The Institute of Atmospheric Physics CAS in Prague is running four ionospheric Doppler
sounders (western Czechia, northern Taiwan, southernmost South Africa and northwestern
Argentina). The key Doppler sounder in western Czechia consists from three measuring paths
with a central receiver in Prague and utilizes simultaneously three different frequencies, i.e.
different reflection heights to get quasi-3-D pattern.
The TID detection method has been developed and we obtained various statistical results on
behavior of gravity waves. Then, method of automatic TID detection to allow 24/7 monitoring
was developed and tested. Automatic detection of TIDs allows to give real-time alarms and/or
analyze origin of some problems in GNSS signals. The product is distributed via internet to a
data center or directly to users.
We will demonstrate automatic detection and monitoring of TIDs based on ionospheric
Doppler sounding, particularly shorter-period TIDs.
