This document discusses satellite phones, including their operation through satellite networks, their uses in remote areas without reliable cellular service, and their current and future applications. It describes geosynchronous and low earth orbit satellite networks, lists some providers and phone models, and outlines the general costs and restrictions on using satellite phones. The document concludes by noting satellite phones remain an important innovation for communication, especially in remote locations, and that their use and applications are still expanding.

3. Introduction
Vital communication tool in remote areas.
Important in areas where local Telecom are unreliable.
Termed as SATPHONE.
As it’s own drawbacks & advantages.
Still greatest Innovation.

4. SATELLITE
Every Satellite
Phone operates on the Satellite
Principal

5. Diagrammatical logic of SATPHONE
The picture
aside shows
us the logical
operation
behind Mobile
TV phones
that work on
satellites
,same kind of
logic is used
while
considering
SATELLITE
PHONES.

6. Satellite Phone Networks

7. Satellite Phone
Networks
Geosynchronous Network:
Remain in Fixed position in the Sky at all
times.
Global coverage maintained by 3-4 satellites
& thus reduce cost .
Very heavy and Expensive to build .
Amount of available bandwidth is much
higher than LEO networks .
The main disadvantage is that connection
between the phone and the satellite breaks
quickly.

8. Types of geosychronous
network
Geosynchronous
Network
ACeS Inmarsat Thuraya MSAT /
Terrestar ICO
SkyTerra

9. Satellite Phone
Networks
Low Earth Orbit Network:
worldwide wireless coverage with no gaps .
LEO satellites orbit the earth in high speed
They fly complete orbits
a usable pass of an individual LEO satellite will
typically last 4–15 minutes on average

10. Types of low earth orbit
network

11. Scope of satphone
North
Korea
India (proper
permission
reqd.)
Cuba
Libya
Syria
Burma

12. Cost of satellite phones
The Thuraya, Iridium, and Globalstar
networks provides satphone for
US$200.
The Iridium 9505A, costs nearly
$1,000 USD new.
The price of handsets varies with the
performance of the network.
Among the most expensive satellite
phones are BGAN terminals.
Satellite phones are manufac. Under
a standard & thus are unavailable for
manufactures to build it locally.
The least expensive phone made by
any company recently is the IsatPhone
Pro produced by the IMMARSAT.

13. Applications of Satellite Phones
Applications:
Handheld
Internet
 Car Kits
Marine
Aviation
 Video
Secure
 Fax
Fixed Sites

14. Future Prospects
So we can say that Satphone is one of the
greatest innovation in communications.
It can help local users from simple persons to
business men's.
It also is applicable in military uses.
Use, of satphone as been still not made
properly.
One of the example is the Terrorists uses.
So, nowadays each nation is now trying to get
as much as satisfaction or use from the Satellite
Phone.
