QPL certification is a system in which the US government guarantees the quality only for products that have passed strict local company inspections made of 150 tests and verifications under the supervision of the US government. Yeonhab Precision obtained the certification in Asia for the first time after 10 years of application. In particular, with the successful QPL registration for the first time in Asia, Yeonhab Precision is the first and only company in Asia which got the qualification of marking “MS” with the title of “Korea’s first MIL-DTL connector”. We will provide customers with the best products as we have the sense of the pride of developing the QPL certified connector with our own technology in Korea.

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.

Our advanced mine detector combines photochemical and metal detection technologies, enabling the identification of both metallic and non-metallic mines. Selected in December 2024 for the Global Small but Strong Enterprise Development Program by KRIT, this cutting-edge system is now under development. Backed by a Letter of Commitment from Ukraine, it is set to play a key role in reconstruction and humanitarian demining efforts.

It is an UAV recovery system that lands a fixed-wing UAV even in mountainous terrain where there is no sufficient runway for landing. Similar to the arresting hook method used to land an aircraft on an aircraft carrier, the UAV is caught by a pendant and braked, and a net is also added in case of an emergency.

Active phased array fire control radar (AESA) for aircraft A fire control multi-function radar (MFR) that can simultaneously detect, identify, and track multiple targets, including in the air and on the ground, and has SAR and NCTR functions. Aircraft (fighter)-mounted AESA radar is a core sensor for fighter jets to perform day/night/all-weather multiple missions. It operates in multiple modes such as air-to-air/air-to-ground/air-to-sea/support mode, and acquires ground images and air/ground in electronic warfare situations. It is essential mission equipment for fighter jets that detects/tracks multiple targets and supports guided missile guidance and gun shooting.
