Abstract: The field experiments on monitoring land subsidence in large area by GPS-RTK are carried out in different distances and different time intervals. The experiment results are analyzed; and some key parameters about effects of distance and observational duration on precision of monitoring are obtained so as to be helpful in practice of land subsidence monitoring using RTK and in formulating specifications.

Key words: global positioning system(GPS), real time kinematic (RTK), monitoring, land subsidence
