Speed reference system is built, using information of heading, position and timeof Trimble S860 DGPS attitudedetermination system. Exper imental results verify the method s validity. ore accurate measurement, convenience detection and automatic operation are achieved compared to the old ways. ey words: Log; GPS; attitudedetermination; mid- latitude sailing method 0 ; , , DGPS , , DGPS , [ 1] , , , , , GPS , , , GPS , , , , , GPS , , , , :2004- 01- 10;:2004- 01- 24 1 MS860 DGPS : ( 1972- ) , , , , INS/ GPS , GPS GPS (1942- ) ,, , ,
