SSL SELECTED TO HELP U.S. AIR FORCE TEST AND VALIDATE SCENARIOS FOR HOSTING PAYLOADS

MacDonald, Dettwiler and Associates Ltd.'s Space Systems Loral (SSL) has been selected by Innoflight Inc., a veteran-owned business specializing in electronics systems for defence and aerospace, to provide a high-fidelity simulation environment for testing the security of hosted payloads on commercial satellites. The capability, which is being developed for the U.S. Air Force Space and Missile Systems Center (SMC) as part of its secure IP payload accommodation demonstration project, will enable SMC to demonstrate cybersecure payload hosting scenarios, concepts of operation and cybersecurity controls.

The capability will also demonstrate advanced, secure Internet protocol connections between a government payload operations centre and the hosted payload using the existing satellite operator's networking infrastructure, eliminating the high cost of specialized space to ground communication systems.

"SSL has significant experience integrating hosted payloads into our leading commercial spacecraft platform, the SSL 1300," said Richard White, president of SSL Government Systems. "Our commercial experience positions us well to provide the precise test environment that Innoflight requires to demonstrate how its secure interface solution will ensure cybersecurity for U.S. government missions. This work will become an integral part of SSL's secure interface for hosted payloads, and will make the benefits of the hosted payload model more readily accessible to both government and commercial customers."

The hosted payload interface is expected to play a key role in enabling resilient, next-generation space architectures.

"A key factor in our selection of SSL to work with us in support of SMC was the company's leadership in commercial satellite design," said Jeffrey Janicik, president of Innoflight. "Our test environment will benefit from SSL's global reach and high-level experience with hosted payloads and secure communications."
