Explore our leading-edge lightweight navigation, acoustic positioning, and attitude heading reference systems engineered for rigorous environments.
South Korea has rapidly emerged as a global powerhouse in advanced aerospace, defense, and maritime engineering. Driven by national initiatives such as the development of indigenous fighter jets (like the KAI KF-21 Boramae), military helicopters, and the booming Urban Air Mobility (UAM) sector, the demand for highly reliable Air Data Reference Systems (ADRS) and Air Data Computers (ADC) has surged. An Air Data Reference System plays a critical role in modern aviation by measuring key aerodynamic parameters—including static and total pressure, angle of attack, airspeed, and air temperature—allowing onboard flight control computers to execute precise maneuvers safely.
As South Korean aerospace giants like Korea Aerospace Industries (KAI) and Hanwha Aerospace expand their global footprint, local defense acquisitions and commercial aviation projects require flexible, high-precision ODM (Original Design Manufacturer) partners. Our factory specializes in delivering custom ADRS architectures that integrate seamlessly with local South Korean specifications, ensuring compliance with strict military and civil aviation safety standards. By bridging advanced sensor fusion with cost-efficient manufacturing, we serve as a premier supplier for South Korean research institutes and commercial enterprises alike.
Strategic Local Application: South Korea's rugged topography, coupled with complex coastal weather patterns along the Yellow Sea and East Sea, demands air data systems that feature advanced thermal calibration, high vibration resistance, and zero-drift operational stability.
The South Korean Ministry of Land, Infrastructure and Transport (MOLIT) is aggressively promoting the "K-UAM" (Korea Urban Air Mobility) roadmap, aiming to commercialize urban air passenger services. Autonomous air taxis and cargo drones operating over densely populated metropolitan areas like Seoul and Incheon require redundant, lightweight, and highly integrated Air Data Reference Systems. Unlike traditional commercial aircraft, UAM vehicles operate at lower altitudes where wind shear, urban micro-climates, and thermal updrafts present significant flight control challenges. A robust ADRS, combined with MEMS-based Attitude and Heading Reference Systems (AHRS), provides the high-frequency measurements necessary to stabilize these vehicles in real-time.
Furthermore, South Korea's defense posture requires rapid deployments of Unmanned Aerial Vehicles (UAVs) for surveillance and reconnaissance. In GPS-denied environments—a common challenge near the Demilitarized Zone (DMZ)—inertial navigation coupled with precise air data calculation becomes the primary method to maintain flight path integrity. Our ODM design philosophy focuses on miniaturization and multi-sensor integration, combining FOG (Fiber Optic Gyroscope) or MEMS inertial sensors directly with air data sensors to provide a complete, jam-resistant navigation suite.

Poseidon International Limited, Hong Kong strives to provide satisfactory products and services to customers from all walks of life.
Demonstrating our R&D capabilities and systems integration in specialized fields across South Korea and East Asia.
We specialize in the independent research, design, and production of fiber optic gyroscopes (FOG), inertial navigation systems (INS), attitude and control systems, autonomous driving systems, and intelligent control systems for unmanned equipment. By integrating industry-specific requirements, we have made significant technological advancements in digitalization, automation, and intelligence, securing multiple technical patents. With years of experience, we have evolved into a multi-industry intelligent solutions provider with a portfolio of proprietary core technologies.
Our core team comprises seasoned experts with extensive backgrounds in aerospace and inertial navigation. We have successfully tackled critical technological challenges in high-precision GNSS-free navigation, laser measurement, integrated navigation, multi-source data fusion, and precise positioning—areas that were once bottlenecks in the industry.
Our products are smaller in size, higher in accuracy, and more stable in performance, featuring long-term dynamic auto-calibration with zero-drift operation. They are widely adopted in scientific research, industrial control, intelligent unmanned systems, high-precision detection, and metrology. Having passed rigorous validation in aviation, aerospace, marine, mining, and railway applications, our solutions have been procured in bulk, filling key technological gaps in China and East Asia.
We operate over 6,000-square-meter manufacturing facility in mainland China, equipped with advanced R&D, production, and testing infrastructure, enabling large-scale production and timely delivery. Our network of subsidiaries, offices, and spare parts warehouses across China ensures prompt technical support and after-sales service.
Compared to similar companies, we offer unique advantages that align with South Korea's high-tech procurement standards.
Beyond traditional aerospace, our integrated navigation systems serve vital sectors within South Korea’s maritime economy. South Korea is home to some of the world's largest shipyards in Ulsan and Geoje, alongside massive smart port automation initiatives in Busan. These industrial environments require precision positioning systems that remain unaffected by satellite jamming or complex steel structures that distort magnetic fields. Our lightweight MEMS and FOG navigation systems are extensively deployed on Autonomous Underwater Vehicles (AUVs) and Remotely Operated Vehicles (ROVs) searching for sub-sea natural resources or inspecting offshore wind turbine foundations off the coast of Jeju Island.
By offering customized OEM modifications, we can adapt the communication protocols of our acoustic positioning and attitude heading sensors to integrate smoothly with South Korean industrial automation standards. This flexibility allows local marine engineering firms to deploy advanced diver safety positioning systems, ensuring that personnel operating in deep waters have reliable real-time tracking and emergency communication links back to support vessels.
South Korean research institutions, such as the Korea Aerospace Research Institute (KARI) and the Agency for Defense Development (ADD), maintain exceptionally high standards for hardware reliability. When sourcing ODM Air Data Reference Systems and Inertial Navigation Systems, these organizations prioritize environmental stress screening (ESS), electromagnetic compatibility (EMC) testing, and comprehensive calibration reports. Our manufacturing facilities are equipped to provide full-temperature testing (from -40°C to +85°C) and dynamic calibration, ensuring that every sensor delivered to South Korea meets or exceeds the specified operational limits.
Whether you are developing next-generation tactical missiles, tactical UAVs, autonomous marine vessels, or high-altitude weather monitoring platforms, our engineering team is prepared to collaborate closely on custom hardware form factors, sensor ranges, and software interfaces. We provide comprehensive documentation, SDKs, and engineering support to accelerate your system integration timeline.
