Three-dimensional flight profile coordinate calculation method

The invention discloses a three-dimensional flight profile coordinate calculation method. The method is characterized by comprising the following steps of: calculating time granularity p according togiven time granularity; a track band width initial value bs; a track band width end value be; total voyage L, track band thickness h, the initial value [mu] s of the track roll angle; calculating sideline three-dimensional coordinates (Xi, Xi) of a flight path zone under the ground coordinate system according to the flight path roll angle end value mu e, the flight path inclination angle initialvalue gamma s, the flight path inclination angle initial end gamma e, the flight path deflection angle initial value Xs, the flight path deflection angle end value Xe, the aircraft vacuum speed initial value Vs and the aircraft vacuum speed end value Ve; wherein the three-dimensional coordinates (Xf, Yf, Zf) of the front face of the track band and the three-dimensional coordinates (Xb, Yb, Zb) ofthe back face of the track b
