000018786 520__ $$2eng$$aThe Global Navigation Satellite System (GNSS) has become an important technology with which to calculate the crustal deformation and displacement waves produced by earthquakes. In Japan, a dense GNSS network (GEONET) is available, with 1200 stations distributed uniformly throughout the country. Currently, relative positioning is one of the most precise GNSS positioning techniques, with a centimeter level of accuracy. However, this method requires two GNSS stations: a station where an estimation of displacement is to be determined and a station that remains stationary with a well-known position. To fulfill this requirement, the base station must be located far enough from the epicenter to assure that no displacement is produced. The performance of relative positioning depends on the distance between the receiver and the base stations, often referred to as the baseline. In this study, we evaluate this tradeoff by calculating the permanent displacement in the Geonet station 0266 during the November 22, 2014 Mw 6.2 Nagano earthquake several times with different base stations. Then, variations in the permanent displacement are evaluated in terms of the baseline. With several available GEONET stations to set as the base station, we study the relationship between the performance of displacement and the baseline.
