Abstract: Due to the shortcoming of electronic chart displaying and information system in navigation practice,a kind of electrical chart work is put forward in this article.The method of weighted least square estimates (WLSE) is modeled and demonstrated to be used in fixing by cross bearings.Matlab simulation calculation shows that some weakness should be noticed to benefit the hope that navigation chart work can be done on electronic chart displaying and information system.

Key words: chart work;electrical chart work, weighted least square estimates
