The following items are available for configuration:
Calculation:
Set the Calculation selection to Primary or Secondary. Devices set to Primary
calculation are used to provide a vessel position. Note that more than one Primary
positioning device can be added to a vehicle's device list; data from these devices
will be combined in a weighted mean solution. (See the paragraph on Accuracy
below for more on the weighting of Primary calculation device data).
If the Calculation type is set to Secondary, WinFrog will simply monitor the device's
data. WinFrog will not use the data from a secondary device in the final solution of
the vehicle's position.
If auto switching is enabled (see below) a secondary may automatically become a
primary should all the primaries fail.
Use For Heading Calculations:
Select this checkbox if this GPS position is to be used in conjunction with another
GPS device for determination of the heading of the vessel. The vessel's heading will
be derived by the inverse of the GPS antenna coordinates.
Graphics:
If On is selected, a labeled square will be made visible in the Graphics and Bird's
Eye displays, depicting the raw (unfiltered) location of the GPS antenna. This
provides a means of comparing raw and filtered positions between different sources.
