GNSS has been widely used for the mine real-time deformation monitoring which is an important issue for mines.The multiple Kalman filters model with shaping filter was proposed to detect the deformation in real-time and improve its reliability.Two problems solved in this paper: firstly because the GPS real-time deformation series with a high sampling rate contain coloured noise,the multiple Kalman filters model is augmented by a shaping filter in order to reduce the colored noise; secondly the multiple Kalman filters model with shaping filter is used to detect the deformation epoch in real-time in order to improve the quality of GPS measurements for the real-time deformation applications.The different GPS time series are used to verify the effectiveness of the multiple Kalman filters model with shaping filter.
