This invention provides a method for creating a point-beam data transmission mission for a shipborne mobile receiving station to remote sensing satellites. The method includes: using the acquired approximate position and orbital element information of the shipborne receiving station, calculating a set of all approximate visible time windows for the entire day; then using this set to determine the approximate time window for the target data transmission mission; based on the approximate time window, sequentially calculating the ship's geocentric latitude, ship's travel distance, and spherical arc length; determining, based on the spherical arc length, whether the ship's course change exceeds a preset threshold; if so, performing segmented ship position prediction; otherwise, performing direct ship position prediction to obtain a precise predicted ship position; expanding the approximate time window based on the precise predicted ship position to obtain a precise time window; and then using the precise time window and the precise predicted ship position to construct the point-beam data transmission mission. This invention achieves precise planning of the satellite data transmission mission and ensures that the shipborne station antenna points towards the satellite to form a two-way closed link.
