Requirements for SATCOM service worldwide significantly exceed the capacity of current MILSATCOM systems.
TRUE
Satellite communications are often the only means of providing critical beyond line of sight communications.
TRUE
Wideband satellite communications support ______________.
ALL THE ANSWERS ARE CORRECT
It is impossible for a unit to lose their primary communication link with the military strategic and tactical relay system (MILSTAR) satellite network.
FALSE
Since most communications satellites are in geosynchronous orbit, the region of the world which receives least coverage is the ______________ region.
POLAR
MILSTAR stands for
MILITARY STRATEGIC AND TACTICAL RELAY SYSTEM SATELLITE NETWORK
Protected satellite communications permits the use of smaller antennas that increase its mobility, enabling wider use of submarine, airborne, and other mobile terminals
TRUE
Satellite Communications:
COLLECTIVELY PROVIDE AN ESSENTIAL ELEMENT OF NATIONAL AND DEPARTNMENT OF DEFENSE (DOD) COMMUNICATIONS WORLDWIDE.
PERMIT INFORMATION TO TRANSFER FROM THE HIGHEST LEVELS OF GOVERNMENT TO THE THEATER TACTICAL LEVEL FOR ALL MATTERS TO INCLUDE OPERATIONS, LOGISTICS, INTELLIGENCE, PERSONNEL, AND DIPLOMACYL
The communication bands in which the military operates satellite communication systems are
UHF, SHF, EHF, COMMERCIAL
Heavy solar activity ______________.
CAN DISRUPT SATELLITE COMMUNICATIONS FOR SHORT PERIODS OF TIME, CAUSING COMMUNICATIONS OUTAGES IN EXTREME CASES
Narrowband Satellite Communications supports ______________ data rates for both mobile and fixed users by providing access on a single dedicated channel or on a demand assigned multiple access channels.SECURE VOICE AND DATA TRANSMISSION AT RELATIVELY LOWAll radio receivers, including satellite systems, are susceptible to jamming and interference.TRUESatellite communications provide ______________ coverage enabling military leaders to maintain ______________ and convey their intent to the operational commander.NEAR-GLOCAL / STRATEGIC SITUATIONAL AWARENESSSATCOM in the Ku- and Ka- bands, as well as EHF systems, are particularly affected by rain (the higher the frequency, the greater the effect).
