What are some benefits of SATCOM? - ACCURATE ANSWERS✔✔ -
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. - ACCURATE ANSWERS✔✔
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 - ACCURATE ANSWERS✔✔ -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 - ACCURATE ANSWERS✔✔ -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 - ACCURATE ANSWERS✔✔ -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
What are the three types of coverages? - ACCURATE ANSWERS✔✔ -
Earth Coverage
-Area Coverage
-Narrow Coverage
Earth Coverage (EC) - ACCURATE ANSWERS✔✔ 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) - ACCURATE ANSWERS✔✔ 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) - ACCURATE ANSWERS✔✔ 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 - ACCURATE ANSWERS✔✔ -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
