Lockheed Martin Opens Test Site To Monitor Objects In Space

Lockheed Martin officially opened up a test site to monitor objects in space by a radar array for the US Air Force’ Space Fence at New Jersey.

There is also a test site under construction in Kwajalein Island and will be used for early validation of hardware, firmware and software that will enable the Space Fence to detect, track, and catalog orbital objects more than 1.5 million times a day to predict and prevent space-based collisions, the company said in a statement Tuesday.

The test site will also provide early lessons learned on installation of the S-band ground-based radars, support maintenance training and allow engineers to test verification procedures.

The New Jersey test site officially opened during a ceremony attended by representatives from the USAF, local, state and federal governments, Lockheed Martin leaders and Space Fence team members.

Bruce Schafhauser, director, Lockheed Martin Space Fence says, "We are one step closer to improving space situational awareness and increasing orbital debris monitoring by tenfold. By using an open-architecture system, Space Fence can adapt to future missions requiring various tracking and coverage approaches."

Within the Space Fence radar design, Lockheed Martin uses the latest monolithic microwave integrated circuit technology, including Gallium Nitride (GaN) semiconductor materials. GaN provides significant advantages for active phased array radar systems, including higher power density, greater efficiency and improved reliability over previous technologies.

Construction continues at the six-acre Space Fence site 2,100 miles southwest of Honolulu. Forty-five hundred cubic yards of concrete now form the foundation of the sensor site and the start of ring walls (left) that will support the inflatable roof permeable by RF bands.

Once construction is complete, Space Fence will be tested and validated before its Initial Operating Capability occurs in late 2018.
