Configuring the receiver to log data for postprocessing
The 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, and that can be used with GPS
postprocessing software such as the Trimble Geomatics Office
™
for the computation
of control networks and baselines.
Note – The SCS900 system does not support postprocessed applications. Trimble
recommends that you use the front panel keypad and display, or the Web User Interface
(SPSx50 and SPSx51 only) , or the GPS Configurator software (SPSx80 and SPSx81 only) to
configure the receiver for postprocessed measurement sessions.
Configuring the receiver in real time
The SPSx80 and SPSx81 Smart GPS antennas can be configured in real time by the GPS
Configurator software.
When you configure the receiver in real time, you use the software to specify which
settings you want to change. When you apply the changes, the receiver settings change
immediately.
Any changes that you apply to the receiver are reflected in the current application file,
which is always present in the receiver. The current application file always records the
most recent configuration, so if you apply further changes (either in real time or using
an application file) the current file is updated and there is no record of the changes that
you applied originally.
Configuring the receiver using application files
An application file contains information for configuring a receiver. To configure a
receiver using an application file, you need to create the application file, transfer it to
the receiver and then apply the file’s settings. The GPS Configurator software does this
automatically when you work with configuration files.
Overview
An application file is organized into records. Each record stores configuration
information for a particular area of receiver operation. Application files can include the
following records:
• File Storage
• General Controls
• Serial Port Baud Rate/Format
• Reference Position
