GNSS/INS guides autonomous vessels during naval forces’ critical missions

Saronic, a Texas-based company, is leveraging the latest cutting-edge technology for their Autonomous Surface Vessels (USVs) used in naval critical missions. These vessels are equipped with advanced sensors for enhanced domain awareness in contested waters. They are designed for tactical deployment, alone or in collaborative swarms, via at-sea launch and recovery from expeditionary craft. Saronic selected AsteRx SBi3 Pro+ GNSS/INS (Inertial Navigation System) receiver for resilient positioning and orientation for navigating in the most challenging environments. AIM+ Advanced Interference Mitigation technology protects Septentrio receivers from jamming and spoofing attacks which threaten to disrupt GNSS-based navigation.

“At Saronic, we’re focused on developing the most intelligence Autonomous Surface Vessels (ASVs) to support naval and maritime forces’ critical missions. Septentrio’s technology enables our autonomous capabilities and, working alongside other onboard sensors, provides enhanced redundancy and reliability. We value our partnership with Septentrio and believe they deliver world-class technologies that enable secure and robust operations in even the harshest environments.”

Why did Saronic choose AsteRx SBi3 Pro+

  • Advanced jamming and spoofing mitigation for positioning availability even under high-power interference (see results report from JammerTest in Norway)

  • Proven best-in-class anti-spoofing detection for situational awareness, even during the most sophisticated coherent spoofing or meaconing attacks

  • Multi-frequency multi-constellation GNSS technology for high-accuracy positioning and optimal signal availability and signal fallback during interference attacks 

  • FUSE+ technology for sub-degree INS heading, pitch and roll angles (3D orientation) 


Saronic is building cutting-edge unmanned surface vehicles that enable maritime security and domain awareness by combining best-in-class hardware, software and artificial intelligence into one scalable, fully integrated platform. Through improved sensors and surveillance systems, advanced communication technologies and enhanced situational awareness tools Saronic enables military commands to better detect, track and respond to potential threats in the maritime domain.
