Embodiment 1

[0050] Embodiment one: if figure 1 As shown, a method for aircraft track simulation, including:

[0051] Step 1: The radius of the arc DE is the semi-minor axis b of the ellipsoid, the radius of the arc FG is the semi-major axis a of the ellipsoid, and the arc DG of the ellipse is a part of the longitude line of the ellipsoid. Point K is the projection point of the aircraft on the ellipsoid, the longitude coordinate is L, the latitude coordinate is B, draw a vertical line from K point to the coordinate axis, and the intersection points are C and M. Point K1 is the intersection of the extension line of CK and the arc FG. kT is a tangent, and KN is perpendicular to KT.

[0052] Step 1: According to the parametric equation of the ellipse:

[0053] (1)

[0054] From the formula (1) can get: (2)

[0055] Step 2: by figure 1 It can be seen that KT is the tangent line of point K on the ellipse, and its slope is formula (3),

[0056] (3)

[0057] Step 3: Get formula (4) ...

Abstract

The invention relates to the field of navigation management, in particular to a method for simulating aircraft flight tracks. Aiming at the problems existing in the prior art, the method for simulating the aircraft flight tracks enables the accurate aircraft flight tracks to be simulated flexibly according to the information such as the current location of an aircraft and the speed of the aircraft. According to the method for simulating the aircraft flight tracks, the longitude L2 and the latitude B2 of the position where the aircraft located after unit time t is obtained according to the longitude L and the latitude B of a projection point K of the aircraft on a spheroid and the component velocity VL on the circle of longitude and the component velocity VB on the circle of latitude of the aircraft, and then a series of the flight tracks of the aircraft are obtained.

Description

technical field [0001] The invention relates to the field of air traffic management, in particular to a method for simulating an aircraft track. Background technique [0002] In the field of air traffic control, the flight status report of the aircraft's air position, altitude, speed, etc. is an important detection content in this field. Accurate and real-time monitoring of flight conditions is an important development direction of air traffic control monitoring in the future. The research experiment of air traffic control surveillance technology and the high-precision detection of air traffic control surveillance equipment urgently need a method that can simulate aircraft trajectory flexibly and accurately. [0003] At present, the domestic trajectory simulation methods mainly include: recording the real aircraft trajectory in the air and calculating the trajectory based on the conditions of the earth spheroid model. The first method is highly accurate but very inflexible...
