Gyroscope-on-a-Chip Targets GPS’s Dominance Centimeter-scale wayfinding accuracy emerges from millimeter-scale tech
This year, two companies—Santa Clara, California-based Anello Photonics and Montreal-based One Silicon Chip Photonics (OSCP)—have introduced new gyroscope-on-a-chip navigation systems, allowing for precise heading and distance tracking without satellite signals.
Such inertial navigation i increasingly important today, because GPS is susceptible to jamming and spoofing, which can disrupt navigation or provide misleading location data. These problems have been well-documented in conflict zones, including Ukraine and the Middle East, where military operations have faced significant GPS interference. For drones, which rely on GPS for positioning, the loss of signal can be catastrophic, leaving them unable to navigate and sometimes resulting in crashes.
