What is a TRC 170?

The AN/TRC-170(V)2 is a digital tropospheric scatter radio terminal which provides connectivity between two major nodes. The AN/TRC-170(V)2 can operate in either dual space or quad frequency diversity. The radio can be configured in either Line-of-Sight (LOS) or tropospheric scatter modes of propagation.

What is troposcatter system?

Troposcatter (short for tropospheric scatter) technology uses particles that make up the Earth’s atmosphere as a reflector for microwave radio signals. As they pass through the troposphere, some of the energy is scattered back toward the Earth, allowing the receiver station to pick up the signal.

At what frequency Troposcatter propagation will occur?

Explanation: Tropospheric scattering occurs at a frequency above 30MHz. So, this occurs in space wave propagation. Signal scatters in forward direction above the radio horizon and it travels beyond the LOS. Ground wave propagation occurs at less the 2MHz and sky wave at 2 to 30 MHz frequency.

What is Tropo communication?

Tropospheric scatter, also known as troposcatter, is a method of communicating with microwave radio signals over considerable distances – often up to 300 kilometres (190 mi), and further depending on terrain and climate factors. Troposcatter allows microwave communication beyond the horizon.

What is TRC school?

What is TRC? Text Reading and Comprehension. TRC is an individually administered assessment that uses leveled readers from a book set to determine a student’s instructional reading level — the reading level at which he or she not only performs well, but is challenged.

What does TTC mean?

(TTC stands for trying-to-conceive.)

What is duct propagation?

Duct propagation is the phenomenon of transmitting UHF and VHF signals to longer distances. Basically, the wave propagates inside a duct by undergoing successive refractions inside it. The change in the refractive index due to warm and cool layers in the atmosphere causes duct propagation.

What is skip distance in radio communication?

A skip distance is the distance a radio wave travels, usually including a hop in the ionosphere. A skip distance is a distance on the Earth’s surface between the two points where radio waves from a transmitter, refracted downwards by different layers of the ionosphere, fall.

What is meant by critical frequency?

Critical frequency is the highest magnitude of frequency above which the waves penetrate the ionosphere and below which the waves are reflected back from the ionosphere. It is denoted by “fc”. Its value is not fixed and it depends upon the electron density of the ionosphere.

What causes tropospheric ducting of radio waves?

What causes tropospheric ducting? This is where a layer of air in the troposphere will be at a higher temperature than the layer below it. Some of the radio signals from a transmitter bounce back towards the ground and potentially up again. The inversion effectively creates a duct for signals to travel along.

What does the troposphere do?

The water cycle also occurs in this layer of the atmosphere. The water cycle helps form clouds, which in form can help produce rain, sleet, snow and freezing rain. As you see, the troposphere is an important layer in Earth’s Atmosphere, as it is the layer that we live in and the layer that gives us weather.

How big is the range of AN TRC-170?

• The AN/TRC-170(V)3 may also communicate using Line-of-Sight (LOS) microwave communication. Using the LOS method and equipment, the range is about 35 miles. • It is important to understand that the s ignal loss caused by scattering and diffraction are large compared to the loss incurred in Direct Line of Sight microwave communication.

Where did the Marine Corps get the troposcatter radio?

QUANTICO MARINE BASE, Va. – U.S. Marine Corps communications experts needed a next-generation troposcatter radio to replace the service’s AN/TRC-170 tropospheric scatter microwave radio terminal. They found their solution from Cubic GATR Technologies Inc. in Huntsville, Ala.

Who are the operators of the Marine TRC-170?

George and Hardin are both AN/TRC-170 operators assigned to Marine Wing Communications Squadron 28, Marine Air Control Group 28, 2nd Marine Aircraft Wing. Some equipment in the Marine Corps is so valued that it has been around for generations and still operating at top capacity. One such piece of gear is the AN/TRC-170.

How is a tropospheric scatter communications system deployed?

The system is deployed on a KAMAZ-4310 truck, using a towed 2х8-Т400-1ВПС electrical generator.
