Why Heading Sensors Make Sense
Nobeltec’s April newsletter discusses why it makes sense to use a heading sensor, even if you already have a GPS device connected to your chart or radar instruments.
“Many users attempt to use the Course Over Ground (COG) sentence provided by their GPS unit to either stabilize the chart or radar image. However, COG is only reliable when the vessel velocity is in excess of 10 knots, and there is not a strong current or wind. Using a heading sensor allows the Nobeltec software to properly align the chart or radar overlay images as well as ARPA targets on the chart.”
