5700 Operation
By default, there is no Power Up application file on the receiver. If
you want to use a Power Up application file, you need to create an
application file in Configuration Toolbox and make sure that the As
auto power up file option is selected in the File page. When you
transfer this file to the receiver, it is transferred with the name
Power_up.cfg, and becomes the new Power Up file.
The Power Up file is the only special application file that you can
overwrite or delete from the receiver.
4.4.2 Timed Application Files
A timed application file contains a Timed Activation record which
specifies when this file is to be applied. The main use of a timed
application file is to automatically start or stop logging at a predefined
time.
The Timed Activation record specifies:
• the UTC date and time when the application file is to be applied
for the first time
• the interval at which the file is to be reapplied
If you do not specify a repeat interval, the settings are applied only
once, at the specified time. If the file specifies a repeat interval, the
file’s settings are reapplied at the specified interval until the file is
deactivated.
Defining timed application files
To send timed application files to a 5700 receiver, set up scheduled
survey sessions in GPS Configurator. You can define multiple
sessions, each specifying:
• basic logging parameters (data logging rate, position logging
rate, and elevation mask)
• a starting time
• a duration
