Satellite Features
The Intelsat 22 satellite is equipped with a range of transponders to provide services to various regions. It has 48 C-band transponders, which are used to offer services to network providers, government, and media customers in Africa, Asia, Europe, and the Middle Eastern regions.
The satellite also boasts 24 Ku-band transponders, which are equivalent to 36MHz bandwidth, and are used to provide services to the same regions as the C-band transponders.
The Intelsat 22 has 18 UHF active high power transponders, each with a bandwidth of 25kHz, specifically designed for military applications and deployed for the Australian Defence Force (ADF).
Critical Design Review for Communications Satellite
The critical design review for the communications satellite, IS-22, was completed in July 2010. This thorough review ensured the satellite's design was sound and ready for launch.
The IS-22 satellite has been designed to last for an impressive 18 years. Its weight at launch is around 6,199kg.
It features two unfolded solar arrays that can provide electrical energy in the event of a power system failure. This is a crucial backup system to ensure the satellite remains operational.
The satellite's design allows for polarisation of C-band and Ku-band, which are circular and linear respectively. This is important for ensuring reliable communication signals.
The uplink frequency of the C-band ranges from 5,850MHz to 6,425MHz, while the downlink frequency ranges between 3,625MHz and 4,200MHz. The Ku-band uplink frequency ranges from 14GHz to 14.5GHz.
Intelsat was awarded a $167m contract by the Australian Defence Force (ADF) for the ultra high frequency (UHF) payload on-board the IS-22 spacecraft. This contract will provide military satellite communication services to the ADF for 15 years.

Transponders on Board
The IS-22 satellite is equipped with a total of 48 C-band transponders and 24 Ku-band transponders, offering services to customers in Africa, Asia, Europe, and the Middle Eastern regions.
These transponders have a 36MHz equivalent bandwidth, which is quite impressive. The Ku-band transponders, in particular, are a great asset for providing high-speed data services to customers.
The IS-22 also boasts 18 UHF active high power transponders, each with a 25kHz bandwidth. This is a significant feature, as it allows for the deployment of services to the Australian Defence Force (ADF).
The UHF band is highly adaptable and can be used with compact and mobile terminals, making it ideal for military applications. This is a testament to the satellite's versatility and flexibility.

Ground Control and Support
Ground control of the Intelsat-22 is a crucial aspect of its operation. It is handled by Boeing Space and Intelligence Systems.
The TT&C system is a key component of ground control, allowing for real-time monitoring and command of the spacecraft. This system enables ground control teams to track the satellite's performance and make adjustments as needed.
With the TT&C system in place, ground control can remotely command the satellite to perform various tasks. This level of control is essential for maintaining the satellite's health and ensuring it continues to operate effectively.
