AbstractShipboard optical measurement equipment is affected by ship swaying, and a fixed order, such as “yaw, pitch and roll”, is always adopted to realize the mutual conversion between the earth reference frame and the deck reference frame. This paper simulates the solving model on six different coordinate transformation orders, finds that its error is great and it will affect the shipboard optical measurement equipment’s pointing precision of LOS (line of sight), so we put forward a LOS stabilization model based on subdivision iterative algorithm. Through the simulation and analysis, the new model can let all coordinate calculation value of different switching sequence converge to the true value, and it will improve the accuracy of existing solution model. The method is significant to improve the tracking control accuracy and data processing precision of angular measurement.
