Based on the basic theory of Earth gravity field recovery using dynamical method,the influence of satellite initial state errors on Earth gravity field recovery with LEO satellite precise orbit data is analyzed in this paper.

The simulation results show that the temporal performances of the longitudinal and distance errors which come from the initial alignment errors are periodically variational.

An approach of the iterative learning control for linear continuous system with the initial error;

Study on the regularity of predictability limit of chaotic systems with different initial errors;

Then,the effect of initial errors for telemetric data and exterior data are minutely induced,and a linear separation model of initial launched parameter errors for wars.
