"SiPhOG" c/o ANELLO Photonics

Historically, precision navigation has relied on fiber optic gyroscopes (FOGs) — bulky, costly systems used in ICBMs, fighter jets, and submarines. ANELLO Photonics collapses that complexity into a silicon chip. Their breakthrough, the SiPhOG™ (Silicon Photonics Optical Gyroscope), miniaturizes the physics of FOGs using integrated photonics, resulting in a coin-sized device that delivers the precision of a fiber-optic gyroscope at a fraction of the size and cost. Unlike MEMS gyros found in smartphones — which are small but imprecise — SiPhOG offers long-duration inertial guidance without GPS, enabling autonomy in drones, robots, autonomous vehicles, underground mining vehicles, and even maritime vehicles. By leveraging silicon photonics — a field ANELLO’s team pioneered at Intel — the SiPhOG is immune to vibration, temperature shifts, and electromagnetic interference, while being scalable for mass production. The SiPhOG fills the precision gap between low-end MEMS and high-end fiber optic gyroscopes — opening up an entirely new layer of autonomy infrastructure. In an era where GPS signals are routinely jammed or spoofed, ANELLO’s chip-scale solution delivers resilient, high-fidelity navigation across land, air, and sea.
