Our extensive design capabilities enable us to produce the most sophisticated technological units known in the Aircraft Ground Support Equipment (AGSE) profession.

It is a product lineup that is proven in global markets and has world-class competitiveness. And it is being exported to more than 20 countries around the world.

FOSTEC optical fiber pin/socket terminals are designed to connect to each other through physical contact. POSTECH's unique alignment technology maximizes optical performance and provides reliability.

We carry a wide range of aerospace-grade materials in round bar and sheet, including: -Alloy 718 (AMS5596) -Alloy 625 (AMS5599) -Alloy X (AMS5536) There is no minimum order quantity ? we can cut from a single piece and ship within 1?2 days, complete with full material traceability. For non-stock grades, shapes, and standards, we can source materials from suppliers worldwide with a lead time of approximately 2 weeks, also with no minimum order quantity.

The Bombardier Global 6500 aircraft is the go-to choice for the most demanding specialized missions around the world. Governments, militaries and operators choose this aircraft for its ideal combination of performance, reliability and flexibility, and because it is highly adaptable to outer mold line (OML) manipulation. The Global 6500 aircraft has class-leading power for mission equipment, over 18 hours of endurance, advantageous maintenance intervals and ample cabin space for workstations, patient transport and mission equipment.

Developed as Korea’s first hydrogen-and-battery hybrid propulsion system, this next-generation eco-friendly aircraft uses electric batteries for take-off and hydrogen fuel cells for cruise flight, achieving a new standard in sustainable aviation. Recognized as a world-first intellectual property, this model also became the first hydrogen hybrid Advanced Air Mobility (AAM) aircraft in Korea to receive Special Airworthiness Certification from the Ministry of Land, Infrastructure and Transport in 2024.

The 20W X-band BUC is a satellite ground transport terminal that includes a receive rejection filter and performs IF-to-X-band upconversion using an internal reference frequency. It features dustproof, moisture-proof, and waterproof protection, along with self-diagnostic functions such as fan and temperature alarms. The unit provides a total gain of over 50 dB and supports a wide bandwidth of 500 MHz. Its frequency stability is maintained within 0.35 ppm.

T/FA-50 PTO Shaft, The New Standard for Next-Generation High-Speed Rotating Power Transmission The power transmission shaft (PTO Shaft) applied to the T/FA-50 features in-house designed, optimized flexible couplings that provide excellent durability. In addition, the adoption of high-speed precision balancing technology effectively suppresses vibration and ensures shaft oscillation prevention. While it shares a similar form with the KF-21 power transmission shaft, the T/FA-50 PTO Shaft incorporates unique, dedicated technology, making it distinct. The system development has been completed, and performance improvements are continuously underway with the goal of localization.
