The Design of Measurement Error Correction System for Ship Optical Theodolite

摘要

The ship measurement device to perform the measurement task, influence by wind, tide and experience of ship hull navigation, drift motion, swing movement: the tracking measuring element will be the superposition of these rolling motion affect measurement accuracy. To eliminate the influence of the ship shaking data when carrying on the follow-up processing. In order to meet the needs of the flight test and control of the sea, it is necessary to make up for the limitation of the use of the fixed station and the mobile station of the vehicle by means of optical theodolite equipment loaded on the ship. In this paper, based on the practical engineering requirement, the measuring system composed of small ships in ship loading optical theodolite, the measurement data are developed ship swaying error model obtained can effectively eliminate the effects of processed ship data and ground-based optical theodolite data processing method, and designs a reasonable ship optical theodolite data process. The data processing of error correction, system error correction and target track calculation of optical measurement data are realized.
