Abstract:

A method is given for improving the orbital elements of artificial satellites when the observation times are only approximately known. Corresponding conditional equations are derived, one of which is independent of time error. It is shown that some orbital elements can be determined from the equations which are independent of time errors, and the optimum conditio s for determining these elements are analyzed. Conditional equations are given for corrections in the absolute coordinates of observational stations, and these equations are analyzed. An example is given using this method for improving the orbital elements of artificial satellites. Author
