However, don’t let yourself become overly confident: Always be cautious! The captain is responsible for cross-checking the system against other sources of navigation data. As your vessel moves from one area to another, the 961/962 Moving between automatically changes from one chart to another, taking your charts chart scale and current zoom level into account.

Your vessel remains centered on the chart, while the chart moves underneath your vessel. When the vessel moves near the edge of a chart, the 961/962 automatically switches to another available chart.

SOG and COG readings result from ongoing measurements derived from the satellite signals; GPS speed is updated every second. You can set the 961/962 to display its SOG and COG readings more smoothly by setting the GPS speed averaging value up to 10 seconds. Increasing this averaging time, however, may reduce overall reaction time.

These signals provide a basis for a navigational system that’s totally independent of the GPS system. The 961/962 automatically converts GPS coordinates to loran TDs, which can be viewed on the CHART screen at any time (as well as other screens). This conversion is known as Northstar’s Phantom loran feature.
