Anello Photonics said it has secured an additional $25 million in Series B-2 funding to accelerate production of its GPS-denied navigation systems, as demand grows for resilient positioning technologies in contested environments. The company develops silicon photonics–based optical gyroscopes designed to provide precise navigation without relying on satellite signals, targeting applications across defense, autonomy and industrial markets.
The funding round, which follows earlier government backing and defense contracts, will support scaling manufacturing and expanding deployment of the company’s inertial navigation solutions. Officials said the technology enables reliable operation across land, air and sea platforms where GPS signals may be jammed or unavailable, a growing concern in both military and commercial sectors.

Anello’s systems combine its Silicon Photonics Optical Gyroscope with AI-based sensor fusion to deliver high-precision positioning in GPS-contested environments. The company said the additional capital will help accelerate commercialization and meet increasing demand from autonomous systems and national security programs.
The investment comes amid rising competition in the GPS-denied navigation market, with companies such as Advanced Navigation, SBG Systems and VectorNav Technologies developing alternative inertial and sensor-fusion solutions. As reliance on satellite navigation faces growing vulnerabilities, the race to provide resilient, non-GNSS positioning systems is intensifying across both defense and commercial industries.
