Intelsat 22, with the International Designator of the Committee on Space Research (COSPAR ID) 2012-011A is a satellite constructed by Boeing Space Systems for the Intelsat Corp.[2][3] The satellite was planned to be located at 72 degrees East Longitude over the Indian Ocean.
The Australian Defence Force (ADF) signed a $167 Million contract with Intelsat for the UHF payload on the Intelsat 22 satellite for 15 years of service.[4]
Communications payloads
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 UHF payload with 25 kHz channels.
C-band payload
The Intelsat 22 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.
Is-22 Ku-band payload
The Intelsat 22 Ku-band payload consists of 24 operational 36 MHz channels with coverage for the Middle East, Africa, and Europe.
Intelsat 22 UHF payload
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.
Launch
Intelsat 22 launched on 25 March 2012 at 12:10 GMT.[3]
