Method for calculating flying arrival moment and shooting range of satellite

The invention discloses a method for calculating the flying arrival moment and the shooting range of a satellite, and the method comprises the steps: taking the first-row data as a satellite name according to the structure of a satellite ephemeris; storing satellite related data in the last two rows, used for determining the number of orbits of the space target running around the ground at the given epoch moment; calculating the specific position of the satellite on the orbit by using the data according to the first-order time derivative of the first-line average motion of the two lines of elements; the second-order time derivative of the average motion being used for calculating the orbital displacement caused by the change of the average motion of each day, and the parameter being used for predicting the on-orbit position of the satellite, so that the flying arrival moment simulation can be carried out; calculating the orbit period and the major semi-axis according to the relationship between the running pe
