A satellite attitude control method using target track approximation is provided to adjust the attitude of a satellite by making a task plan quickly if the attitude of the satellite needs to be regulated at a track, due to plural photographing regions. A satellite attitude control method using target track approximation includes the steps for inputting coordinate information of at least one target point(401); generating a target track passing all input target points by selectively utilizing an approximation method using a polynomial expression on the basis of coordinate information of the input target points, an approximation method using a Fourier series, and an approximation method using neural network(402,403); and checking the position of a satellite at the present track, calculating an attitude track for the target track by using the present position of the satellite and coordinate information of the target point, and then applying the calculated attitude track to a satellite attitude control operation(404,405).
