The United States Naval Observatory (USNO) has selected NovAtel’s GPS Anti-Jam Technology (GAJT) to satisfy a requirement for a controlled reception pattern antenna capability at sites throughout the Department of Defense Information Network (DoDIN).

The DoDIN is the core global enterprise network of the United States military and is depended upon for secure and sensitive voice, data, video and bandwidth services. This latest order brings the number of NovAtel GAJT antennas ordered by the U.S. Navy to more than 600.

GAJT protects GPS-based navigation and precise timing receivers from intentional jamming and accidental interference. It is a null-forming antenna system that ensures satellite signals necessary to compute position and time are always available.

The commercial off-the-shelf product comes in versions suitable for land, sea, fixed installations and smaller platforms such as UAVs. Military vehicles and platforms, networks and timing infrastructure also benefit from the protection that GAJT provides. There is no need to replace GPS receivers already installed, as GAJT works with civil and military receivers, and is ready for M-code, according to NovAtel.

NovAtel’s manufacturing techniques and quality processes mean that that the company can ramp up quickly to meet volume requirements, the company said.

“This order underlines our ability to deliver GAJT in volume and on time,” said Michael Ritter, president and CEO of the Canada-based NovAtel. “GAJT has now been shipped and is in use operationally by 12 allied nations around the globe. We are grateful for the rigorous technology selection process conducted by USNO which led to this latest order.”

The U.S. Naval Observatory is located in Washington, D.C.

Located in Washington, D.C., the USNO is one of the oldest scientific agencies in the United States, with a primary mission to produce Positioning, Navigation and Timing for the United States Navy and the United States Department of Defense.
