Aerobits is a Polish technology company that has been operating on a global market since 2017. We deal with miniaturization of avionic systems, such as aviation transponders. All solutions are based on a patented technology that allows to process radio signals on very small surfaces. This concept is at the core of our OEM modules (low-level assembly function modules), which are the basic building block of miniaturized avionics.The beginnings of Aerobits date back to 2015, when a subminiature ADS-B implementation (Automatic Dependant Surveillance-Broadcast) was created at the West Pomeranian University of Technology in Szczecin in conjunction with the multi- GNSS function. The OEM module with an area of only <4cm2 and weighing 1.5g, to this day is the smallest ADS-B / GNSS fusion in the world.
