Back in 2017, we first posted about using a program called RTL1090-XHSI which is used to display a simulated aircraft cockpit using live data acquired directly from an RTL-SDR receiving ADS-B flight data from nearby aircraft. The ADS-B signal provides not only position and heading data but also information about altitude and speed, which is then used to simulate the cockpit display.
Recently Al wrote in and wanted to share with us a step-by-step tutorial that he has created that shows how to set this up. The guide shows how to download, install and use all the software programs required.
