Poseidon International Group (Hong Kong) Limited — Connecting the World Through High Accuracy Navigation Technology
Based in Hong Kong, we are a global enterprise dedicated to delivering high-quality products and professional services. We have established long-term, stable, and efficient partnerships with numerous suppliers worldwide, ensuring competitive pricing and superior product quality.
As a leading supplier of Inertial Measurement Systems, we specialize in high-precision sensors, integrated navigation algorithms, and customized hardware components. Our engineering excellence enables us to supply high-reliability solutions designed to meet the rigorous demands of global markets, including the strategic commercial and industrial sectors of Greece.
Harnessing industry-leading expertise in sensor fusion and hardware design.
State-of-the-art facilities ensuring ISO-compliant quality control standards.
Unlocking new frontiers in maritime navigation, defense modernization, and civil infrastructure across the Hellenic Republic.
Greece holds the world's largest merchant fleet. Modern Greek shipping companies are rapidly adopting autonomous navigation, smart vessel management, and unmanned underwater vehicles (UUVs). Our high-precision Fiber Optic Gyroscopes (FOG) and MEMS-based Inertial Measurement Units (IMUs) provide reliable heading, pitch, and roll data, ensuring safe transit through the complex waterways of the Aegean and Ionian Seas, even during GNSS outages.
With its strategic geopolitical position in the Eastern Mediterranean, Greece continuously modernizes its defense capabilities. Unmanned Aerial Vehicles (UAVs), patrol vessels, and border surveillance equipment require robust, anti-jamming navigation hardware. Poseidon's integrated navigation systems offer military-grade resilience against electronic warfare and GPS spoofing, supporting the Hellenic Armed Forces in critical operations.
Greece is one of the most seismically active regions in Europe. Monitoring the structural integrity of historical monuments, bridges (such as the Rion-Antirrion Bridge), and modern tunnels requires continuous, high-sensitivity acceleration and inclination tracking. Our MEMS accelerometers deliver ultra-low noise performance, enabling real-time structural health monitoring and early warning systems.
The Greek industrial ecosystem is shifting towards digital transformation and green shipping. These major changes demand next-generation Inertial Measurement Systems that offer:
By controlling the complete R&D and manufacturing pipeline, we deliver superior cost efficiency and performance stability.
Reducing production costs by up to 25% through in-house component engineering.
Improving system navigation performance by 20% using advanced sensor fusion algorithms.
Ensuring stable quality and manufacturing efficiency for large-scale industrial orders.
Delivering cross-industry solutions from discrete components to full turn-key navigation systems.
