The C-SCAN 2010 System has a fully integrated built-in global
positioning capability. The accurate longitude and latitude
of every survey location can be recorded and displayed and
will appear in the survey report. The ‘straight line’ distance
from any previously stored survey location will be automatically
calculated and displayed and if required, can be entered
into the calculation of ‘signal attenuation’ over each section
of line. This can be over-ridden by the operator who can
enter another value for ‘distance’ if required (surveying
round corners, bends, etc).
The GPS data (longitude and latitude)
can also be recorded for individual faults located during
a survey. This will assist subsequent monitoring or rapid
excavation and repair if required.
The GPS information is downloaded
from the worldwide GPS satellite network using the C-SCAN
2010’s built-in GPS antenna and processed using Dynalog’s
proprietary software.
Positional accuracy will usually
be better than +/-5 metres. This information can be acquired
rapidly and is generally sufficient for most purposes.
A standard hand-held GPS system
can be connected to the C-SCAN 2000 unit provided a suitable
interface is available. Depending on the characteristics
of the GPS unit being used, positional data can then be
downloaded to the detector and incorporated into the data
record.
