high precision positioning system meaning in Chinese

高精准定位系统

For the two parts mentioned above , this paper introduces a high precision positioning system for underwater application , which is made up of dgps and acoustical ultra short baseline . in this positioning system , the emphasis has been put on the mathematical model for positioning computation , and based on the model the author has given computer simulation results for positioning computation
在本论文中，介绍了一套由dgps和水声超短基线构成的水下精确定位系统，重点建立了用于此系统定位解算的数学模型，进而以该模型为基础进行了定位解算的计算机模拟仿真，仿真结果进一步验证了数学模型的正确性和系统的可行性。
