What Can Be Used To Communicate With Satellites?

Radio waves

How does a satellite communication work?

Satellites communicate by using radio waves to send signals to the antennas on the Earth. The antennas then capture those signals and process the information coming from those signals.

How did satellites improve communication?

Answer: The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated geographical points.

Why is communication satellite important to the society?

The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated geographical points. Communications satellites use a wide range of radio and microwave frequencies.

What is the bandwidth of satellite communication?

Internet distribution via satellites, particularly GEO satellites, has the following merits: High bandwidth. A Ka-band (20-30 GHz) satellite can deliver throughput at gigabits per second rates.

What frequency bands are used in satellite communication?

The major frequency bands used for satellite communication in India are S-band, C-band, Upper Extended C band, Ku band and Ka band. The INSAT/GSAT satellites carry transponders in these bands.

Why can't radio waves communicate with satellites?

There is less noise with digital signals. > The ionosphere reflects radio waves with frequencies below 30 MHz (30 million hertz), so higher frequencies are needed for satellite communication.

Is space wave used for satellite communication?

Space waves are used for line of sight communication as well as satellite communication.

Why do satellites use high frequencies?

What does change at higher frequencies is the antenna beam width, it becomes narrower. Thus, in crowded synchronous orbit, you can space the satellites closer together. You also can get wider bandwidths at higher frequencies.

Which wave is used in satellite communication?

Radio waves

Why are VHF HF and microwave signal used in satellite communication?

Why are VHF, UHF, and microwave signals used in satellite communication? Explanation: VHF, UHF, and microwave signals penetrate the ionosphere with little or no attenuation and are not refracted to earth. Lower frequencies undergo total internal refraction and get reflected back to earth.

What can be used to communicate with satellites?

Radio waves

What are look angles?

The following two angles of earth station antenna combined together are called as look angles. Azimuth Angle. Elevation Angle.

What EM wave is used to detect fake bills?

Ultraviolet waves

What is water scientific name?


What fields can computer science be applied to?

What are asynchronous motors used for?

These motors are frequently used in 90% of the applications all over the world due to reasons like great robustness and reliability. These motors are used in different moving or rotating machines like lifts, fans, grinders, etc.

Why is cuboid not a regular polyhedron?

Answer : Option (a) cuboid is not a regular polyhedron because its vertices are not formed by the same number of faces.

What is a good KPI?

Good KPIs: Provide objective evidence of progress towards achieving a desired result. Measure what is intended to be measured to help inform better decision making. Offer a comparison that gauges the degree of performance change over time.

How do you keep in shape?

6 Inexpensive Ways to Stay in Shape

  1. Walking. Walking for 30 minutes a day can help you lose weight, control your blood sugar, and lower your cholesterol and blood pressure, and reduce stress.
  2. Suspension trainer (TRX)
  3. Exercise balls.
  4. Dumbbells or kettlebells.
  5. Calisthenics.
  6. Online exercise videos.

What is vehicle traction?

While friction is a general physical expression, vehicle traction can be defined as the friction between a drive wheel and the road surface. “traction is the friction between a drive wheel and the road surface. If you lose traction, you lose road grip.”
