•Improved PPP is used in kinematic model for oscillating displacement monitoring.•The improved PPP has better convergence performance with high cut off angle.•Better accuracy can be achieved by ZWD augmented PPP in kinematic model. This paper developed the tropospheric correction augmented PPP for t...
