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 immersetube installa tion, a precise positioning system, which includes totalstation and GPS, is designed and used for measurementtower posi tioning in immersetube 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.
