The Intelsat-22 satellite is planned for launch in early 2012 and will be carrying a UHF Hosted Payload on-board for use by the Australian Defence Force (ADF). This state of the art satellite will provide the ADF with tactical communications for their military at a cost savings of $150M over the cost of a dedicated satellite to provide the same capability. The spacecraft will be positioned over the Indian Ocean at 72°EL.
In addition to the UHF hosted payload Intelsat General Corp (IGC) is delivering to the ADF a turn-key dualoperation UHF Communication System Monitoring (CSM)and In Orbit Testing (IOT) system. This system is being installed at the ADF naval base HMAS Stirling in Perth Australia and is devised to confirm the RF performance and integrity of the UHF payload on the spacecraft both during the hosted payload’s initial In-Orbit Testing phase and throughout its operation. The system is equipped to confirm the performance and integrity of other UHF legacy payloads on satellites operating over the geostationary arc as seen from Perth.
The CSM-IOT system is a fully integrated solution incorporating the most advanced commercial- off- the- shelf (COTS) products on the market integrated together using system engineering and project management methodologies to deliver customized capabilities. COTS products are popular in many industries including the space industry owing to their flexibility, maturity, scalability and low cost.
To devise an efficient system, you need flexible and proven products that meet all the requirements while minimizing customization. But at the same time, you need to maximize performance. It is also vital to ensure that the system can readily grow with the customers’ changing needs once deployed. It is very important to ensure that proper documentation and training are provided. In this case that means allowing the ADF to tailor the system to fit any of their operational scenarios once deployed.
The IGC CSM-IOT system will offer the following capabilities:
· In orbit acceptance test (IOT)
· Baseline performance measurements
· Operational Carrier monitoring
· Monitor and control
Key system components of IGC’s CSM-IOT include:
· RF: Encompassing the antenna and RF subsystem.
· CSM: Encompassing the carrier monitoring requirements and associated baseband and data processing equipment.
· IOT: Encompassing the In Orbit Test requirements for the payload and can also be used for annual payload performance measurements and other payload verification, as required.
· M&C: Encompassing a unified monitor & control interface to all pieces of the system. Thus, allowing for an ADF customized interface.
The comprehensive solution presented by IGC is also capable of monitoring a full spectrum of frequency bands: UHF, L, X, C, Ku or Ka-band for active or passive foreground and background measurements, when connected to the appropriate RF chains.
IGC’s success in delivering this powerful and flexible system stems from our unique systems engineering experience. This expertise ties together all aspects of the project to ensure that individual parts, subsystems, support equipment and associated operational equipment effectively function as one. This end to end coordination is critical for the IS-22 Hosted Payload to meet the operational requirements of the ADF’s military concept of operations (CONOPS).
