Jamming and spoofing have made global navigation satellite system (GNSS) signals less dependable, and Honeywell Aerospace is answering with an expanding menu of alternatives. At a recent JamFest demonstration event in Barcelona, Spain, the Phoenix-based company showcased smaller-form products—spanning radar velocity, visual, and low-earth-orbit (LEO) navigation—that build on its inertial navigation systems (INS) expertise.
“There’s no one silver bullet with alternative navigation modalities,” explained Darren Fisher, a founding member of Honeywell’s HGuide navigation business unit. The world has “really sat up and noticed” the effect of deliberate spoofing or jamming on traditional GNSS signals over the past five years, Fisher said, making it useful to mix navigation methods and give customers “an à la carte approach” based on mission requirements. That flexibility matters because each method carries limitations tied to terrain, weather, and size or weight.
