Honeywell Adds Layers to GPS Anti-jam Prevention

Honeywell's lightweight Compact Inertial Navigation System and Radar Velocity System help prevent jamming of global navigation satellite systems.

After developing the GPSDome anti-jamming system with InfiniDome, Honeywell (Stand 1432) has added two more layers of protection, systems that don’t rely on GPS and thus help protect against jamming. GPSDome is a first layer of protection, offering protection against low-power GPS jamming. The new Compact Inertial Navigation System (CINS) and Radar Velocity System (RVS) add two more layers of protection.

With CINS, Honeywell engineers were able to pack tactical-grade INS sensors into a package “about the size of a deck of cards,” the company said. That allows aircraft to continue navigating during periods of shorter global navigation satellite system (GNSS) outages. Honeywell sees CINS as “especially useful in urban canyons where GNSS availability is intermittent or in strong jamming environments where anti-jamming systems are not enough.”

For longer GNSS outages, RVS provides a radar-based navigation-aiding system.

The new technologies and others under development at Honeywell, including in partnership with InfiniDome, are designed for air, land, and sea vehicles, “to readily handle signal disruption and maintain access to critical navigation and timing information,” Honeywell said. Other applications will include autonomous vehicles, special purpose commercial vehicles, and personal navigation.

“The industry is demanding a rapid solution to address issues like jamming and spoofing that cause disruptions,” said Honeywell Aerospace vice president for navigation and sensors Matt Picchetti. “We are confident that with the launch of our new industry-leading navigation systems, our commercial and military customers will finally have access to a system that allows continued operations even in GNSS disrupted or denied environments.”
