Enable Auto Switching of Primary:
If this data item is to be involved in the auto switching process, either as a
primary or a secondary, check this box. If set to secondary, enter the Age of data
the primary data items must reach before this secondary is switched to act as the
primary.
In order for this option to be effective you must have at least one primary and one
secondary. If there are multiple secondary data items that are enabled for switching,
the first one to receive data will become primary.
Note: This option is not enabled unless WinFrog determines that there is more than
one POSITION and/or PSEUDORANGE data item associated with the respective
vehicle. The exception to this is the case of a WinFrog with the Remote module
operating as a Controlled Remote being configured remotely from the Controller. In
this case, the option is always enabled even though it may not be applicable. The
operator must be aware of what is available on the Remote and configure the data
item accordingly.
Note: This option is not available in the WinFrog Remote package.
Note: This option is not available for USBL based POSITION data items.
Offsets:
Offsets are entered to relate the GPS antenna position to the vessel's Common
Reference Point (aka CRP). Offsets are entered as measured from the CRP (of the
vehicle) to the device (antenna) location. Offsets Fore and Starboard are entered as
positive values, Offsets measured Port and Aft are entered as negative values.
Rule of thumb suggests the CRP "Z" reference should be at the water line.
GPS, CONSOLE, PSEUDORANGE
The PSEUDORANGE data item must be edited once it is added to a vehicle's device
list. Highlight the data item in the vehicle's device list and click the Edit button. The
Pseudorange Calculation dialog box appears as seen below.
