Model-Based GNC
Model-driven guidance, navigation, and control for aerospace vehicle motion and trajectory regulation.
Welcome! I'm Yongjin Kim.
I am an electrical engineering student pursuing model-based guidance, navigation, and control alongside vision and optical navigation for aerospace systems.
02 / Research
Areas of interest
My interests center on model-based GNC and vision/optical navigation, supported by state estimation, embedded computing, and experimental validation.
Vision / Optical Navigation
Camera-based target detection, relative-motion estimation, and optical-flow tracking for autonomous flight.
03 / Projects
Selected engineering work
Each entry separates implemented work from ongoing development and documented study.
Flight systems
Rocket Avionics and Validation
Built a real-time telemetry GCS verified at approximately 600 m and developing an STM32F405 HILS replay platform for repeatable avionics firmware validation.
Embedded control
IMU-Based Active Suspension
Implemented chassis roll/pitch PD control on an STM32F405 for a four-motor stroller-scale testbed, with Arduino UNO R4 WiFi telemetry and web ON/OFF control. Final firmware, a demonstration video, and the submission report are published; closed-loop performance validation remains ongoing.
FPGA navigation
FPGA-Accelerated Multi-Sensor Navigation
Developing an HLS-based 21-state EKF and an Arty A7-100T architecture to synchronize multi-rate IMU, GNSS, barometer, and magnetometer data.
OngoingNavigation
INS/GNSS Integrated Navigation
Implemented and evaluated a 15-state loosely coupled EKF for UGV trajectory estimation, including position, velocity, and attitude error analysis.

Landing Target Detection and Tracking
Developing real-time landing-target detection and relative motion tracking with C++/OpenCV feature matching and optical flow.
OngoingIndoor localization
UWB/IMU Localization and IoT Monitoring
Developing a Raspberry Pi 4-based localization system with sensor fusion, database logging, and web-based monitoring and control.
OngoingDigital hardware
Tiny Neural Network Accelerator
Implemented FC1-Norm-ReLU-FC2 inference with a reusable 4x4 weight-stationary systolic array, tiled multiplication, and batch-mode control logic.
