Satellite Telephony Operator

Satellite telephone operator - a telephone company that provides communication services through space radio communications . Satellite telephone subscribers have the opportunity to communicate with each other, as well as with other users of the global public telephone network . Subscribers of satellite telephone communications receive a standard telephone number from the special ranges of telephone zone 8 , indicating that they belong to satellite communications.

The following satellite telephone number prefixes are known:

• +870
• +871
• +872
• +873
• +874
• +881
• +88216

In order to use the telephony services of a satellite operator, special equipment is needed - a satellite phone , VSAT and satellite modem or mobile satellite station .

Satellite telephone communications are in demand in those parts of the globe where other methods of telephone communications are impossible - in space, in orbit around the planet Earth (used by astronauts ^{[1] [2]} ), at the north and south poles , in the ocean , on islands , etc. P.

Depending on the telecom operator, the scope may be either the entire Earth , or individual regions of the world. This is due to the fact that either low-flying satellites are used , which, with a sufficient amount, cover the entire Earth, or satellites in a geostationary orbit , where they do not move relative to the Earth and do not “see” it completely.
