The present invention provides a system for correcting a GPS position in that a GPS datum is corrected by determining the displacement resulting from vibrations and dynamic loads measured at a GPS positioning device attached to a structure such as a high-rise building, a bridge, a dam, a port and so forth. More particularly, the present invention relates to the system for correcting a GPS position by system state estimation, in which vibrations are measured via an input 3-axis accelerometer and an output accelerometer when surveying the structure, and the data is processed in real time with state equations preset using transfer functions with the input acceleration data and output accelerating datum measured on the two accelerometers, and then the modeling is updated with a model update algorithm such that the GPS data-converged values and real values are converged. Thus more accurate GPS position data is calculated, the data processing speed can be shortened by real-time data processing ...
