Advanced Navigation, an Australia-based developer of inertial navigation and autonomous sensing technologies, has announced new investment aimed at accelerating the development of PNT systems designed to operate in environments where GNSS signals are degraded or unavailable.
The company said the funding will support expansion of its portfolio of navigation technologies that integrate inertial sensors, AI-driven perception systems and sensor-fusion software to maintain accurate positioning in GNSS-denied environments. The technologies are intended for applications across aerospace, defense, robotics and maritime operations.
Focus on GNSS-Resilient Navigation
Advanced Navigation’s core technology stack centers on high-performance inertial navigation systems (INS) combined with advanced sensor fusion algorithms. These systems use data from inertial measurement units (IMUs), computer vision, acoustic sensors and other onboard inputs to estimate position and orientation when satellite navigation signals cannot be relied upon.
Such capabilities are increasingly important as GNSS disruption—whether through interference, jamming or spoofing—has become more common in both civilian and defense operating environments.
Chris Shaw, co-founder and CEO of Advanced Navigation, said the company’s goal is to enable autonomous systems to maintain reliable navigation even in complex operating conditions.
“Our mission is to deliver navigation and autonomy technologies that allow systems to operate reliably across sea, land, air and space,” Shaw said in a statement.
Inertial navigation systems play a central role in these architectures. While INS solutions can maintain navigation continuity without external signals, they accumulate error over time due to sensor drift. Modern navigation stacks therefore rely on sensor fusion techniques that combine inertial measurements with other inputs—such as visual landmarks, lidar data or acoustic signals—to correct drift and maintain accuracy.
Expanding the Alternative PNT Ecosystem
Demand for complementary PNT technologies has grown rapidly as governments and industry seek alternatives to exclusive reliance on satellite navigation. Recent disruptions in regions such as the Black Sea, Eastern Europe and the Middle East have highlighted the operational risks posed by GNSS interference.
Companies developing resilient navigation architectures are increasingly integrating multiple sensing modalities—including visual navigation, signals of opportunity and advanced inertial systems—to provide robust positioning capability when satellite signals are unavailable.
Advanced Navigation has focused on combining high-performance hardware with artificial intelligence-based perception systems. These technologies are intended to support autonomous platforms operating in complex environments such as urban areas, indoor facilities, underground infrastructure and subsea environments.
Applications Across Autonomous Systems
The company’s navigation technologies are used across a range of autonomous platforms including unmanned aerial vehicles, autonomous underwater vehicles, ground robots and maritime vessels. These platforms require reliable navigation even when operating in environments where GNSS reception is blocked or intentionally disrupted.
Advanced Navigation said the new funding will allow the company to accelerate development and global deployment of its navigation technologies while expanding manufacturing capacity.
As autonomous systems become more widely deployed across commercial and defense sectors, resilient navigation architectures that integrate inertial sensing, perception and AI-driven sensor fusion are expected to play a central role in next-generation PNT systems.
