Radio Meteor Hunting

On this channel, you can watch and listen to the radio echoes of meteors recorded in Kraków by an antenna and receiver tuned to 143.050 MHz — the signal from the GRAVES radar.  It is located near Dijon in France, approximately 1,100 km from Kraków. The radar transmits continuously 24 hours a day, and its signal is reflected off the ionised trails left by meteors entering the atmosphere and reaches the antenna. In the signal visualisation and audio, you can observe echoes from meteors (very close to frequency 143.050 MHz) and also satellites (characteristic longer signals with a slow  frequency drift), and occasionally from aircrafts. Each short ‘ping’ is likely a meteor. Detection and counting meteors are carried out using SDRuno and RadioMeteorSniffer (RMS) software.

Due to the rapidly increasing number of satellites, we have a unique opportunity to still observe radio meteors; in the future, signals from satellites may completely dominate the radio sky.
