Using the SCS900 Site Controller software to configure the
base station, rover, and the radios
As a total system solution for construction applications, the SPS GPS receivers are
operated by a TSCe
™
, ACU, TCU, or TSC2 controller running the SCS900 Site
Controller software. The SCS900 system provides the tools to configure and start the
GPS receiver in the modes used by the SCS900 system: Base Station, RTK Rover,
Location RTK Rover, OmniSTAR Rover, and DGPS Rover using SBAS (WAAS/EGNOS
and MSAS). The SCS900 software provide wizards to help you through the process and,
where possible, assigns suitable default operational parameters to the system. This
eliminates the need for an operator to know how to configure the receiver with the
right settings.
The SCS900 system takes care of operating the receiver with both internal and external
radios, cellular communications components (modems and cellphones), and use of the
Bluetooth wireless technology. The software also takes care of scanning
communication ports to identify connected devices, and offers selection options
wherever necessary often with pictures to facilitate the correct component selection at
times when it cannot automatically identify the connected component, for example,
GPS antennas.
The SCS900 system allows you to specify operational tolerances, which have to be
achieved for measurements to be accepted. When outside of these tolerances, the
SCS900 system warns you through on-screen messages or indications, and the non
automatic acceptance of recorded positions. To set operational tolerances, go to the
the Settings menu in the SCS900 software.
Configuring the receiver to log data for postprocessing
The SPS GPS receivers do not come equipped with the Data Logging option. The
receivers can have this added either at the time of purchase, or at a later date as an
option. With the Data Logging option enabled, the receiver has available memory, that
facilitates the collection of GPS observations over a period of time, which can be used
with GPS postprocessing software such as Trimble Geomatics Office or Trimble Total
Control, for the computation of control networks and baselines.
