What's MIOS?

 

The Meteor and ionospheric Irregularity Observation System (MIOS) consists of two parts, powerful radar and sensitive optical subsystems which are for observing meteor trail irregularity and its corresponding optical meteor, respectively. By using the optical multi-station video cameras, and radar spaced antenna array, MIOS has the capability to determine the positions of optical meteor and meteor irregularity, and derive the meteoroid parameters. One major goal of the MIOS is to study how the entry of meteoroids changes the Earth’s ionosphere through combining measurements of optical meteor with radar specular and non-specular meteor echoes and ionospheric irregularity echoes.
