摘要
为了利用虚拟试验仿真技术研究各种捷联导航算法,提出了舰载捷联导航系统虚拟实验平台的总体方案。根据总体方案设计了平台的总体框架,建立基于MFC和Vega开发试验平台。试验平台主要由三部分核心模块组成:虚拟试验建模,惯性导航仿真和坐标转换,坐标转换是虚拟环境与惯性仿真的桥梁。该平台通过采用面向对象的设计方法,遵循软件的开发规范,验证了平台的可行性和有效性,克服了传统平台编程复杂,扩展性差的缺点,使惯性系统的仿真数据通过虚拟环境的临场感很直观地表现出来。
To evaluate different SINS algorithms using virtual experiment simulation technology, a general scheme for the virtual experiment platform of INS was presented. Based on the scheme, the platform＇s overall framework was designed, and the system simulation of shipboard navigation based on MFC and Vega was implemented. The platform consisted of three core models： virtual experiment modeling, simulating strapdown inertial navigation, and coordinate transition, which is the bridge of the virtual experiment modeling and the simulation strapdown inertial navigation. The platform follows the soRware engineering spec and uses object-oriented programming technique. The experiment shows that the system can easily evaluate the algorithm of navigation system and overcome the disadvantages of traditional platform, such as, complicated programming and bad extension property. In addition, the simulation data of inertial system can be directly indicated by virtual environment.
