The Mozambique ATC network consists of total of 11 sites with two Air Traffic Control (ATC) regional control centres all connected in a full mesh all-IP based network. The VSAT network provides backbone connectivity for VHF voice communications relay to cover the whole continental airspace and Oceanic airspace delegated to the Beira Flight Information Region. 

Mozambican airspace is divided into northern and southern regions that are controlled by their ATC control centres, located in Maputo and Beira. The VSATPlus3 provides geographic redundancy in transporting control centre traffic. In the event of a failure of one of the centres the VSATPlus3 system automatically provides connectivity to the other ATC centre. 

All sites will support a complex mix of voice and data communications including hot lines, AFTN, AMHS, ADS B, Internet and general corporate internal communications.
