摘要
利用计算机、仿真模拟等技术，虚拟船舶航行环境，仿真模拟GPS导航仪，以解决实装GPS导航仪在教学训练中存在的一些弊端。由于GPS导航仪版本升级换代快，采用软模拟技术代替硬模拟，以使仿真导航仪具有良好的移植性；采用图形显示技术，以逼真仿真导航仪外形；采用图形显示模拟技术和操作功能逻辑模拟技术，并结合实时计算模型，模拟导航仪显示和操作功能；通过建立船舶运动模型，人工输入船舶航向、航速等参数，虚拟船舶海上航行环境，最终实现GPS导航仪的面板仿真、功能模拟与环境虚拟。仿真导航仪不仅具有实装导航仪相同的外型与功能，而且在虚拟航行环境下实现导航仪的综合操作，从而有效提高导航仪教学训练效果。
The use of computer and simulation technologies, virtual navigation environment, simulated GPS navigation device, designed to address the real-installed GPS navigation instrument in teaching and training, where there is still some of the disadvantages. As the upgrade version of GPS navigator fast simulation techniques instead of soft-hard simulation, in order to simulate navigation instrument, it has good portability. The use of graphics technology to realistic simulation Navigator contour; using graphics simulation techniques and operational functions logic simulation technology, combined with real-time computational model, it simulate navigation instrumentto have display and operation functions; Through the establishment of ship motion model, manual entry of the ship heading, speed and other parameters, the virtual ship maritime navigation environment, GPS navigation realizes instrument panel emulation, functional simulation and the Environment Virtual. Simulation Navigator has not only the real equipment and functions of the same appearance, but in a virtual navigation environment to achieve the integrated operation of navigation systems in order to effectively improve the effect of teaching and training navigators.
