What J.MARPLE does
J.MARPLE (주제이마플) is a privately held Korean drone technology company headquartered in Seochogu, Seoul, that builds positioning, navigation, and communication subsystems for unmanned aircraft operating in environments where GPS is unavailable, denied, or unreliable. Its portfolio addresses three interlocking technical problems: GPS-free positioning via the Visual Positioning System (V-GPS), which matches onboard camera imagery against satellite maps; LiDAR-based localization and mapping through the SLAMBOX embedded board, which integrates with sensors from Ouster, Livox, Unitree, Velodyne, and SOSLAB and outputs MAVLink-compatible data for PX4 and ArduPilot; and coordinated multi-device communication via J.Fi, a 2.4GHz wireless module supporting 1:1, 1:N, and N:N topologies with time-slot-based collision management. Supporting products include the Precision Landing Support System for vision-based autonomous landing on moving platforms, the Airhart II Pixhawk-compatible flight controller with an Analog Devices ADIS16477 IMU, a Jetson Nano/NX carrier board for embedded compute, the J.JIG and original Drone Jig ground-testing equipment, and the SALIM X coaxial drone platform designed for GPS-denied and dark-environment flight.
The company's customer base spans industrial and commercial drone operators (infrastructure inspection, warehouse automation, tunnel/mine exploration), emergency response and search-and-rescue teams, drone manufacturers and R&D testing facilities, and Korean government and UAM ecosystem participants. Revenue is generated primarily through hardware sales distributed via the company's own Naver SmartStore, the Korean electronics retailer DeviceMart, and direct inquiry-based sales for enterprise and international customers, supplemented by professional-services revenue from a Korean government contract to design and validate the data exchange system for the K-UAM (Korean Urban Air Mobility) traffic management ecosystem. Go-to-market leans heavily on industry events such as Drone Show Korea and the Unmanned System World Congress, alongside content marketing through the company website and YouTube demonstration videos.
J.MARPLE was established prior to 2021 (founding date not publicly disclosed) and has demonstrated technical progression through more than a dozen documented milestones since April 2021, including continuous flight testing of V-GPS at Eoseom Airfield, the SALIM X coaxial drone unveiling in April 2024, and the J.Fi launch in February 2025. The company is led by CEO Kim Seong-pil (김성필) and operates without disclosed institutional investment, suggesting a founder-financed operating model at sub-scale relative to the addressable market it targets.
