Low-Cost GNSS Simulators with Wireless Clock Synchronization for Indoor Positioning
Woohyun Kim, Jiwon Seo
In regions where global navigation satellite systems (GNSS) signals are unavailable, such as underground areas and tunnels, GNSS simulators can be deployed for transmitting simulat…
Machine-Learning-Based Classification of GPS Signal Reception Conditions Using a Dual-Polarized Antenna in Urban Areas
Sanghyun Kim, Jiwon Seo
In urban areas, dense buildings frequently block and reflect global positioning system (GPS) signals, resulting in the reception of a few visible satellites with many multipath sig…
Performance Comparison of Numerical Optimization Algorithms for RSS-TOA-Based Target Localization
Halim Lee, Jiwon Seo
The maximum likelihood (ML) estimator can be applied to localize a target mobile device using the RSS and TOA. However, the ML estimator for the RSS-TOA-based target localization p…
Performance Evaluation and Hybrid Application of the Greedy and Predictive UAV Trajectory Optimization Methods for Localizing a Target Mobile Device
Halim Lee, Jiwon Seo
This study investigates unmanned aerial vehicle (UAV) trajectory planning strategies for localizing a target mobile device in emergency situations. The global navigation satellite…
