Abstract Roll–pitch seeker is currently applied in particular missiles. There is a stubborn problem called zenith pass problem while roll–pitch seeker is used. Analysis of the zenith pass problem which always results in loss of target is presented in this paper. Based on the analysis result, tracking strategy is carried out to deal with zenith pass problem. To prove the validity of tracking strategy, a practical roll–pitch seeker was accomplished. Model identification and common PID controllers for the physical roll–pitch seeker are taken on, after that, both disadvantages derived from zenith pass problem in tracking process and meliorated phenomenons by the tracking strategy are shown. It is concluded that the tracking strategy designed for solving the zenith pass problem is efficient.
