Mod 9: 1A SATCOM terminal characteristics

The modem then modulates the information, turning the digital baseband into an analog___?

Results in a much higher gain than other antennas, which is useful when we are trying to capture downlink signals

Some rates used today are?

Due to its___the inner conductor is less vulnerable to EMI which is ideal for most environments.

______ are a complex suite of equipment, intended to pass tactical information thousands of miles away.

Used for transmitting/receiving microwave frequencies to and from space.

Feed horn can be adjusted to either horizontal or vertical polarization

Once the information is sent to the modem, it will be in a digital format known as___?

The FEC rate will determine the____to be sent.

Signal will leave the feed horn and strike the dish, focusing it into a concentrated beam. Which reflector process?

What does the satellite modem do?

Typically, modems are designed to use only__access method. However, more modern modems can use__access methods.

Some modems can obfuscate analog data streams which makes it?

This assists with the sub-optimal signal-to-noise level often received at the modem.

Feed horn focuses the outgoing radio frequency into a beam where it is reflected off the parabolic dish.

FEC works by adding an artificial__to a data stream and uses this__to fix errors caused by noise and interference.

What medium can be used to successfully connect to a communications satellite?

What access methods are used to efficiently utilized a satellite’s bandwidth capacity?

SATCOM terminals share common characteristics such as____?

Incoming signal from satellite is reflected off the parabolic dish and gets collected into the feed horn to be relayed

What does the 2nd number indicate?

A____is a horn antenna that offers conveying of signals to-and-from the dish, often attached to waveguides.

_only randomizes data whereas_uses mathematical algorithms to protect information using either a pre-shared key

During transmit operations, the___sends information to the modem to be delivered.

Modernized equipment can utilize Fiber as a means to send RF.

The general purpose of a feed horn is to deliver signals between the___and the____.

Feed horn can be adjusted to either right hand polarized or left hand polarized.

The IF is then sent to the____for final translation to its transmit frequency.

Feed horns are specific to their band.

The__is important when transmitted/received to the Data Terminal Equipment.

Size of the parabolic reflector is___to the frequency used.

Signal will reflect off the parabolic dish into the feed horn where it will be processed further. Reflector process?

Modems can house different connections such as___?

During receive the____signal is sent to the modem and then demodulated to extract the information for the DTE

The word modem stands for___.

The feed horn is also capable of adjusting for different types of___.
