A satellite telephone, satellite mobile phone, or satphone is a mobile that communicates immediately with orbiting communications satellites. Depending on the structure of a specific system, coverage may include the entire Earth, or just precise regions.
The phone equipment, also called a terminal or perhaps earth station, varies widely. A satellite phone handset has a dimension and weight similar to that of a late 1980s or early on 1990s mobile phone, but mostly with a large retractable antenna. These are well-liked on getaway into remote places where terrestrial cell service is beyond reach.
A fixed set up, such as used shipboard, include large, rugged, rack-mounted electronics, as well as a steerable microwave antenna on the mast that instantly tracks the overhead satellites. Sat phones have notoriously inadequate reception indoors, although it can be possible to get a constant signal near a window or even in the top floor of a structure if the roof is properly thin. The phones have connectors for external antennae that are frequently installed in vehicles and residences.
Several satellite phones use satellites in geosynchronous orbit. These systems can maintain near-continuous global network with only 3 or 4 satellites, reducing the launch expenses.
The negative aspect of geostationary satellite systems is that many places even where a very clear view of the sky is present the line of sight between the mobile phone and the satellite is ruined by obstacles like steep hills and forest and the consumer will need to find higher landscape before being able to use the mobile phone. This is not the scenario with Low Earth Orbit (LEO) services - even though the coverage is obstructed by an obstacle you can wait a few minutes till another satellite passes overhead.
