NovAtel Announces New GPS Anti-Jam System

Published: 26 May 2019

GAJT-410 GPS Anti-Jam AntennaNovAtel has announced an addition to the company’s GPS Anti-Jam Technology (GAJT) portfolio, the GAJT-410ML. Designed specifically for rapid integration into space-constrained military land applications such as UGVs (unmanned ground vehicles) and other robotic platforms, this easy-to-use system protects GPS-based navigation and precise timing receivers, including M-Code, from both intentional and accidental interference.

The GAJT-410ML is the next evolution of NovAtel’s battle-proven anti-jam technology. It maintains the high levels of interference rejection performance as in the larger GAJT-710ML system, but in a lower size, weight and power (SWaP) design. Working alongside the GAJT-410ML, the Power Injector Data Converter (PIDCTM) provides access to the jammer status and direction-finding (DF) information. It also provides clean power and data over the same cable that delivers the protected GPS signal back to the receiver, which reduces the need for costly platform modifications. The PIDC can be supplied in either an enclosure or board and is available to license for installation into third-party equipment.

NovAtel Defence Segment Manager, Dr. Dean Kemp, noted: “Building on the success of our existing anti-jam portfolio, the GAJT-410ML is the first system to address the needs of smaller land-based platforms and add situational awareness capability to already high levels of mitigation performance.” Dr. Kemp added: “This product offers more choices for system integrators and end users to protect against GPS denied or constrained situations and delivers on our commitment to provide assured positioning anywhere.”
