stick remote control can easily be plugged into the USB ports and are the ideal addition to the touchscreen

If an OpenVario fits, then a corresponding SteFly NAV 5.7 or 7.0 will also fit!

The following should be noted when switching from OpenVario:

  • SteFly Nav no longer has the option of integrating a sensor board into the housing. Instead, our much more precise E-Vario LARUS can be connected to the new navigation computer via RJ45, Bluetooth or WiFi. LARUS, based on GNSS and acceleration sensors, measures vertical air movements significantly faster and more precisely than total energy variometers with a TEK nozzle. In addition, the horizontal wind is calculated accurately at all times without having to fly circles. And an AHRS (for the artificial horizon) is also on board.
  • The temperature sensor of the OpenVario sensor board cannot be connected to the SteFly Nav device. We are developing a new temperature sensor.

SteFly Nav and LARUS – the perfect team!
