NavLeader (GPS GNSS Surveying)

Yong-Won Ahn holds a BS.c in the department of Astronomy and Space Science at Chungbuk National University in South Korea. He also holds an M.Sc.E from the Department of Geomatics Engineering at the University of Calgary (UofC) obtained in 2005. He is currently a Ph.D candidate and has been appointed as an instructor from 2008 to now in the Department of Geodesy and Geomatics Engineering at the University of New Brunswick (UNB), co-supervised by Prof.Dare and Dr.Kim. He has actively involved in GNSS (global navigation satellite system) research from Space Geodesy Division at Korea Astronomy and Space Science Institute (KASI, currently one of IGS (international GNSS service) data centres) since 1996 in several different areas as a research staff. He also involved in the telemetry data analysis for KomSat, the first Korea communication satellite, at Korea Aerospace Research Institute (KARI) in 1996.

His previous research areas include in geodynamics (neotectonics), telemetry data analysis, SLR (satellite laser ranging), orbit determination of LEO satellite using Cowell, Encke, VOP (variation of parameters), Kozai's method. In addition to them, he also involved in the research of earthquake analysis, auto-artillery system using GNSS, prediction of gas pipe displacement.

His main research focus from 2002 includes in the tropospheric delay estimation with GNSS observables, radiosonde data, the ray-tracing technique using numerical weather prediction model (NWP, e.g. NOAA RUC20), and atmospheric and space-borne simulation by SPRINT's GNSS hardware simulators. His current goal is to mitigate the tropospheric anomaly effect on GNSS in order to get a reliable position solution with his own developing platform, enhanced RTK positioning software written by C++, and Matlab.

His officially managed site is http://kepler.gge.unb.ca (SuomiNet SA56). Instruments managed are SPIRENT's STR4760 GNSS hardware simulator (dual chassis), lots of high precision GNSS receivers, antennae, 3D motion table for attitude determination, Paroscientific Met4A-1, Radimetric water vapor radiometer WVR-1100, and etc.
