Intelsat 22, is a communications satellite in geostationary orbit and constructed by Boeing Space Systems for the Intelsat Corporation.[2][3] The satellite was planned to be located at 72° East Longitude over the Indian Ocean.
The Australian Defence Force (ADF) signed a US$167 million contract with Intelsat for the UHF payload on the Intelsat 22 satellite for 15 years of service.[4]
Communications payloads
[edit | edit source]Intelsat 22 had three distinct communications payloads. A 48 channel C-band payload with 36 MHz channels, a 24 channel Ku-band payload with 36 MHz channels, and an 18 channel Ultra high frequency (UHF) payload with 25 kHz channels.
C-band payload
[edit | edit source]The Intelsat 24 C-band payload consists of 48 operational 36 MHz channels. Two antennas provide service to the Africa and Asia regions. There is some cross connect capability between the two regions.
Ku-band payload
[edit | edit source]The Intelsat 18 Ku-band payload consists of 24 operational 36 MHz channels with coverage for the Middle East, Africa, and Europe.
UHF payload
[edit | edit source]The UHF payload consists of 18 operational 25 kHz channels which were added to the Intelsat 22 satellite as a result of the contract with ADF (Australia).
Launch
[edit | edit source]Intelsat 22 was launched on 25 March 2012 at 12:10:32 UTC.[3]
