The Velocity value is used in positional filtering. The lower the value entered, the
more smoothing that is applied.
Remote Unit ID:
The Remote Station ID parameter is set to zero (0) unless the GPS device is
interfaced to WinFrog via a telemetry device.
Multiple Position Source Options:
This group box allows you to enable automatic switching of a secondary to primary
should the data from all POSITION and PSEUDORANGE data items set to primary
timeout. The Age entered is the length of time that the secondary will wait in the
absence of data from all primaries, before taking over as primary. This age is only
entered for the secondary.
For example, if the POSITION or PSEUDORANGE data items associated with two
GPS receivers were set to primary and the POSITION or PSEUDORANGE data
item of a third GPS receiver was set to secondary, both primary GPS receivers must
time out before the secondary will become the primary. Upon the recovery of either
of the original primary data items, the original primary will be reset to primary and the
original secondary will be reset to secondary.
Note for the auto switching feature to work, there must be at least one primary and
one secondary enabled. For example, given two data items, one set to primary with
the auto switching disabled and the other set to secondary with the auto switching
enabled, if the primary fails the secondary is not set to primary and the vehicle
positioning stops until the primary data item recovers.
Disable Auto Switching of Primary:
If this data item is not to be involved in the auto switching process, check this
box. As stated above, this data item is then not involved in the auto switching
process in any way.
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
