2. What are some benefits of SATCOM? - ANSWER -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.
3. True or False: Signal latency is a minor concern in satellite
communications, so geographic and meteorological factors play an
important role in choosing teleports. - ANSWER FALSE: Signal latency is
, a MAJOR concern in satellite communications, so geographic and
meteorological factors play an important role in choosing teleports.
4. Benefits of WIN-T - ANSWER -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).
5. DOD Gateways - ANSWER -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.
6. Satellite Footprint - ANSWER -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
, 7. What are the three types of coverages? - ANSWER -Earth Coverage
-Area Coverage
-Narrow Coverage
8. Earth Coverage (EC) - ANSWER Uses an EC horn antenna to cover most
of the earth's surface visible from the satellite, normally equal to the
footprint.
9. Area Coverage (AC) - ANSWER 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).
10.Narrow Coverage (NC) - ANSWER Uses spot beam antenna to cover a
confined coverage area containing small earth terminals or small areas
generating large volumes of military communications traffic.
11. Satellite Communications - ANSWER -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
12. Different Types of Satellites - ANSWER -Communications Satellite
14. Geostationary - ANSWER -Synchronized with an area of earth below it
