LED behavior The three LEDs on the front panel indicate various operating conditions. Generally, a lit or slowly flashing LED indicates normal operation, a LED that is flashing quickly indicates a condition that may require attention, and an unlit LED indicates that no operation is occurring. The following table defines each possible LED state: The term . . . Slow flash Fast flash On Off means that the LED . . . alternates rapidly on/off for 100 milliseconds is lit steady is unlit LED flash patterns The following table details the possible flash patterns to indicate various states of receiver operation.

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. You cannot modify 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. Default receiver settings These settings are defined in the default application file.

SPS882 Smart GNSS Antenna Getting Started Guide 15 For more information on the GPS Configurator and Configuration Toolbox software, see Configuring the Receiver Settings. Default behavior If a power-up application file is present in the receiver, its settings are applied immediately after the default settings. 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 power-up 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. By default, the Data Logging option is turned off. 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. The receiver does not reset itself to default settings. [. . . ] The signal strength of a satellite is a measure of the information content of the signal, relative to the signal's noise. The typical SNR of a satellite at 30° elevation is between 47 and 50 dBHz. The satellite skyplot confirms reception of a differentially corrected GPS signal and displays the number of satellites tracked by the GPS receiver, as well as their relative positions. The NTripCaster maintains a source-table containing information on available NTripSources, networks of NTripSources, and NTripCasters, to be sent to an NTripClient on request. [. . . ]
