Abstract: Making the use of the fact that the rate of the direction observation can be obtained with aid of the information of concentrated data of the direction observation, in this paper a new method of improving the orbit determination, is presented, which can set up the conditional equations of both the direction observation and its rate simultaneously, and calculate their weighting coefficients as well. The method is believed to be useful for some practical and routine work to improve the accuracy of the orbit determination.
