[. . . ] There are four levels of positioning precision available: · SPS461 DGPS and OmniSTAR VBS (Standard) · SPS461 Location RTK and OmniSTAR HP/XP (Upgrade) · SPS461 Location RTK with precise vertical measurement (Upgrade) · SPS461 Precision RTK (Upgrade) When you purchase the receiver upgrade, your Trimble dealer will provide you with a set of codes to change the receiver configuration. 24 SPSx61 Modular GPS Heading Receiver Getting Started Guide Managing Application Files You can use the front panel to manage application files in the receiver. You can see which application file the receiver is currently using and then choose to make changes to it and save it, load a different application file, or delete an application file. To manage the application files, use the System Setup menu (see the figure below). You can only manage application files when the AutoBase feature is turned off. To save an application file, configure all the settings you need through the front panel and then save the file. When you save the file, the receiver provides a default filename, which you can change, based on the currently set mode. For example: If the receiver is set to the following mode: Base Heading Moving Base Rover The suggested application filename is: BASE01 HDG01 MB01 ROV01 Note ­ If you start an application file that is saved with AutoBase turned on in the file, then it turns on AutoBase in the receiver, even if it was off before the file was loaded. Application file handling through the front panel of the receiver SPSx61 Modular GPS Heading Receiver Getting Started Guide 25 Default Settings All settings are stored in application files. The default application file, Default. cfg, is stored permanently in the receiver, and contains the factory default settings. Whenever the receiver is reset to its factory defaults, the current settings (stored in the current application file, Current. cfg) are reset to the values in the default application file. However, you can create a power-up application file so that the settings in this file can be applied immediately after the default application file, overriding the factory defaults. For more information, see Configuring the receiver using application files. These settings are defined in the default application file.

This means 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 powerup files. When starting any of the SPS receivers as a base station or rover receiver using the Trimble SCS900 site controller software or the HYDROpro software, the settings 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. Logging data 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. Data logging using receivers requires access to suitable GPS postprocessing software such as the Trimble Business Center software. Postprocessed GPS data is typically used for control network measurement applications and precise monitoring. GPS measurement data is collected over a period of time at a static point or points and then postprocessed to accurately compute baseline information. For information on how to enable the Data Logging option, and the required postprocessing software options, contact your Trimble dealer. Logging data after a power loss If power is unexpectedly lost while the receiver is logging data, the receiver tries to return to the state it was in immediately before the power loss. [. . . ] A real-time differential GPS method that uses carrier phase measurements for greater accuracy. SBAS is based on differential GPS, but applies to wide area (WAAS/EGNOS/MSAS) networks of reference stations. Corrections and additional information are broadcast using geostationary satellites. The signal strength of a satellite is a measure of the information content of the signal, relative to the signal's noise. [. . . ]
