ANELLO Photonics is a leading developer of inertial navigation solutions based on its disruptive SiPhOGTM (Silicon Photonics Optical Gyroscope) that provides accuracy and reliability paired with an unprecedented reduction in cost and SWaP (size, weight and power) footprint. ANELLO offers state of the art Inertial Navigation Systems (INS) and Inertial Measurement Units (IMU) that are meticulously crafted to meet the requirements of challenging commercial and defense operations in GPS-denied environments.

ANELLO’s solutions are ideal for the demanding navigation, positioning and motion tracking requirements of a wide range of drone, robotics, and autonomous vehicle applications as seen in precision agriculture, autonomous construction equipment, and defense robotics.

SiPhOG™ Technology

ANELLO’s disruptive SiPhOGTM (Silicon Photonics Optical Gyroscope) technology is a first-of-its-kind breakthrough, providing a smaller, lighter and more cost-effective alternative to traditional FOG sensors without sacrificing performance or quality.

The core of this is ANELLO’s groundbreaking technology that revolutionizes traditional fiber optic gyroscopes by replacing bulky discrete optical components with a patented silicon photonics integrated circuit. This innovative approach dramatically reduces both size and component costs, while maintaining high performance. In addition to this, an ultra-low-loss waveguide is being developed in collaboration with a prominent, well-established US-based commercial semiconductor foundry. This partnership ensures scalable manufacturing processes and future integration while paving the way for widespread adoption of ANELLO’s compact, high-precision navigation solutions across various industries and applications.
