Stratux

Hello! Stratux is a homebuilt ADS-B In receiver for pilots. It's easy to assemble from inexpensive, off-the-shelf hardware, and probably already works with your electronic flight bag (EFB) of choice. Even better, if you're so inclined, the software is open-source and hackable so you can build the system that's right for you.

To get started, order the parts from the shopping list below, plug everything in, and load up the software.

  3. If using Windows, follow instructions for Win32DiskImager.
  4. If using Mac, download and follow prompts for Pi Filler.

Assembly

  1. Stick heat sinks onto Raspberry Pi components and snap together case as specified in the Vilros information booklet.
  2. Insert radio (RTL-SDR) dongle into a USB port.
  3. Insert (and secure) the Micro SD card.
  4. Power up and connect to the "stratux" WiFi network.
