A satellite navigation system uses a network of satellites to provide geo-spatial positioning by calculating the location of a receiver on Earth from signals from multiple satellites. There are currently two global satellite navigation systems, GPS and GLONASS, as well as two more in development, Compass and Galileo. Satellite phones connect to communications satellites instead of terrestrial cell towers to provide mobile service anywhere. They have both military and civilian applications including precision weapons guidance, aircraft passenger information, and personal satellite communications.

2. A satellite navigation system a.k.a. sat nav system is a system of
satellites, usually managed by one company or a country that provides
geo-spatial positioning, which is a technical term for a specific location
on or above the Earth in 3 dimensions.
Sat Nav system
Sat Nav systems use a
series of satellites placed
in specific orbits around
the Earth to figure out
where the Receiver is
located. The satellites
transmit orbital and
timing information. The
receiver uses this
information from several
satellites to calculate its
position. Commercial
systems are accurate to
couple meters, but high-
end systems are accurate
to a few centimeters.

6. In development 2
Compass is a global navigation system
being developed by China that will
consist of 35 satellites and is expected
to be completed in 2020. It is the 2nd
generation of its regional BeiDou
Satellite Navigation System(BDS), a.k.a.
BeiDou-2
Galileo is a 30-satellite global navigation
system being developed by the European
Union(EU) and European Space Agency,
expected to be completed in 2020. One of
the goals of this system is to provide a high-
precision positioning system for EU nations
i.e. independent of GLONASS, GPS, IRNSS

12. Sat Phone
A satellite telephone, or a sat phone is a type of mobile phone that
connects to orbiting satellites instead of terrestrial cell sites.

13. Inmarsat
 Only Inmarsat service
is permitted in India for
satellite communication.
International Long
Distance(ILD) licence and
No Objection Certificate
(NOC) issued by Indian
Department of
Telecommunications
(DOT) is mandatory for
satellite communication
services on Indian
territory.
 Import and operation
of all other satellite
services, including
Thuraya & Iridium, is
illegal
