The invention relates to the technical field of carrier rocket guidance control, in particular to an atmospheric external guidance control method for a solid carrier rocket. The atmospheric external guidance control method for the solid carrier rocket comprises the following steps that a three-stage engine takes a bound last-stage starting point position as a target point and bound last-stage starting time as a constraint, and closed-circuit guidance is carried out after the three-stage engine is ignited; three-stage sliding trajectory planning is carried out on the basis of a last-stage iterative guidance algorithm, and last-stage starting time is calculated; and after the last stage is started, iterative guidance is carried out to calculate a flight program angle until the last stage is shut down. According to the atmospheric external guidance control method for the solid carrier rocket provided by the invention, through closed-circuit guidance of a three-stage active section and trajectory planning of a th
