Block 5.2

Which frequency band's disadvantage is that it is greatly affected by radio shadow and disrupted by vegetation?

Which frequency band's advantage is not being affected by vegetation?

Which of these is NOT needed to establish a TADIL-A link?

What is the frequency range of the VHF band?

How many frequency bands make up the RF spectrum

Occurs when you focus on a limited number of environmental cues, excluding others with a higher/more immediate priority

TDL used exclusively by JSTARS and the Army

In Link 16, this acts as the single time source for time synchronization of all units entering the network

A group of artificial satellites working in concert

A function of the ICS which allows users the ability to continuously transmit without having to depress the push-to-talk

What are two contributing factors for satellite acquisition?

Who governs the RF spectrum

This TDL allows for jam-free communications via the internet.

Which frequency band's disadvantage is the amount of power required to produce a usable signal at the receiving station?

The result of the gradual dispersion of the RF energy as it travels through space

Designed to exchange digital data over a common network that is continuously and automatically updated

Communication which requires safeguarding.

SATCOM loss that tends to interfere with the signal causing distortion of the intelligence or suppression of the signal

What is the satellite period of a sub-synchronous satellite?

What is the primary purpose of the VHF band?

Which is NOT a reason to use voice tell?

SATCOM loss which depends primarily on equipment design

This is defined as the reporting of information through the use of a specified format.

A circular orbit in which a satellite is stationed in the Earth's equitorial plane at a height of 22,300 statute miles

Identification function of Link 16 which eliminate the need for voice status updates

A lat/long position for all Link 11 PUs to use as a base position to report their position/tracks to the other units

The extreme opposite of Situational Awareness

The ability to know what is going on around you - in the past, present, and in anticipation of the future

Secure-capable TDL that employs a half-duplex, networked comm technique/standard message formats.

What voice tell format is a set of character-oriented message text formats used ISO C2 systems for the exchange of info?

What is the frequency range of the UHF band?

What is the channel spacing of the HF band?

Satellite system reserved for communications between Navy and AF ships, submarines, aircraft, and ground units

What is the primary purpose of the UHF band?

What voice tell format produces messages that are both machine processed and human readable?

How many satellites are in the UFO constellation?

A near real-time, multi-participant means of textually communicating among military units.

How many days can UFO satellites operate autonomously?

Satellite system that provides secure, jam-resistant comm to meet essential wartime requirements for high priority users

Which frequency band's advantage is effective use of the frequency spectrum?

In Link 16, this assigns a proportional number of time slots to each JTIDS Unit

The internal communication system is encrypted for the passing of classified communications.

This refers to the coordinates to which the Earth station antenna must be pointed to communicate with the satellite

What is the frequency range of the HF band?

A high-capacity info distribution system that provides secure, flexible, extended LOS/jam-resistant infor exchange

Communication which relies solely on the transmission and reception of radio waves to pass information.

Which voice tell format breaks information down into base elements of who, what, where, and when?

This takes place within your airframe with other areas of the crew to work together towards a desired goal.

The passing of information from one functional area to another for the purpose of building situational awareness

How many channels does the UFO constellation provide?

What voice tell format offers a simple option to quickly report a target by referencing landmarks or specific locations?

A Link 11 PU used to control the orderly flow of information between PUs

The total area of the Earth seen by the satellite at any given instant

A small section of the RF spectrum in which channels are used for the same purpose

What voice tell format facilitates exchange of info between US & allied commands and reduces/eliminates dual reporting?

Which voice tell format is used to pass target informtion for a close air support mission?

This is measured eastward from geographic north to the projection of the satellite path on the local horizontal plane

Provides users with clear/secure voice/data communications over great distances while avoiding the limitations of HF

Which frequency(ies) is(are) used for TADIL-A operations?

What is the primary purpose of the HF band?

Provides intra-aircraft communications and coordination

What voice tell format provides uniform reporting procedures to be used in all defense conditions?

SATCOM loss due to the angular misalignment between transmitter and receiver antenna.

This is measured upward from the local horizontal plane at the Earth station to the satellite path

A system that relays radio transmission between terminals.

A satellite orbit in which a satellite altitude is less than 22,300 statute miles

Satellite constellations that operate at UHF, SHF, and EHF frequencies
