GNSS Receiver Properties - Station Information

When you add the GNSS Receiver module, the GNSS Receiver Properties dialog appears with this tab.

If you select the module in the Tree view after you have added the module, the categories and settings of this tab appear in the Properties view.

Use the Station Information tab to view and select the station the module connects to, as well as receiver information and the settings the system needs to use the matching decoder type for the receiver.

Station Information category

The Selected station specifies the station, which provides input of real-time GNSS observations. Per default, the value is empty, when you add a new module configuration. To select a station, set the focus onto the Selected station setting and click the browse button. This opens the Select a Station dialog, where you can select a reference station from the list. Using that dialog, you can also add, copy, and remove stations, or view and edit the settings of existing stations, including station ID and name, position, antenna and receiver information as well as information on the site operator.

If the receiver serial number and firmware version are fed into the system (for example, from active connections or from imported station files), they are also stored internally.

After you have selected the station, the additional Receiver Information and Decoder categories appear.

Receiver Information category

The settings of this category are only available for viewing, after a station has been selected, and for editing, after the module has been added to the system. The values of the Manufacturer, Name, and Firmware settings are automatically filled with the information stored for the selected station in the global station list. However, you can edit these values here; the settings in the global station list will then be updated with the new information. Receivers with active connections send their firmware information which automatically overwrites existing entries.

After you have selected a receiver manufacturer and receiver type, additional settings pages, categories and properties may become available, referring to this receiver type. Among these features are the following:

If a receiver type supports GLONASS or L5 processing, additional settings are available at the Receiver Data tab > Receiver Control category.
Some Trimble receivers can store observation data files to their internal memory. With such a receiver type selected, additional settings for external configuration of the data logging are available at the Data Logging tab > Data Logging category.
Other Trimble receivers can request data from external sensors and pass them through the system. The External Sensor properties become available.
If receivers require authentication, the Decoder group displays the additional Receiver requires login setting.

Decoder category

A decoder is a Dynamic Link Library (DLL) module, which is designed for communicating with one specific type of receiver.

Decoder group: Specifies the type of decoder. The following selections are available:

BINEX:	Only available for Trimble and Topcon receivers capable of sending BINEX data. Decodes incoming BINEX data. Passive connection to the receiver.
CMRx:	Only available for Trimble receivers. Decodes incoming CMRx data. Passive connection to the receiver.
Real-time:	Decodes the receiver proprietary messages.
Remote download:	Only available for Trimble receivers. Decodes post-processing data which have been internally stored at the receiver. If selected, additional settings are available at the Remote Download tab > Remote Download category.
RTCM3:	Uses RTCM v.3 messages (including RTCM Multi Signal Messages 4...7) fed in by the receiver.

Note - The data streams contain information on the receiver type sending them. If the GNSS Receiver module does not support the receiver type or if the receiver is not contained in the current software license, the module will be set to the Invalid receiver type (infected) status.

Communication mode: Only available for Trimble receivers in Real-time decoder mode. Specifies how Trimble 4D Control Server controls the connected receiver. The following selections are available:

Passive:	Unidirectional. The settings for the GNSS Receiver module are not transferred to the connected receiver. Some receiver data properties are not available.
Active - "fire and forget":	An active, unidirectional connection. The GNSS Receiver module sends any change of its settings over the "incoming" port to the connected receiver, but it does not expect any response. The module will not know, whether or not the setting changes are respected by the connected receiver.
Active - waiting for response:	An active, bi-directional connection. Allows the GNSS Receiver module to apply changes to its settings also to the connected receiver. If the receiver responds with having denied the setting change(s), a warning message will be issued and appear in the Status Messages view. If the receiver does not respond, the Communication mode setting will automatically change to Active - "fire and forget". Additionally, a warning message will be issued and appear in the Status Messages view.

Receiver requires login: This setting is only available for receiver types, which may or may not restrict the communication to known users. If set to Yes, the additional Login name and Password settings let you edit the login credentials.
