The invention provides a planning control method and device for a space target pointing attitude by a remote sensing satellite, and the method comprises the steps: obtaining an attitude quaternion from a satellite body system of the remote sensing satellite to a load coordinate system, acquiring a satellite orbit state and a space target orbit state at the current moment; determining the intersection moment of the remote sensing satellite and the space target through an orbit pre-pushing model; and determining the shooting time of a linear array camera based on the intersection time of the remote sensing satellite and the space target, and obtaining the space unit vector of three axes of a satellite load coordinate system corresponding to the expected attitude of the remote sensing satellite at the shooting time. According to the invention, the imaging of the line-scan digital camera is more accurate, the control precision of the pointing attitude of the remote sensing satellite is improved, and the problem of poor control effect of the remote sensing satellite in the prior art is solved.
