Abstract: We first study through both theoretical and experimental investigations the tropospheric effect on GPS applications in monitoring high-rise buildings when the height difference between the reference and the rover stations are large. Various methods for modeling and correcting the tropospheric effect on such GPS applications are then investigated. The Saastamoinen model and ground meteorological data are first used to calculate the tropospheric delays. A Kalman filter model is then used to estimate the tropospheric zenith delays in GPS solutions. Finally, we use such information as known building height as constraints in GPS solutions. The performances of these methods are evaluated using a data set obtained in monitoring a building that is over 200 m tall. The SIGMA-ε GPS stochastic model is also used in combination with the various methods to reduce the effects of the various noise.
