ORSKOREA’s high frequency grinding spindles, operating at speeds up to 120,000 rpm—the highest level in Korea—are engineered for ultra-precision and durability in critical defense and aerospace applications. In addition to belt-driven, built-in motor, hydrostatic, and hydrodynamic types widely used in semiconductor and precision equipment, our spindles are customized to deliver the exact speed and power output required by customers. With over 25 years of expertise in repairing and retrofitting leading Japanese, German, and Swiss brands such as TOYO, KOYO, OKUMA, GMN, and Fischer, and with multiple proprietary patents including joint developments with Schaeffler Korea, ORSKOREA ensures proven reliability. These spindles are ideal for machining high-value defense components such as armored vehicle gears, drone actuators, aircraft engine parts, multispectral sensor housings, and advanced optical or communication devices, supporting the competitiveness of both defense and civilian manufacturers.

The ACTUS® CORE-5 is the latest development of our Dot Sight lineup. It delivers the same high-end optical performance and legendary durability as our existing CORE Dot Sights, now with enhanced features based on feedback from professional users. The ACTUS® CORE-5 offers three reticle designs and improved ergonomics, with relocated illumination controls on the top for ambidextrous operation—ensuring seamless adjustments while staying clear of chest rigs and plate carriers when slung. A dedicated night vision override switch allows for instant adaptation to sudden lighting changes, while the CR2032 battery provides an impressive 20,000-hour runtime at Level 8 brightness.

· Optimized deployment of manned and unmanned aerial assets with separate takeoff and landing runways · Securing aerial/maritime superiority with unmanned combat aerial vehicles (UCAVs) and Drone · Expanded real-time surveillance range through the operation of medium-altitude unmanned reconnaissance aerial vehicles · Enhanced assault capabilities to target and command & control (C2) with manned and unmanned forces

The EPNR4000 is a vehicle-mounted 5G base station integrating CU-DU-RU, offering wider service coverage than the EPNR2000. It connects to a separately installed 5G Core and IP-PTT application server in the vehicle, providing 5G services, making it an ideal system for use in disaster situations or military operations.

Leveraging industry’s leading MEMS technology to provide previously unheard of capabilities in angle random walk values (0.02°/√hr.) without loss of tactical grade levels across military environments, including 1°/hr. bias stability, the SDI500 is designed to achieve the demanding performance levels required in sophisticated systems applications. It is particularly suited for use by Integrators and OEMs, packaged in a highly miniaturized, cylindrical configuration with a volume of only 19 cubic inches. Boasting a 20-Year lifetime capability without requiring calibration and a MTBF of more than 100,000 hours, multiple output data formats and SDLC, RS232 and UART output interfaces are provided in this revolutionary IMU for optimized systems protocols.

- To measure RCS for the aircrafts, warships, helicopters, chaff and etc. - Verify to meet pre-defined RCS specifications on design phase.

A distributed sensor system based on BOTDA (Brillouin Optical Time Domain Analyzer), capable of detecting structural deformation and external intrusion.

Developed and manufactured by MPS Microsystems based on customer specifications, this lens actuator forms an essential component of a laser guidance system for unmanned flying objects. It enables 2 lens groups to be displaced individually over a total range of 48 mm and makes it possible to focus a laser over a distance of several kilometres. The main technical difficulty inherent to this actuator lies in meeting very stringent requirements for alignment between the two lens groups (< 10 µm) and in maintaining a very small tilt of the lenses over their entire stroke (lateral deviation < 2 µm). The key part making it possible to ensure such specifications is a frame machined by milling from an aluminium block, into which the 2 drive systems are fastened. These systems each consist of a Ø16 mm brushless motor and a Ø4 mm ball screw with an axial play of less than 5 µm. Backlash-free and frictionless sliding of the lens holders is ensured by standard L306 linear ball bearings manufactured by MPS Microsystems.
