Indoor Path Planning for Multiple Unmanned Aerial Vehicles via Curriculum Learning
Jongmin Park, Kwansik Park
Multi-agent reinforcement learning was performed in this study for indoor path planning of two unmanned aerial vehicles (UAVs). Each UAV performed the task of moving as fast as pos…
Machine Learning-Based GPS Multipath Detection Method Using Dual Antennas
Sanghyun Kim, Jungyun Byun, Kwansik Park
In urban areas, global navigation satellite system (GNSS) signals are often reflected or blocked by buildings, thus resulting in large positioning errors. In this study, we propose…
GPS Multipath Detection Based on Carrier-to-Noise-Density Ratio Measurements from a Dual-Polarized Antenna
Sanghyun Kim, Halim Lee, Kwansik Park
In this study, the global positioning system (GPS) multipath detection was performed based on the carrier-to-noise-density ratio, C/N0, measured through a dual-polarized antenna. A…
Single-Antenna-Based GPS Antijamming Method Exploiting Polarization Diversity
Kwansik Park, Jiwon Seo
The vulnerability of Global Positioning System (GPS) receivers to jammers is a major concern owing to the extremely weak received signal power of GPS. Researches have been conducte…
Effects of Initial Attitude Estimation Errors on Loosely Coupled Smartphone GPS/IMU Integration System
Kwansik Park, Woohyun Kim, Jiwon Seo
Global Positioning System (GPS) and inertial measurement unit (IMU) sensors are commonly integrated using the extended Kalman filter (EKF), for achieving better navigation performa…
