WASHINGTON: The Space Development Agency (SDA) and the builder and operator of America’s spy satellites, the NRO, are discussing how to move imagery more rapidly from spy satellites to warfighters for targeting, SDA Director Derek Tournear tells me. The two agencies are working on “joint roadmaps where we’re planning on being able to integrate their layer and get to the Transport Layer,” he says in an exclusive interview. SDA’s plan is to combine data from NRO imaging satellites with data gathered from commercial imaging providers to provide operators with near-real time ground target tracking and targeting information via what SDA calls the “Custody Layer” of its National Defense Space Architecture.
