ANELLO Maritime INS

High-performance inertial navigation for autonomous surface and underwater vessels in GPS-denied environments.

The ANELLO Maritime INS combines three SiPhOG™ optical gyroscopes, dual triple-frequency GNSS, and maritime sensor fusion to deliver low-drift position, velocity, and attitude through GNSS jamming, spoofing, and outages.

Frequently Asked Questions

What is the ANELLO Maritime INS?
It is an optical inertial navigation system that continuously estimates position, velocity, roll, pitch, and heading for maritime platforms, including when GNSS signals are unavailable or unreliable.
What sensors and systems can it integrate with?
The system supports dual triple-frequency GNSS, Doppler velocity logs, speed-through-water sensors, and optional external aiding. Platform connectivity includes Ethernet, dual RS-232, CAN, and PPS synchronization.
Which maritime platforms is it designed for?
The compact INS is designed for USVs, ASVs, AUVs, UUVs, crewed vessels, port-security systems, and coastal-defense platforms.
Is the system suitable for harsh marine environments?
Yes. The ANELLO Maritime INS is ITAR-free and IP68-rated, with 5g rms vibration performance, 40g shock survival, and an optional extended operating-temperature range.
