Overview

The Ettus Research™ USRP™ (Universal Software Radio Peripheral) is used for a number of military and aerospace applications. In this example, the USRP N200/N210 is used to receive and decode Mode-S beacons from real-world aircraft. The information from these beacons is displayed on Google Earth. This demonstration shows the flexibility offered by GNU Radio, an a open source package and its strong user-base.

The Gnuradio Out-Of-Tree module (OOT) gr-air-modes will be use to receive Mode-S with the USRP.
