Default behavior
The factory defaults specified on page 66 are applied whenever you start the receiver. If
a power up application file is present in the receiver, its settings are applied
immediately after the default settings, so you can use a power up file to define your
own set of defaults. The factory defaults are also applied when you perform a full reset
of the receiver because resetting the receiver deletes the power up files.
When starting any of the SPS GPS receivers as a base station or rover receiver using the
Trimble SCS900 site controller software or the HYDROpro
™
software, the settings as
required for those operations are automatically set and configured in that software. To
change the receiver settings for special applications or for use with third-party
software, use the GPS Configurator software or the Configuration Toolbox software.
Power up settings
When you turn off the receiver, any changes that you have made to logging settings are
lost and these settings are returned to the factory defaults. Other settings remain as
defined in the current file. The next time you turn on the receiver, the receiver checks
for a power up file and, if one is present, applies the settings in this file.
Logging data
Logging data with the SPS GPS receivers is available as an option. By default, the data
logging option is turned off. For information on how to enable the data logging option,
and the necessary postprocessing software options, please contact your Trimble
dealer.
Data logging using GPS receivers requires you to have access to suitable GPS
postprocessing software such as Trimble Geomatics Office
™
or
Trimble Total Control
™
. Data logging involves the collection of GPS measurement data
over a period of time at a static point or points, and subsequent postprocessing of the
information to accurately compute baseline information. Postprocessed GPS data is
typically used for control network measurement applications and precise monitoring.
The following information only applies if you have the Data Logging options enabled in
the receiver, and that you intend to carry out GPS postprocessed measurement
operations.
Logging data after a power loss
If the receiver loses power unexpectedly, when power is restored the receiver tries to
return to the state it was in immediately before the power loss. The receiver does not
reset itself to default settings. If the receiver was logging data when power was lost
unexpectedly, it resumes logging data when power is restored.
