Abstract
To solve the accuracy deficiency of simulation operational software for the track computation of a certain type of UAV, this paper proposes a novel track computation approach based on the positive and negative solution formula of ellipse. According to geodetic coordinate system and the geodetic datum related principles, the off-course track of UAV is calculated by using the micro-element analytic method, and the longitude and latitude of flying UAV in the state of a small off-course angle and the constant altitude are calculated by reducing the time interval. Test results indicate that the track of UAV under the circumstance of a small off-course angle can be calculated accurately by using this algorithm, and the track be corrected for some special cases when the UAV flying over the maximum point and/or equator, which can be also available for the off-course track computation of other air vehicles.关键词
