# ANELLO Photonics

> ANELLO Photonics is a Santa Clara, California semiconductor and navigation company that builds SiPhOG, described as the world's smallest high-precision silicon photonic optical gyroscope. By shrinking fiber-optic-class gyroscope performance onto a chip, ANELLO delivers inertial measurement units (IMUs) and full inertial navigation systems (INS) that keep vehicles, drones, ships and robots positioned accurately when GPS/GNSS signals are jammed, spoofed or simply unavailable - across land, air and sea. Founded in 2018 by silicon-photonics pioneer Dr. Mario Paniccia and MEMS/inertial-sensor veteran Mike Horton, the company serves defense, maritime, aerospace, agriculture, construction, mining and autonomous-vehicle markets.

- **Founded:** 2018
- **Headquarters:** Santa Clara, California, United States
- **Founders:** Mario Paniccia (Co-Founder & CEO), Mike Horton (Co-Founder & CTO)
- **Team size:** ~110 employees

- **Notable:** Built what it describes as the world's smallest high-precision silicon photonic optical gyroscope (SiPhOG)., Completed the world's first integrated SiPhOG with a $28M Series A in 2021., Secured a Series B co-led by Lockheed Martin, Catapult Ventures and One Madison Group (Nov 2024).

## Products & services

- **SiPhOG (Silicon Photonic Optical Gyro)** — Chip-scale integrated optical gyroscope delivering fiber-optic-class performance in a tiny, low-cost, low-power silicon photonics package. ANELLO describes it as the world's smallest high-precision optical gyroscope.
- **ANELLO X3 IMU** — A three-axis inertial measurement unit combining SiPhOG optical gyroscopes with MEMS accelerometers for high-accuracy, low-drift motion sensing.
- **ANELLO Ground IMU / Ground INS** — Inertial measurement and navigation units tuned for ground vehicles, construction, agriculture and mining where GPS is intermittent.
- **ANELLO Maritime INS** — Inertial navigation system for surface and unmanned maritime vessels operating in GPS-denied or contested waters.
- **ANELLO Aerial INS** — Inertial navigation system for UAVs and aerial platforms needing reliable positioning in urban canyons and GPS-jammed airspace.
- **ANELLO GNSS-INS Evaluation Kit** — Developer evaluation kit fusing GNSS with ANELLO's optical-gyro INS and sensor-fusion engine for rapid integration and testing.
