Trimble R7 GPS Receiver Operation
The power up file is the only special application file that you can
overwrite or delete from the receiver.
53.2 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.
Note – If the receiver is logging continuously, the current logging takes
precedence over any timed application file stored in the receiver.
Defining timed application files
To send timed application files to a Trimble R7 receiver, set up
scheduled survey sessions in the GPS Configurator software. You can
define multiple sessions, each specifying:
• basic logging parameters (data logging rate, position logging
rate, and elevation mask)
• a starting time
• a duration
