The ANELLO Maritime INS has been precisely engineered to deliver high-precision navigation for surface and subsurface naval and marine platforms such as ASVs (autonomous surface vessels) and autonomous underwater vessels (AUVs) operating in challenging and GPS-denied environments.
Based around a three-axis SiPhOGTM unit combined with dual triple-frequency multi-constellation GNSS receivers, the Maritime INS offers a suite of advanced features including dead reckoning, cutting-edge sensor fusion, and GNSS spoofing detection. It features Ethernet, CAN and dual RS-232 interfaces, with position, velocity and attitude outputs at up to 100 Hz.
The compact and lightweight unit is IP68-rated and highly resilient against heavy shock and vibration, and has been engineered to be resistant to marine environmental conditions such as corrosion, salt spray and chemicals.
