The invention provides an attitude trajectory planning method for satellite non-trace curve imaging, and relates to the technical field of satellite attitudes. The attitude trajectory planning method for satellite non-trace curve imaging comprises the following steps: S1, according to the position of a ground imaging point curve A and the orbit of satellite operation, respectively determining the imaging moment T of a satellite to a ground imaging point, and recording a sub-satellite point position K of the satellite at the imaging moment. According to the attitude trajectory planning method for satellite non-trace curve imaging, by determining the imaging moment T of the satellite to the ground imaging point according to the position of the ground imaging point curve and the orbit of the satellite operation, the ground imaging point can be conveniently selected, and the coverage area and the tracking quality of the curve trajectory are improved. According to the attitude trajectory planning method for satellite non-along-track curve imaging, the high-precision attitude angle and the angular velocity of the attitude angle can be effectively obtained by constraining the curve attitude orientation of the imaging point, so that the effect of improving the attitude trajectory precision of non-trace curve imaging is achieved.
