| Abstract: | The concept of the surrounding-earth-gliding flight is described.In order to approximately compute the corresponding geographical coverage positions,a method of combining the well-known ellipse orbit theory and the n-section constant angle algorithm of gliding inclination was proposed.According to the approximate formula,the analyses indicate that the initial release azimuth angle is an important factor to determine the geographical coverage positions in flight.The results show that the method is effective and feasible. |
