+ | By observing their signal, it was found out that the signal received on ground contains clearly distinguishable reflections from flying objects - see e.g. [[http:// | ||

+ | Coordinates and frequencies of all existing VOR beacons can be found at webside [[http:// | ||
+ | |||
+ | |||
+ | ===== Signal processing ===== | ||
+ | |||
+ | VOR beacons work at carrier frequencies in range 108 - 118 HMz. Sampling of this 10 MHz wide band should make it possible to process all beacons at the same time. [[https:// | ||
+ | |||
+ | Using VOR beacons to observe meteors has one advantage - these beacons work in a protected air band that is continuously monitored for interference. Therefore, the quality of obtained data is better than in other bands. | ||

+ | ==== Hardware ==== | ||

+ | To process and digitise signals, a [[http:// | ||

+ | ===== Data from ADS-B ===== | ||
+ | |||
+ | To obtain reference data and to filter airplanes, ADS-B data can be used. | ||

+ | sudo apt-get install librtlsdr-dev git | ||
+ | git clone https:// | ||
+ | cd dump1090 | ||
+ | make | ||
+ | sudo rmmod dvb_usb_rtl28xxu | ||
+ | |||
