The low-orbiting NRO spacecraft include Keyhole optical imaging satellites, radar satellites such as Topaz and Lacrosse and low-orbiting electronic intelligence satellites. Additionally, the system is tasked with communications relay for airborne and ground-based Air Force Satellite Communications terminals with special focus on the polar regions. For that, the Satellite Data System uses a combination of satellites in a Geosynchronous Orbit and spacecraft in highly elliptical Molniya orbits that allow coverage of the polar regions.
