The
General Administration of Civil Aviation of China (CAAC) has awarded
VSAT terminal provider PolarSat with multiple orders for supplying
additional VSATPlus II satellite communications equipment and
attached services.
The
CAAC will use the new batch of PolarSat VSAT equipment to expand its
communications network to more than 350 sites that cover the entire
54MHz transponder.
The
VSATPlus II network will create a full mesh network that links
the headquarters offices and regional centers of the Air Traffic
Management Bureau (ATMB.) All sites will support a complex mix of
voice and data communications. For normal telephony traffic and
hotline applications, such as VHF voice for Air Traffic Controllers,
the network provides a mix of pre-assigned (PAMA) and on-demand
(DAMA) voice circuits.
Furthermore,
the PolarSat VSAT mesh network will provide data communications for
radar multicasting, LAN-to-LAN connectivity, client-server
applications, general corporate communications, and other
applications. It will also provide backup connectivity to the ATMB’s
terrestrial network.
