SOLAR SYSTEM

Detailed explanation-1: -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.

Detailed explanation-2: -The Ultra High Frequency Satellite Communications (uhf satcom) System provides communication links, via satellite, between designated mobile units and shore sites worldwide in the Ultra High Frequency band beyond the line of sight. It is immune to weather issues and can penetrate deep forest cover.

Detailed explanation-3: -Microwaves are best suited to communicate with geostationary satellites since they have a higher frequency and small wavelength. They are not the best for communication with satellites in low orbit.

Detailed explanation-4: -Mobile phones communicate to a mobile cell tower using radio waves, towers communicate with satellites using microwaves. Microwaves are used as they can pass through the atmosphere. This signal can be sent to a satellite and used to communicate around the world (more than one satellite is required for this).

Detailed explanation-5: -1 Answer. The explanation is: Communication satellites are not originators of information to be transmitted. If a transmitting station cannot communicate directly with one or more receiving stations because of line-of-sight restrictions, a satellite can be used.

Detailed explanation-6: -Satellite modems are used for satellite transmissions.
