The DVL can accept inputs of its current latitude and longitude in several formats. If you are typing by hand, the SET-POSITION should be used (vs. trying to type in a $GPRMC message by hand). The DVL recognizes Decimal Degree (DD) format, Degree Decimal Minute (DDM) format, and Degree Minute Second (DMS) format. DD is used when you have lat/long in positive and negative degrees, such as what Google Maps shows. DDM format is used by many marine GPS systems.


DD format: SET-POSITION 44.968876,-93.517246

DDM format: SET-POSITION 44 58.13256 N, 93 31.03476 W

DMS format: SET-POSITION 44 58 20N, 93 31 03W
