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.

Lumir, in collaboration with the Electronics and Telecommunications Research Institute (ETRI), developed and integrated this device for lunar exploration aboard Danuri (KPLO, the Korea Pathfinder Lunar Orbiter), Korea's first lunar probe. This device successfully demonstrated its performance by receiving BTS music videos transmitted from the Moon to Earth, achieving Technology Readiness Level (TRL) 9.

The HXB13 Connectors, featuring expanded beam technology, hermaphroditic connection, rugged construction for field deployment have been designed for harsh environment applications such as military tactical communications, avionics, offshore systems, outside broadcast, mining and plant.

The expanded beam technology uses expanded and collimated beams to couple optical fibers without any contact. It could allow for optics to be used in areas that have been quite restrictive due to presence of damage or contamination at the fiber end. Hermaphroditic connector design enables fast deployment by daisy-chaining multiple cable segments.

FEATURES
· Advanced expanded beam technology
· Rugged field deployable fiber optic connector
· Hermaphroditic interconnection
· 2 to 4 Optical Channels for Singlemode or Multimode
· Custom configurations available
· Environmental sealing (IPX8)
· Very high resistance to vibration, shock, environmental effects, dust, and debris

Safran’s TG600 is a 600 kW hybrid-electric turbogenerator—derived from the Arrano turboshaft and paired with GENeUS generators—designed to serve as the core propulsion component for Electra’s nine‑passenger eSTOL aircraft.

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.

Portable thermal target with day/night combined shooting training. Application of advanced thermal sensing technology to realistically reproduce various combat situations to improve the user's shooting ability. Heat generation performance can be achieved through multiple fires, increasing shooting training efficiency and reducing operational costs.

DIVE (Digital Interactive Virtual Environment) is a GIS-based smart construction management platform jointly developed by ZYX Technology and Korea Expressway Corporation. Designed to meet the growing demand for intelligent infrastructure solutions, DIVE provides real-time integration, monitoring, and analysis of all location-based construction data. By consolidating diverse sources such as design drawings, land maps, aerial imagery, BIM data, drone footage, and CCTV into a single platform, DIVE enables comprehensive, on-site visibility and control. From large-scale infrastructure to complex tunnel projects, all key information can be accessed and compared in real time, allowing for smarter, faster, and more accurate decision-making. The main dashboard provides a live overview of each project site, including tasks, equipment, workers, events, and safety issues. With its daily work management feature, site managers can view exact personnel and equipment allocations for each zone, improving efficiency and minimizing risk. DIVE also supports seamless integration with tunnel monitoring systems, offering real-time access to excavation status, geotechnical sensors, and worker presence inside the tunnel. This ensures enhanced safety and process transparency in high-risk environments. Drone integration further strengthens site management by providing up-to-date aerial visuals, reducing blind spots and enabling rapid response to field changes. In addition, the platform links design drawings with cadastral maps to streamline permitting, track construction progress, and manage change orders with geographic accuracy. Whether you're building roads, tunnels, or complex infrastructure, DIVE empowers construction teams with a powerful digital environment to manage the entire project lifecycle.
