The delay between the transmission and reception of the re-transmitted pulse by the aircraft give the distance. No I could not directly, for 2 reasons :ġ) DME is question/response protocol : The aircraft send a coded pulse and the DME re-transmit it after a short delay. VOR beacons are found between 108 MHz and 117.95 MHz, and it's possible to view the raw signal in SDR#. The beacons are specially designed in such a way that the aircraft can use the beacon to determine a bearing towards the VOR transmitter. VOR stands for VHF Omnidirectional Range and is a way to help aircraft navigate by using fixed ground based beacons. You'll get the most use out of the software if you install it on a portable device like a Raspberry Pi and take it out for a drive as you'll be able to see the VOR angle changing then. In the past we've seen several other posts about RTL-SDRs being used to decode VOR signals, but Thierry's implementation appears to be the easiest way to get a bearing straight away. It is compatible with both RTL-SDR and Airspy radios, and runs on Linux. Vortrack is a simple VOR decoder which calculates the angle towards the VOR. Thank you to Thierry Leconte (TLeconte) for writing in and submitting his new command line based open source software called vortrack.
