Abstract:

To solve the problem of information fusion of integrated navigation system, a new simulation platform is designed to study information fusion of integrated navigation system. The platform includes six modules: integrated navigation information fusion simulation and evaluation console, inertial equipment simulator, non-inertial equipment simulator, integrated navigation system simulator, electronic chart system, and data analysis server. The console adopts a new ship motion parameter generator to simulate and generate ship motion parameters under various sea conditions; the integrated navigation simulator adopts a parallel operation mode of various fusion algorithms to facilitate the comparison of the performance of different algorithms; the data analysis server adopts high-performance computer to simulate the public computing environment, and can study the information fusion method that the future ship hardware and software computing resources are considered. The system testing shows that navigation information fusion process and effect meet the requirements, and the designed platform system works well. The platform can be directly used for engineering research and development such as the design, analysis, test and evaluation of the ship information fusion algorithm.
