基于多系统的浅水区管节沉放对接精密定位方法

摘要

为满足浅水区管节沉放和对接对自动化、高精度和高可靠性定位的需要，设计了基于测量塔全站仪和GPS的精密定位系统，并给出了一套完整的数据处理理论和方法。将该系统应用于管节沉放对接试验中，取得了优于2 cm的定位精度，从而验证了该系统及其数据处理方法的正确性。%In order to meet with the requirement of automation,high accuracy and high reliability in immerse-tube installa-tion,a precise positioning system,which includes total-station and GPS,is designed and used for measurement-tower posi-tioning in immerse-tube installation. Besides, a completed theory and method for the data processing in the system is given out in the paper. Using the synthetic system in an experiment,a positioning accuracy,which is better than 2 cm,was achieved, and thus the valid of the theory,method used in the system as mentioned in this paper was verified.
