What is SSIXS?
|
Submarine Satellite Information Exchange
Subsystem |
|
This is a narrowband
uhf subsystem that links voice communications between ships and connects with wide-area shore voice networks. |
Secure Voice Subsystem
|
|
This subsystem is specifically designed for
special intelligence communications |
Tactical Intelligence Subsystem (TACINTEL).
|
|
This is a one-way broadcast of
tactical information from command centers ashore to afloat units primarily in support of over-the-horizon targeting (OTH-T). |
Tactical Data Information Exchange Subsystem (TADIXS)
|
|
This subsystem continues to provide inter-and intrabattle
group communications and is now also designated as the return path for ship-to-shore OTH-T communications. |
Officer in Tactical Command Information Exchange Subsystem (OTCIXS).
|
|
This subsystem was designed to
multiplex several subsystems, or users, on one satellite channel, allowing more satellite circuits to use a single uhf satellite channel. |
Demand Assigned Multiple Access (DAMA)
|
|
Four Naval Computer and Telecommunications Area Master
Stations (NCTAMS) have primary responsibility for naval communications via satellite. They are: |
NCTAMS LANT, Norfolk, Virginia
NCTAMS MED, Naples, Italy NCTAMS WESTPAC, Finegayan, Guam NCTAMS EASTPAC, Wahiawa, Hawaii |
|
provides connectivity between NCTAMS EASTPAC and NCTAMS LANT?
|
Naval Computer and Telecommunications
Station (NCTS), San Diego, California |
|
What is the purpose of baseband equipment?
|
used to collect and
control the transmitted or received communications. |
|
What is the purpose of the rf terminal?
|
used by the baseband system to
transmit and receive via satellite link. |
|
Fleet Satellite Broadcast Subsystem
provides the capability to transmit Fleet Broadcast message traffic in a high-level jamming environment. The subsystem has how many subchannels of encrypted message traffic at an input data rate of what bps per channel? |
15 sub channels
75 bps |
|
The shore terminal transmits this data on a direct-sequence, spreadspectrum
what signal to the satellite, where the signal is translated to what and down-linked to the subscriber. |
SHF
UHF |
|
The Fleet Satellite Broadcast message traffic is queued and/or channel selected by two processor controlled message switching systems before transmission. These systems are?
|
Naval Communications
Processing and Routing System (NAVCOMPARS) , and STREAMLINER |
|
For general service message
traffic. |
NAVCOMPARS
|
|
For special intelligence
message traffic. |
STREAMLINER
