SATCOM Terminal Characteristics
Used for transmitting and receiving microwave frequencies?
What is a Reflector.
This downlink radio frequency from the assigned satellite is called what?
Receive Freq.
Ground Multiband Terminal can operate is what bands?
C, X, KU, or KA-Bands
About how many active personnel are in the Air Force?
307,000
This receives data from the data terminal equipment, the modem modulates the information into an Intermediate Frequency (IF)
Transmitter
What shape results in a much higher gain than other antennas
What is Parabolic?
Weak downlink signal is sent through what first in order to bring the signal to a usable level?
low noise amplifier (LNA)
In a Dual Hub configuration how man down links can the GMT support?
What is 12.
How many pilots are in the Air Force?
about 13,000
From the modem, the IF is passed to the this device where it is translated into a usable radio frequency
Block Up Converter
This object offers conveying of signals to-and-from the dish, often attached to waveguides.
What is the Feed Horn?
This device is used for frequency translation on the receive side.
Block Down converter
How many 50 foot segments does the PDP support?
5
In what year was the Air Force created as a separate branch of the military?
1947
This device contains vacuum tubes that radio frequencies pass through, as the tube becomes heated it amplifies the signal’s strength
Traveling Wave Tube Amplifier (TWTA)
This stands for modulate-demodulate, and in the case of satellite communications its job is to convert the digital data to usable electromagnetic waves during transmit, and vice versa during receive
What is Modem?
What is the path the receive signal takes.
Feed Horn to LNA to Block down convertor to Receive modem
Dual Hub, Quad-Band Terminal able to operate in C, X, Ku, or Ka Bands
Ground Multiband Terminal
About how much has the F-35 Lightning II fighter program cost so far?
$1.5 trillion
This device provides a variable amount of attenuation to the transmission frequency in order to control total power output
Block Up Convertor
This works by adding an artificial redundancy to a data stream and uses this redundancy to fix errors caused by noise and interference.
What is Forward Error Correction (FEC)
Block Down Converter instead of translating into a radio frequency it instead converts the downlink frequency into what?
Intermediate Frequency (IF).
How many 463L pallets are required to support the GMT?
2
About what percentage of Air Force personnel are female?
20%
Where is the High Powered Amplifier located on the GMT?
On the Antenna
