How Do Satellites Communicate With Objects On Earth?

A satellite communicates with objects on Earth by sending and receiving signals. Signals are sent in the form of radio waves, and the distance between the satellite and the object is determined by the wavelength of the signal. The signal is then received by the object, and the object can be identified by the characteristics of the signal.

A satellite travels at about the speed of light.

What happens in a receiver aerial when radio waves are absorbed by it?

Radio waves are absorbed by a receiver aerial when they are in the range of the antenna. This causes the radio waves to be reflected back and amplified.

What type of device communicates with satellites?

A satellite is a small, electronic satellite that orbits Earth and communicates with other satellites.

Why do mobile phones use microwaves instead of radio waves?

Mobile phones use microwaves to communicate with each other because they are more efficient than radio waves. Radio waves can travel a long way and can be heard by far, but microwaves can only travel a few inches. This makes them more efficient for communicating with other people and objects.

Which is the communication device?

A phone

How are satellites controlled from Earth?

Satellites are controlled from Earth by satellites that send and receive signals. These signals are used to control the satellites.

Which type of communication is satellite communication?

Satellite communication is a type of communication that uses satellites to send and receive messages.

What are the 3 types of satellite communication?

A satellite communication is a type of communication that uses satellites to send and receive messages. These messages can be either electronic or electronic-based.

How is satellite communication used in wireless communication?

A satellite communication system uses satellites to relay information between two points. This type of communication is often used in wireless communication because it is more reliable than traditional telephone communication.

Are infrared microwave and radio waves harmful?

Yes, infrared microwave and radio waves are harmful. They can cause cancer, heart disease, and other health problems.

Do satellites crash into each other?

There is no definitive answer to this question as it is a matter of opinion. Some people believe that satellites can collide, while others believe that they do not. It is also possible that there are no significant collisions between satellites, but that is also difficult to confirm.

Do satellites use VHF?

No, satellites use UHF frequencies.

What frequencies are harmful to humans?

There is no one answer to this question as it depends on the individual and the environment in which they live. However, some harmful frequencies that can be harmful to humans include radiofrequency radiation, microwaves, and cellphone towers.

Why are microwaves suitable for satellites?

Microwaves are very efficient at transferring energy and can be used to power satellites.

How do waves transmit information?

Waves can transmit information by bending and reflecting off of other objects.

What are the elements of satellite communication?

The elements of satellite communication are:-A satellite-A transmitter-A receiver

How does satellite communication and terrestrial communication differ?

Satellite communication is a type of communication that uses satellites to send and receive messages. Terrestrial communication is a type of communication that uses the Earth’s atmosphere to send and receive messages.

What EM waves are used in texting?

EM waves are used in texting because they are short-wavelength and can travel through a phone’s screen quickly.

How are microwaves used in radar?

Microwaves are used in radar to send signals that are used to track objects.

Do satellites use radio waves or microwaves?

Satellites use both radio waves and microwaves to communicate with other satellites and ground stations.

Where is the satellite communication taking place in our atmosphere?

The satellite communication is taking place in the atmosphere because satellites are used to communicate with each other.

What is a satellite carrier?

A satellite carrier is a company that provides telecommunications services to satellites.

Why can’t radio waves communicate with satellites?

Radio waves are unable to travel through the Earth’s surface, which is why they can’t communicate with satellites.

How many communication satellites are there?

There are currently about 30 communication satellites in orbit.

How are satellites powered?

Satellites are powered by electric fields that are created by the Earth’s magnetic field.

How do satellites send images back to Earth?

A satellite sends back images of the Earth using a set of antennas that send and receive signals. The images are sent back and forth between the satellite and ground stations, which then analyze the images to create a map of the Earth.

How do we use satellites for communication?

Satellites can be used for communication by broadcasting a signal from the satellite to a receiver on Earth.

How do satellites receive signals?

A satellite Receives signals from the Earth by reflecting off of the Earth’s surface. The signals are then amplified and sent back to the satellite.
