Facing the increasingly complex space environment, it is particularly important to approach and capture non cooperative space targets such as uncontrolled spacecraft. In order to solve the rendezvous guidance problem of continuous small-thrust non-cooperative space targets in near-circular orbits, a zero effort convex optimization guidance strategy was proposed by using the rolling convex optimization method and the rolling zero effort miss target distance estimation. It is suitable for both fixed time rendezvous tasks and adaptive time rendezvous tasks. The simulation results show that the fixed-time rendezvous task has a better rendezvous effect than the traditional differential countermeasure method, and the adaptive time rendezvous can complete the rendezvous task in a shorter time, and the method has stable performance and engineering application potential.
