Romantis UHP TDMA Characterization and Geolocation

January 1, 2024

The Kratos Global Sensor Network discovered and characterized a Romantis UHP Network operating on Express AM8. By decoding the network burst time plan, Kratos was able to uniquely identify each modem on the network and geolocate each terminal. The hub operates from an unacknowledged facility south of Moscow while edge modems are located in Russian embassies across Europe.

The Podolsk/Romantsevo Communications Complex south of Moscow is the hub for 7 TDMA networks with the following remote sites: Yerevan, Brussels, Vienna, Lisbon, Bonn, Berlin, Warsaw, Sofia, Madrid, Helsinki, Prague, Tirana, Paris, Budapest. In each case, overhead imagery shows an antenna pointed towards Express AM-8.
