A satellite telephone, satellite mobile phone, or satphone is a phone that connects directly with orbiting communications satellites. Depending on the architecture of a particular system, coverage may include the entire Earth, or just specific portions.
The mobile tools, generally known as a terminal or earth station, varies widely. A satellite phone handset has a measurement and weight comparable to that of a late nineteen eighties or early on 1990s mobile phone, but usually with a large retractable antenna. These are popular on adventures into faraway places where terrestrial mobile service is out of reach.
A fixed installation, like used shipboard, may include large, rugged, rack-mounted electronics, and also a steerable microwave antenna on the mast that instantly tracks the overhead satellites. Satellite phones have notoriously inadequate reception indoors, although it can be possible to get a continuous network near a window or in the top floor of a structure if the roof is sufficiently thin. The phones have connectors for external antennae that are usually installed in vehicles and architecture.
Several satellite phones use satellites in geosynchronous orbit. These systems can maintain near-continuous global signal with only 3 or 4 satellites, reducing the launch costs.
The negative aspect of geostationary satellite systems is that many locations even where a very clear view of the sky is present the line of sight among the phone and the satellite is destroyed by obstacles such as steep mountain hills and jungle and the consumer needs to find higher landscape before being able to use the phone. This is not the case with Low Earth Orbit (LEO) services - though the coverage is stuck by an obstacle anyone can wait a few minutes till another satellite passes overhead.
