[. . . ] This ensures that restarting the receiver always resets it to factory defaults prior to 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. To use a power up application file, you must create and save a power_up application file in the GPS Configurator software. 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. Alternatively, you can save the file on the computer or in the receiver, then open it later and apply its settings. Storing application files You can store application files that you create in the GPS Configurator software on the receiver and on the computer. For example, each file can represent a different user sharing the same receiver, or a particular mode of operation. Saving application files on your computer as well as in your receiver is optional, but it is useful because: · it gives you a permanent copy of the settings you have sent to a receiver, for audit or your own reference. you can use the same file to configure multiple receivers identically. SPS882 Smart GPS Antenna User Guide 49 · 6 Configuring the Receiver Settings · you can use an existing application file as a template to create other application files with similar 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 GPS receiver does not recognize the change to the filename on the computer. Creating and editing the configuration files that control the receiver The Configuration Toolbox software enables you to create and edit GPS receiver configuration files. The settings in these files control the operation of the GPS receiver. The GPS receiver configuration file can then be copied and sent to the receiver. You can also create a file, called an application file or appfile, (*. cfg), which contains all the receiver settings necessary for a particular job or application. Multiple files can be maintained to represent multiple users sharing a device and/or multiple modes of operation. You can also save files to audit the operating settings of a receiver. For applications requiring real-time positions in any coordinate system other than WGS-84, you need the Configuration Toolbox software to define and transfer the necessary coordinate system and transformation parameters. This includes the files default. cfg and current. cfg, which always reside in the receiver. [. . . ] All Trimble GPS receivers use Version 2 protocol for single-frequency DGPS type corrections. Carrier phase corrections are available on Version 2, or on the newer Version 3 RTCM protocol, which is available on certain Trimble dual-frequency receivers. The Version 3 RTCM protocol is more compact but is not as widely supported as Version 2. A real-time differential GPS method that uses carrier phase measurements for greater accuracy. [. . . ]
