We, STX Engine, started with our business to be designated as a defense company in 1977 and established a factory for defense purposes in 1988. Moreover, we have grown into a largest defense diesel engine manufacturer by licensing with MTU. Based on the aforementioned fact, we manufacture and provide diesel engines for main battle tank, self-propelled artillery and armored vehicle to ROK Army, for destroyer, frigate, patrol vessel and support vessel to ROK Navy, for patrol vessel to Korea Coast Guard as well.

Our XR-based aircraft maintenance simulator is officially certified by the Ministry of Land, Infrastructure and Transport (MOLIT) of South Korea for training and education. It provides specialized training environments for the A321, B737-MAX, and B737-800NG aircraft, featuring over 80 detailed modules—including procedures for engine removal, main landing gear installation, and more. This subscription-based simulator is fully compatible with smartphones, tablets, and wearable XR devices, enabling seamless access through a cloud-based web service. Users can train anytime, anywhere—perfect for both remote learning and remote maintenance scenarios. Compared to traditional classroom learning, the XR platform is 4 times more effective and requires only one-third the training time. It also improves user confidence in real-world technical applications by up to 275%. By transforming traditional paper manuals into immersive, interactive training environments, the simulator delivers the next generation of aircraft MRO education for both civil and defense sectors.

AI Navigation Algorithm The Certus Mini range features Advanced Navigation’s revolutionary AI neural network sensor fusion algorithm. The algorithm was designed for control applications and has a high level of health monitoring and instability prevention to ensure stable and reliable data. High-Performance MEMS The Certus Mini range contains high performance MEMS sensors that are put through Advanced Navigation’s intensive 8 hour temperature calibration process. This provides the highest accuracy possible from this sensor class and outputs consistent accuracy over the full temperature range from -40°C to 85°C. Reliability The Certus Mini range has been designed from the ground up for mission-critical control applications where reliability is essential. Built using a safety-oriented real-time operating system, all software is designed and tested to high safety standards with fault-tolerance in mind. The Certus Mini range is designed, manufactured and tested to military standards. L1/L5 Multi Constellation RTK GNSS The Certus Mini N supports L1/L5 dual frequencies, and GPS, GLONASS, Galileo, BeiDou and NavIC constellations. Access to multiple constellations and frequencies provides enhanced accuracy, availability and performance even in difficult environments such as multi-storey urban canyons. The GNSS receiver has 10 mm position accuracy with real-time RTK or post-processed PPK. Extensive Interoperability Certus Mini seamlessly communicates with a wide range of industry standard protocols including NMEA 0183 and CANOpen making it easy to integrate into existing systems. Certus Mini effortlessly interfaces with ROS 1, ROS 2, and Ardupilot, streamlining your development processes for maximum efficiency and effectiveness.
