Filed: 2020-07-16
Abstract: The present invention relates to designing the orbit of satellites and, more specifically, to increasing observation chances and reducing the cost of operating a satellite constellation by an orbit design method for optimizing the revisit cycles of a plurality of satellites for a specific area. To this end, a method for designing the orbit of a satellite constellation includes a design method for setting a starting point of satellite duty by matching intersecting points of the specific area and a satellite orbit, and a program thereof. The program comprises the steps of: receiving the latitude and longitude and the orbital frequency and inclination angle of satellites for a specific area and calculating an initial mean anomaly and an ascending node; and compensating the inclination angle to match the intersecting point of the specific area by using a satellite orbit parameter-type equation of motion. The step of compensating the inclination angle follows fixed-point iteration in conjunction with Fast and Robust Self-intersections, which is the powerful program built into MATLAB. Accordingly, compared with the existing Walker-Delta satellite arrangement technique, the method can dramatically shorten the revisit cycles for the specific area, thereby optimizing increase of observation chances and reduction of the cost of operating the satellite constellation.
