Abstract

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
