航行训练模拟器陆标定位功能的模拟与实现

Design and Realization of Terrestrial Fixing Function Simulation in Navigation Training Simulator

结合船舶航行操作训练实际,在视景仿真系统中开发陆标定位功能,介绍潜艇航行训练系统的组成及功能。针对某型船舶所用方位仪对陆标定位功能进行模拟罗经功能设计,基于GDI+的方式实现罗经的模拟开发。基于实际地形高程数据对地形场景进行建模,并依据电子海图等相关数据对助航标志和地貌特征等进行定位。通过实验比较分析,船舶训练模拟器中的方位定位结果符合真实地形数据,可以满足船员方位定位训练的需求。

To meet the requirements of terrestrial fixing function simulation in navigation training simulator, a method based on scene simulation is proposed in this paper. At first, the constitution and functions of submarine navigation training system is presented. And then, a GDI ＋ based method is used to simulate the compass used for cross bearing fixing. And to ensure the veracity of terrestrial fixing function in scene simulation ＂system, the terrain is modeled based on true DEM, the beacons and physiognomy trait are located according to the digital chart. The results show that, the fixing by cross bearing results in simulation system is tally with the real terrain data and the simulated terrestrial fixing function can meet the requirements of training.
