Communications<br />

Internal communication systems are distributed between the assembly<br />

and command ship and launch platform. This system includes CCTVs,<br />

telephones, intercom, public address, video teleconferencing, and vesselto-vessel<br />

communications (also known as the line-of-sight [LOS]<br />

system).<br />

This system links with the external communication system that provides<br />

a worldwide network that interconnects the various segments of the <strong>Sea</strong><br />

<strong>Launch</strong> program (see fig. 10-1). The external communication system includes<br />

INTELSAT and two ground stations. The ground stations are located<br />

in Brewster, Washington, and Eik, Norway, and provide the primary<br />

distribution gateways to the other communication nodes. Customers<br />

can connect to the <strong>Sea</strong> <strong>Launch</strong> communication network through the convenient<br />

Brewster site. The INTELSAT system ties in with the ACS and<br />

launch platform PABX systems to provide telephone connectivity. Additionally,<br />

critical telephone capability can be ensured by INMARSAT (see<br />

fig. 9-13).<br />
