RESEARCH IN PRACTICE

From hardware to software,
turning research into systems.

Research and development experience gained through work commissioned by the Korea Railroad Research Institute.

2023
Positioning device prototype fabrication
We fabricated prototypes of UWB tag and anchor terminals for railway applications.
2024
Positioning server and operational interface development
We developed a train positioning server, APIs for using the data and a map-linked management interface.
2025
Sensor-fusion positioning system enhancement
We enhanced UWB·IMU sensor fusion and position estimation algorithms, and conducted integration tests on a reduced-scale train.

SYSTEM COMPONENTS

Measuring positions,
making the data usable.

01 / TAG

Onboard UWB·IMU tag

We integrate positioning devices mounted on vehicles with inertial sensor information.

02 / ANCHOR

Trackside UWB anchor

Installed along the track, anchors support the measurements needed to estimate tag positions.

03 / FUSION

Sensor fusion algorithm

We combine UWB and inertial sensor information to estimate position trajectories.

04 / SERVER

Positioning server and management interface

We collect and process position data and connect it to APIs and map-based interfaces.

Reduced-scale train PoC validation

We conducted integration tests and position tracking with tags, anchors and the positioning server. Based on this research validation experience, we assess project-specific application conditions and product development.

NEXT APPLICATION

From research results to field application.

Development capabilities: Positioning devices · sensor fusion · server·API · map-linked UI
Field application assessment: Installation environment · radio conditions · vehicle interfaces · test scope
Further research directions: Multi-sensor precise stopping support · integration of onboard communications and positioning data · use of operational information

Based on reduced-scale train PoC experience, we assess application and product development suited to vehicle and track environments. Project-specific performance, safety and certification requirements are considered together with the application scope.
