The Intelsat group.

Intelsat, S.A. is a communications satellite services provider.

It was originally formed as International TelecommunicationsSatellite Organization (INTELSAT), it wasfrom 1964 to 2001an intergovernmental consortium owning and managing a

constellation of communications satellites providinginternational broadcast services.

Intelsat operates a fleet of 52 communications satellites, whichis the world's largest fleet of commercial satellites.

Some more info.

Launched on 25 March 2012 at 12:10 GMT.

Expected life: 15 years.

Located at 72 degrees East Longitude over the Indian Ocean.

Launched from Baikonur, Kazakhasthan. Launch mass (kg): 6199

History of Proton M.

Lead designer was Vladimir Chelomei, who designed it Gross Liftoff with the intentionof creating both a powerful rocket for military payloads and a high-performance ICBM.

The program was changed, and the rocket was developed exclusively for launchingspacecraft.

First named UR-500, but adopted the name UDMH and NTO Proton, also was the name of the first three payloads launched.

Proton launched Russian interplanetary missions to the Moon, Venus, Mars, andHalleys Comet.

Proton launched the Salyut space stations, the Mir core segment and both the Zarya(Dawn) and Zvezda (Star) modules for todays International Space Station.

First commercial Proton launch 9 April 1996. First commercial Proton M Breeze M launch 30 December 2002

Technical details of Proton M.

The Proton Briz-M rocket launcher is equippedwith R-4D, four SPT-100 plasma thrusterspropulsion system. It was designed and built by

the Khrunichev State Research and SpaceProduction Center of Moscow.

Its designation was derived from the 'Proton'rocket and the 'Briz-M' booster stage.


13/22

Communications payloads.

Three distinct communications payloads.

48 channel C-band payload with 36 MHzchannels

24 channel Ku band payload with 36 MHzchannels

18 channel UHF payload with 25 kHz channels.


14/22

Is-22 C-band payload

The Intelsat 22 C-band payload consists of 48operational 36 MHz channels.

Two antennas provide service to the Africa and

Asia regions. There is some cross connect capability

between the two regions.


15/22

Is-22 Ku-band payload

The Intelsat 22 Ku-band payload consists of 24operational 36 MHz channels.

Coverage for the Middle East, Africa, and

Europe.


16/22

Is-22 UHF payload

The UHF payload consists of 18 operational 25kHz channels.

Added to the Intelsat 22 satellite as a result of

the contract with ADF. (The Australian DefenseForce (ADF) signed a $167 Million contract withIntelsat for the UHF payload on the Intelsat 22satellite for 15 years of service)

Earth Stations.

Ground control handled by Boeing Space andIntelligence Systems (BSIS)' Intelsat-22

The IS-22 can be controlled by four operationalcentres, which include Africa, Asia, Middle East andEurope, using ground control equipment hardwareand software. The ground station is designed andmanufactured by BSIS.

It is equipped with telemetry tracking and command(TT&C) system to monitor and control the spacecraftthrough commands.


21/22

Applications.

The IS-22 is equipped with 48 C-band and 24 Ku-band 36MHz equivalenttransponders to offer services to network providers, government and mediacustomers in Africa, Asia, Europe and the Middle Eastern regions.

It boasts 18 UHF active high power transponders of 25kHz bandwidth torender services to the Australian Defence Force (ADF). The UHF band is

deployed for military applications due to its adaptability to compact andmobile terminals used by ground, sea and air force.

The spacecraft renders possible solutions for audio, video and dataservices using small earth stations in Europe, Africa, the Middle East, theIndian Ocean and Asian regions. It also enables broadband connectivity inaircraft and ships.
