Tropospheric communication systems

Purpose of tropospheric communication systems:

Providing over-the-horizon communication capabilities for telecommunication networks used in various applications with transmission speeds of up to 50 Mbps.

system type station type antenna diameter, m transmitter power, W communication range per hop, km
lightweight station mobile 1.25 200 up to 120 km
medium-sized station mobile 2.0 500 140–180 km
heavyweight station stationary / transportable 2.5 2,000 160–200 km
hub-type (multidirectional station) transportable 2.0 1,000 up to 160 km

All the stations operate in the frequency range of 4,400–5,000 MHz using standard communication network protocols and support traffic routing.
This product line is currently under development.


  • High-speed (up to 50 Mbps) modem
  • 2 antennas
  • 2 transceivers
  • Power supply unit
  • Station control system
  • General-purpose and specialized communication networks. Certain special applications, including those addressing military and general economic demands, call for means of tropospheric communications to ensure the delivery of information in hard-to-reach and sparsely-populated regions, in highlands, or other areas interspersed with obstacles or separated by water spaces, e. g. to establish communications between islands, to connect an offshore gas and oil platform with the coastline facilities, to set up engineering communications along rivers and highways, or to deliver information from remote weather stations.
  • Compact transportable tropospheric communication systems are a vital asset for emergency response operations, geological fieldwork, environmental monitoring, and traffic artery upgrades.
  • It makes sense to use tropospheric communications capable of providing stable transmission of data and technical information over long distances for interlinking radar installations serving general economic or military purposes and comprising an integrated air traffic control system (ATC) as well as for addressing navigation safety issues in coastal areas.
