Glossary
ADU: Above Deck Unit. The Thuraya Orion IP tracking antenna.
APN: Access Point Name. APNs can be assigned to each external
network interface to allow communications among multiple Internet
Service Providers (ISPs). If use of multiple ISPs is required in your
network, on Thuraya Orion IP wMMI Network Settings screen you can
enable APN and enter the value supplied by your Service Provider.
BDU: Below Deck Unit. The Thuraya Orion IP inside vehicle unit.
DHCP: Dynamic Host Configuration Protocol. DHCP is a communications
protocol that lets network administrators manage centrally and
automate the assignment of IP addresses in an organization's
network. With use of the Internet Protocol, each machine that can
connect to the Internet needs a unique IP address. You must make
sure that the Windows network settings on your PC are set to allow
the network to choose IP settings automatically.
DNS: Domain Name Service, a static, hierarchical name service for
TCP/IP hosts. The network administrator configures the DNS with a list
of host names and IP addresses, allowing users of workstations
configured to query the DNS to specify remote systems by host
names rather than IP addresses. On Thuraya Orion IP wMMI Network
Settings screen, a primary and possibly a secondary DNS address
supplied by your Service Provider must be assigned.
Ethernet: Ethernet is a local area networking method used widely
throughout the computer industry.
GGSN: Gateway GPRS Support Node.
GPRS: General Packet Radio System.
GPS: Global Positioning System. When the GPS receiver in Thuraya Orion
IP gets a bearing on a GPS satellite, the receiver computes and
stores the terminal’s location on earth. That location is used in the
Pointing Process to obtain your location relative to the Thuraya
Satellite.
NAT: Network Address Translation.
Normal Operational Mode: In this mode, the Thuraya Orion IP is
connected to your network, allowing you to perform standard
system activities such as Internet browsing.
PDP: Packet Data Protocol.
