Recently we found this video from 2013 on YouTube by user carcharias04 showing an RTL-SDR being used for ADS-B on board a 737-800 commercial jet. In the video he uses a custom program that interfaces with RTL1090 and XHSI, which is a navigation display program for the popular flight simulator known as X-Plane.
With his RTL-SDR, RTL1090, his custom software and XHSI running he is able to see a real time display of the primary flight and navigation displays which are the same or similar to the instruments used by the pilots in the cockpit.
Unfortunately, it seems like the uploaders custom interface program is not available anywhere that we know of.
Update 1: The software is this interface available on GitHub. Schumann-resonance from the comments section has uploaded a precompiled binary file here http://www57.zippyshare.com/v/49667810/file.html.
Update 2: To get it to work you need to first set the Table 2 name in RTL1090 to “tableb”, then run RTL1090 first before opening RTL1090-XHSI. Then enter the ICAO of the flight you’d like to use in the text box at the top of the interface window. Now data should begin to appear in the RTL1090-XHSI Window. Now you can open XHSI and it should automatically begin using the ADS-B data.
