C.2.2 Direct Internet Connection
The Iridium Direct Internet service allows users to connect to the Internet via the Iridium
gateway without having to sign up with an Internet service provider. This service utilizes a
dedicated Apollo Server at the Iridium gateway, which provides high-speed connectivity to
the Internet and optimizes server-to-Iridium modem communications. The dial-up networking
setup is similar to the dial-up networking setup for a landline telephone. The only difference
is that the dialed telephone number is an international number provided by Iridium. Figure
C3 illustrates how Iridium Internet (NIPRNet) call is routed.

Direct Internet service can be enhanced using Windows-based emulated point-to-point
protocol (PPP) called the Apollo Emulator. With the use of the Apollo Emulator software instead
of Microsoft Windows® dial-up networking, Direct Internet service can reduce connection time
