Army (DODIN-A)
INC 1
→ Networking at the halt
INC 2
→ Networking on the move
What are some benefits of SATCOM?
→ -SATCOM allows for service over the Polar Regions, the oceans, and the remote areas
of the world.
→
→ -SATCOM provides global connectivity to widely dispersed small and mobile forces.
→
→ -SATCOM acts as a network extension and provides long-haul communications to areas
where terrestrial architecture may be insufficient or where line of sight equipment is
inadequate.
True or False: Signal latency is a minor concern in satellite communications, so geographic and
meteorological factors play an important role in choosing teleports.
→ FALSE: Signal latency is a MAJOR concern in satellite communications, so geographic
and meteorological factors play an important role in choosing teleports.
Benefits of WIN-T
→ -On-demand, pre-positioned links to DISN services.
→
→ -Automatic routing and information transfer over the most effective SATCOM network.
→
→ -The Wideband Global SATCOM (WGS) allows for cross-banding for communications
between dissimilar SATCOM systems and frequency bands(C band, X band, Ku band,
and Ka band).
DOD Gateways
→ -Gateways give tactical terminals access to DISN services regardless of their
deployment location.
→
→ -DOD gateways are located across the globe to offer gateway entry points close to
warfighters in all theaters.
→
→ -DOD gateways provide long-haul network transport and connections from the
deployed tactical network to the strategic infrastructure.
Satellite Footprint
→ -The area of the earth's surface covered by the satellite antenna's beam pattern within
the field of view of the satellite's transmitters or sensors.
→
→ -Satellite transmissions can cover 1/3 of the earth's surface
→ Uses an EC horn antenna to cover most of the earth's surface visible from the satellite,
normally equal to the footprint.
Area Coverage (AC)
→ Uses a steerable dish or multi-beam antenna to cover areas of concentrated users that
often deploy small, mobile or transportable earth terminals (I.e. ships, aircraft, and
ground tactical terminals).
Narrow Coverage (NC)
→ Uses spot beam antenna to cover a confined coverage area containing small earth
terminals or small areas generating large volumes of military communications traffic.
Satellite Communications
→ -Satellite transmissions can cover 1/3 of the earth's surface
→
→ -Each satellite is equipped with various "transponders" consisting of a transceiver and
an antenna tuned to a certain part of the allocated spectrum
→
→ -The incoming signal is amplified and then rebroadcast on a different frequency
→
→ -One channel dedicated to transmitting and one channel for receiving
→ -Synchronized with an area of earth below it
→
→ -Centered on the equator
→
→ -Approximately 35,786 km above the earth's surface
→
→ -Orbit period = 1 day.
