Boeing has successfully completed the critical design review (CDR) of the Intelsat 22 satellite (IS-22) and its ultra-high-frequency (UHF) hosted payload.

IS-22 will provide commercial video, network and voice services to Intelsat’s customers throughout the Indian Ocean region.

The UHF payload, which is built by Boeing, is being placed on the satellite to be used by the Australian Defence Force (ADF) by Intelsat.

The reviews included documentation and analysis of all aspects of the satellite’s design including assembly, integration, testing and safety requirements.

Before the review, the firm conducted risk reduction tests on its engineering development unit UHF Antenna including thermal passive intermodulation tests (thermal PIM) and thermal vacuum multipactor tests.

Boeing Space & Intelligence Systems vice-president and general manager Craig Cooning said that successfully completing the final design review has allowed the company to begin assembly, integration and environmental testing of IS-22.
