Most communication Satellites orbit in what is know as a geosynchronous orbit. Meaning that they move at the same speed as the Earth making them appear to be non moving. These orbits are at the altitude of 22,450 miles above the Earth. Very few satellites orbit as close as a few hundred kilometers of the Earth because the force of gravity would cause them to slow down and eventually fall from the orbit back to Earth. The application of Propagation would be determining how a radio signal will react and how it would effect it's characteristics over certain terrain like mountains for example.
What else can I help you with?
What should be the position of the antenna with respect to the direction of the transmitted radio waves so that the properly tuned in radio gives the better reception?
The antenna should be parallel to the electrostatic field of the wave, and perpendicular to its magnetic field and to its direction of propagation.
What wave viabrates faster radio wave or microwaves?
Microwaves ARE radio waves, with frequencies above 3 GHz.
Is ultrasonic wave radio frequency?
ultrasonic wave is sound frequency
What is a radio wave?
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
Is the speed of a radio wave in a vacuum greater than the speed of a gamma ray?
No. The speed of all electromagnetic radiation is the same in vacuum, from the longest radio wave to the shortest gamma wave.
What is the different modes of the radio wave propagation?
Ground wave, sky wave and space wave propagation

What has the author K G Budden written?

Is a radio wave longitudinal?
No, radio waves are transverse waves, meaning the oscillation of the wave is perpendicular to the direction of wave propagation. Longitudinal waves have oscillations parallel to the direction of wave motion.
What is the space wave propagation frequency?
Space wave propagation frequency is nothing special, it is the same frequency of the wave in question, for example WLAN Wifi produces 5.2 GHz radio wave from your computer or from router, so that would be the the space wave propagation frequency in question

What are the applications of sky wave propagation?
Sky wave propagation is used in long-distance radio communications. It is commonly used for broadcasting, military communications, and amateur radio operations. Sky wave propagation allows signals to be transmitted over long distances without the need for expensive infrastructure.
What has the author Lucien Boithias written?
Lucien Boithias has written: 'Radiowave Propagation' -- subject(s): Tropospheric radio wave propagation
What is meant by ground wave propagation?
Ground wave propagation refers to the transmission of radio waves along the surface of the Earth. This type of propagation is commonly utilized for medium and long-distance communication, particularly in the AM radio band. Ground wave signals can follow the curvature of the Earth, allowing for extended coverage compared to line-of-sight transmission.
Is radio wave longitude or transverse?
A radio wave is an electromagnetic wave. Electromagnetic waves are transverse waves.
how does layer of ionosphere affects in the propagation of radio waves?
The ionosphere layer affects radio wave propagation by reflecting or refracting the waves back to Earth. Different layers of the ionosphere interact with radio waves of different frequencies, allowing for long-distance communication via multiple hops. Changes in the ionosphere's density and ionization levels can also affect radio wave propagation by absorbing or attenuating signals.
Is radio wave is a mechanical wave?
No, radio waves are not mechanical waves. They are a type of electromagnetic wave that do not require a medium (such as air or water) for propagation. Mechanical waves, on the other hand, require a medium to travel through.
