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.
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.
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).
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.
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
What are the three types of coverages? - ANSWER--Earth Coverage
,-Area Coverage
-Narrow Coverage
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.
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).
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.
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
Different Types of Satellites - ANSWER--Communications Satellite
Geostationary - ANSWER--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.
Orbits Rotation: Perigee vs Apogee - ANSWER--The point of the orbit closest to Earth is called Perigee
-The point farthest from Earth is known as Apogee
-Perigee is always 180 degrees from Apogee
