3.6 Chart: Position data sources
The GB40 can receive Lat/Long coordinates from several sources,
depending on the type of receivers that are connected. These
include:
• GPS
• GPS enhanced by WAAS
• GPS enhanced by DGPS
• Loran or Phantom Loran
GPS satellites are the primary source of position data but,
depending on the type of receivers that are connected to your
GB40 and your personal preferences, you can choose to display
your vessel's position as Lat/Long coordinates OR as Loran Time
Differences (TDs) coordinates.
Loran coordinates can be calculated from the GPS coordinates (this
is known as Phantom Loran).
