Realtimewave

What Realtimewave does

Realtimewave (REALTIMEWAVE Co., Ltd.) is a private South Korean defense and aerospace technology company founded in 2002 and headquartered in Pangyo, Seongnam. It develops real-time simulation and testing platforms — primarily the RTNgine product line — used for Hardware-In-the-Loop Simulation (HILS), System Integration Laboratory (SIL), and Software Test Environment (STE) verification of avionics, flight control systems, guided weapons, satellite launchers, and unmanned vehicles. The technology stack combines proprietary real-time operating system expertise with hardware platforms (RN7 series, AeroBox, BirdieBox) supporting military-standard interfaces (MIL-STD-1553B, MIL-STD-1760, ARINC429, AFDX/ARINC664p7, CAN) and a software suite covering the full test lifecycle (ICDSS/ICD Manager for interface control documents, System Bridge for test configuration, Test Automation for requirement-based testing, RDSS for data monitoring, MachATE for test scenario generation). The company was established to localize HILS/SIL equipment core software that Korea had previously imported from overseas, with all source code developed in-house since inception.

The company makes money through three streams: (1) one-time software licenses for RTNgine and the surrounding tool suite, (2) hardware sales of real-time simulation computers and interface modules, and (3) professional services for system integration and complete HILS/SIL/test equipment delivery. Go-to-market is direct enterprise sales targeting Korean defense agencies (the Defense Agency for Science and Technology/ADD), prime contractors (Korea Aerospace Industries/KAI on the KF-21 program), and government aerospace programs (K-UAM OPPAV), supplemented by conference participation at events such as Seoul ADEX, KORMARINE, AEROTEC, and ASSK. Pricing is quote-based and not publicly disclosed. The company has remained private and founder-led, with CEO Ha Kyung-tak (하경택) at the helm since founding, and has grown organically from 5 to 57 employees without disclosed external funding rounds. Strategic posture has shifted in 2025-2026 toward AI-native test capabilities (April 2025 AI platform launch), Linux-based deployment (March 2025 Linux RTNgine), distribution partnerships (Green Hills Software in 2026), and international event presence.

Realtimewave's products have been deployed in 80+ projects since 2009 including KF-21 flight control HILS and radar interface OFP development, LAH avionics and armament SIL, LCH avionics SIL, KSLV II satellite launcher SIL, MUM-T integration testing, and Korean CUAV/MUAV systems. Recent certification milestones include SP (Software Process) Level 2 — equivalent to CMMI Level 3 — obtained in 2023, and ISO 9001:2008 in defense/aircraft simulation since 2010. The company also maintains a Daedeok (Daejeon) integration and testing center and a Sachun branch office alongside the Pangyo headquarters.
