The GPS100 computes Course Over Ground (COG) by observing prior fixes or positions and extrapolating the direction of travel from those fixes. If the vessel is not moving, then the GPS100 can not extrapolate the direction of travel and the readings... Read More

You display the GPS100 Course Over Ground (COG) information on a DSM150, DSM200, or DSM250 in the following way: Enter menu mode, scroll to "Favorite Screen Setup..." and press Scroll to the favorite screen where you would like to view the COG and... Read More

In order to display true wind referenced to ground speed you will need a WSO100, a GPS200, a SSC200, and a display capable of computing true wind referenced to ground speed. The WSO100 measures the apparent wind while the GPS200 provides Speed Over... Read More

The GPS100 is a 12 channel global positioning system antenna and receiver with Satellite Based Augmentation System (SBAS) capabilities. This includes SBAS for North America (WAAS), Europe (EGNOS), and Asia (MSAS). The GPS100 provides time and date,... Read More

The SSC200 receives the following NMEA0183 sentences or messages: RMC - Recommended Minimum Specific GNSS Data VTG - Course Over Ground and Ground Speed PMAREXE - Maretron Proprietary Execute Sentence PMARSETPX - Maretron Proprietary Set Period... Read More

The WSO100 is generally placed at the highest point on the vessel so that it is not obstructed from the wind. Unfortunately, the highest point on a vessel is often the worst possible placement for a GPS or compass. Take for example a GPS mounted at... Read More

A standard Maretron NMEA2000 navigation sensor network consists of the following components: Compass: SSC200 GPS: GPS200 Depth Speed Water: DST110 Weather: WSO100 Display: DSM150 System Capabilities: Wind Apparent Speed over ground Course... Read More

The GPS100 transmits the following messages (or PGNs): PGN 126992 - System Time (Fields: 1-SID, 2-Time Source) PGN 128259 - Speed (Fields: 1-SID, 2-Speed Water Referenced, 3- Speed Ground Referenced, 4-Speed Water Referenced Type) PGN 129025 -... Read More

The GPS100 provides the following information: latitude and longitude time and date Course Over Ground (COG) Speed Over Ground (SOG) magnetic variation satellite information Given this information from the GPS100, Maretron display products (DSM150,... Read More

Speed Over the Ground (SOG) is the speed of the vessel relative to the surface of the earth. Speed Through Water (STW) is the speed of the vessel relative to the water. It is possible for the STW to be zero while the SOG is 5 knots, for example if... Read More
