摘要/Abstract

摘要： 在建立海洋大地测量控制网的过程中，通常采用GNSS/声学结合定位的方式确定海底控制点位置。本文从船载动态定位、测船航迹及航迹点个数、水下声学定位、应答器阵列性能等方面对影响GNSS/声学系统定位精度的因素进行了详细讨论，并通过设计仿真试验进行了定量验证。试验模拟了圆阵列形式布设的控制点，采用海上GNSS实测数据和模拟水下测距数据，分别分析了系统在3类主要因素影响下的定位效果。结果表明，提高船载GNSS动态定位精度、适当增加航迹点和数据观测量、设计合理的应答器阵列构型可以削弱误差影响，得到更准确的定位结果。

Abstract: In the process of establishing the ocean geodesic control network, the positioning of the seafloor control point is usually determined by using the combined way of GNSS/acoustic. In this paper, the influence factors of GNSS/acoustic system positioning accuracy are discussed in detail, such as dynamic positioning of ship borne GNSS, surveying ship track and the numbers of measurement points, underwater acoustic positioning and the performance transponder arrays. Then the simulation experiments are designed for quantitative validation. The experiment simulates the control points in the form of a circular array. The GNSS measured data on the sea and the simulated underwater range data are used to analyze the positioning performance of the system under the impact of three main factors. Results show, the error influences can be weakened and more accurate positioning results can be obtained through the following ways:the improve of dynamic positioning accuracy of ship borne GNSS, the appropriate increase of measurement points numbers or observation amounts and the reasonable design of transponder array configurations.

Key words: GNSS/acoustic system, dynamic precise point positioning, surveying ship track, acoustic positioning, transponder arrays
