Carrier Phase mode
For applications in which accurate data is required, you can configure
the Asset Surveyor software to record GPS carrier phase data,
provided your GPS receiver is capable of computing such data. You
can subsequently process this data with the GPS Pathfinder Office
software to yield accuracy of a few decimeters.
Note – For more information on how to collect carrier phase features
see Chapter 7, Carrier Phase Data Collection.
Pausing and resuming
If you need to move away from a point feature (for example, to see the
top of a power pole more clearly) or need to avoid an obstacle when
recording a line or area feature, presspto avoid recording
inappropriate GPS positions. Logging of GPS positions for the feature
halts, and thepsoftkey changes toL. Return to the position
you want to record pressL and to continue logging GPS positions.
Normally, the Asset Surveyor software logs GPS positions while you
enter attributes, but you can separate these two activities and perform
them in either order usingpandL.
– Each time you resume logging while collecting a line or area feature,
the Asset Surveyor software logs a GPS position immediately
(irrespective of the logging interval for line/area features). You can use
this feature to force the Asset Surveyor software to log a GPS position
when you come to a corner or a point of interest. Presspand then
Lto cause the current GPS position to be logged. AfterLis
pressed, the Asset Surveyor software continues logging GPS positions at
the configured line/area logging interval.
