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.
-
Input message
-
Projection and calibration files (DC file extension)
-
User-defined subgridded geoid
Current application file
The current application file (Current.cfg) reflects the current receiver configuration. When you change the receiver’s configuration, either in real time or by applying an application file, the current file changes to match the new configuration.
You cannot delete the current file or change it directly, but every change to the receiver’s current configuration is applied to the current file as well.
When you switch off the receiver and then turn it on again, all the settings from the current application file are applied, so you do not lose any changes that you have made. The only exceptions are the following logging parameters:
-
Logging rate
-
Position rate
-
Elevation mask
These parameters are always reset to the factory default values when the receiver is switched off.
Power Up application file
The power up application file (Power_up.cfg) is used to set the receiver to a specific configuration any time the unit is powered up.
In this file, you can specify that the receiver is reset to defaults before the power up settings are applied. This ensures that restarting the receiver always resets it to factory defaults before applying the power up application file.
Alternatively, you can specify that the power up settings are applied immediately after the current application file’s settings have been applied. Restarting the receiver results in a configuration that uses your default settings for the options you define in the power up file, but the current settings for all other options.
By default, there is no power_up application file on the receiver. To use a power up application file, you must create and save a power_up application file in the GPS Configurator software. If you save this file to disk, the file is called power_up.cfg. The extension .cfg is used, by convention, to identify application files on the office computer. When you transfer this file to the receiver, the file is saved on the receiver as power_up, and becomes the new power up file.
Applying application files
An application file’s settings do not affect the receiver’s configuration until you apply the application file. You can do this at the same time that you save the file. Alternatively, you can save the file on the computer or on the receiver, then open it later and apply its settings.
Naming application files
The application filename in the office computer and in the receiver are always the same. This makes it easier to recognize and keep track of your application files.
When you change the name of the application file in the receiver, this changes the application filename on your computer. When you transfer an application file from the receiver and save it to the computer, the system renames the file to match the internal receiver file. However, if you use Windows Explorer, for example, to change the .cfg filename on the computer, this does not change the internal receiver filename. This means that the GNSS receiver will not recognize the change to the filename on the computer.
