Abstract This study investigates the scheduling problem of multiple agile optical satellites with large-scale tasks. This problem
is difficult to solve owing to the time-dependent characteristic of agile optical satellites, complex constraints, and
considerable solution space. To solve the problem, we propose a scheduling method based on an improved sine
and cosine algorithm and a task merging approach. We first establish a scheduling model with task merging
constraints and observation action constraints to describe the problem. Then, an improved sine and cosine
algorithm is proposed to search for the optimal solution with the maximum profit ratio. An adaptive cosine factor
