Question

which is most suitable means of reliable continuous communication between orbiting satellite and earth???​

Answer 1

One is to use relays, either connected ground stations or other satellites, spread along the satellite's orbital track to carry the signal back to your original ground station. The other is to place it in a geostationary or geosynchronous orbit.

Answer 2

Answer:

Microwaves

Explaination:

Microwaves have high frequency and can pass through the atmosphere of earth to reach higher orbit satellites. Microwaves are least affected by different levels of atmosphere.Microwaves travel in straight lines and are not affected by the ionosphere.Microwaves are less affected by temperature inversions and has less scattering also.
