First Demonstration of the Korean eLoran Accuracy in a Narrow Waterway Using Improved ASF Maps
Woohyun Kim, Pyo-Woong Son, Sul Gee Park +2
The vulnerabilities of global navigation satellite systems (GNSSs) to radio frequency jamming and spoofing have attracted significant research attention. In particular, the large-s…
Enhanced Accuracy Simulator for a Future Korean Nationwide eLoran System
Joon Hyo Rhee, Sanghyun Kim, Pyo-Woong Son +1
The Global Positioning System (GPS) has become the most widely used positioning, navigation, and timing system. However, the vulnerability of GPS to radio frequency interference ha…
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…
Integrity-Based Path Planning Strategy for Urban Autonomous Vehicular Navigation Using GPS and Cellular Signals
Halim Lee, Jiwon Seo, Zaher M. Kassas
An integrity-based path planning strategy for autonomous ground vehicle (AGV) navigation in urban environments is developed. The vehicle is assumed to navigate by utilizing cellula…
RSS-based LTE Base Station Localization Using Single Receiver in Environment with Unknown Path-Loss Exponent
Suhui Jeong, Halim Lee, Taewon Kang +1
With the increasing demand for location-based services, localization technology research has recently intensified. Received signal strength (RSS)-based localization has the advanta…
A Preliminary Study of Machine-Learning-Based Ranging with LTE Channel Impulse Response in Multipath Environment
Halim Lee, Jiwon Seo
Alternative navigation technology to global navigation satellite systems (GNSSs) is required for unmanned ground vehicles (UGVs) in multipath environments (such as urban areas). In…
