摘要:

为评价地图匹配辅助导航参考地图的导航性能,本文定义的统计特征参数新增加了数据采集平台采样周期和测量精度2个参数. 用数值仿真的方法进行了导航精度试验. 其地图匹配算法采用较通用的递归处理匹配算法. 利用实验结果建立了导航性能与新的统计特征参数之间的关系模型.

Abstract:

In order to evaluate the matching ability of the reference map in a map-matching aided navigation system, both of the sampling cycle and measurement precision of the onboard data collection system were introduced in the statistic parameters. Experiments of navigation precision have been done by numerical simulation. A recursive algorithm is adopted as the map-matching algorithm in the simulation. The relationships between the new parameters and map-matching ability were found based on the simulation results.

Key words: data map, aided navigation, characteristic, dynamic
