The comparison and analysis of the parameter estimation methods for tropospheric refraction on GPS precise positioning.
Abstract
Some parameter estimation methods to correct the wet zenith delay, including single parameter, multiple constant parameter and piecewise linear estimation manners, are compared one another through direct comparison of the estimated parameter values and the effects of these various methods on relative positioning with the observation data from the 15 stations during the Chinese GPS'94 campaign.
