When you add the Device Manager module, the Device Manager 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 General Settings tab to view and edit the Device Manager properties for various thresholds and satellite settings.
The settings of this group are used in combination with the Alarm Manager module. They apply, if you have set an alarm for the case that no data are received at multiple stations.
All stations missing: Set this option to Yes for an alarm that notifies you, if data from all stations are missing. Default: No.
Number of missing stations: Only available, if is the All stations missing setting set to No. If as many or more stations do not receive data as defined here, an alarm is triggered. Default: 3 (at least three missing stations).
Note - Depending on the connection type established between Trimble 4D Control Server and the receiver, the settings for the satellites control the receiver (if a bi-directional connection is established) or not (GNSS Receiver module in passive mode).
Track unhealthy satellites: Typically, unhealthy satellites are not tracked or used in the position solution. Some receivers, however, can be set to output the observations of unhealthy satellites. With the Track unhealthy satellites property set to Yes, these observations go into the Trimble 4D Control Server system. They are passed on to Router modules, and they are written into data storage files, such as RINEX files. However, the raw data analysis removes unhealthy satellites from the data; thus, they are not used in the position solution. Default: No.
Disable GPS satellites: Shows the number of GPS satellites, which are currently disabled either for real-time application or also for post-processing. To view or change the GPS satellite selection settings, set the focus onto the Disable GPS satellites value field and click the browse button. This opens the En/Disable Satellites dialog with the current settings for GPS satellites. Per default, no satellite is disabled.
Disable GLONASS satellites: Similar to the Disable GPS satellites setting. Displays and handles the selection of GLONASS satellites. If you click the browse button, the En/Disable Satellites dialog appears displaying the selection of GLONASS satellites.
Disable Galileo satellites: Similar to the Disable GPS satellites setting. Displays and handles the selection of GALILEO satellites. If you click the browse button, the En/Disable Satellites dialog appears displaying the selection of Galileo satellites.
Disable QZSS satellites: Similar to the Disable GPS satellites setting. Displays and handles the selection of QZSS (Quazi Zenith Satellite System) satellites. If you click the browse button, the En/Disable Satellites dialog appears displaying the selection of QZSS satellites.
Disable BeiDou satellites: Similar to the Disable GPS satellites setting. Displays and handles the selection of BeiDou satellites. If you click the browse button, the En/Disable Satellites dialog appears displaying the selection of BeiDou satellites.
Scintillation index filter: The Trimble 4D Control Server raw data analysis functionality calculates for the current ionospheric scintillation index numbers between 0 (no ionospheric scintillation) and 10 (highest value). Use this setting to filter for satellites with an ionospheric scintillation index higher than a threshold. With the default setting Off, the ionospheric scintillation is not respected for disabling satellites. For enabling a filter according to ionospheric scintillation values, select one of the thresholds. There are three thresholds available for selection: With Low (3) selected, the observations of all satellite with a comparatively low scintillation index of 3.0 and higher are excluded from the internal real-time data stream (for example, they are not forwarded to a Synchronizer module and thus excluded from processing). The Medium (5) and High (7) selections are less restrictive, they filter for an index of 5 respectively 7.0 and higher.
The settings of this category of properties apply to the raw data analysis of the real-time data received by all GNSS receivers managed by this Device Manager module.
Note - SNR filtering is not applied to data storage. Data is written to files as it is received.
Enable SNR filtering: For improving the raw data, it can be filtered according to its Signal-to-Noise ratio. By default SNR filtering is not enabled. For enable SNR filtering for one or several frequencies, select Yes. Additional frequency selection options become available.
CA/P1/E1/B1: Only available, if the Enable SNR filtering property is set to Yes. Specifies the threshold of the Signal-to-Noise ratio [in db/Hz] for code on L1 frequencies of the supported satellite systems. Default is 30 db/Hz, data below this threshold will not be used for real-time processing.
L2/L2C/L2CA: Only available, if the Enable SNR filtering property is set to Yes. Specifies the threshold of the Signal-to-Noise ratio [in db/Hz] for code on L2 frequencies of the supported satellite systems. Default is 20 db/Hz, data below this threshold will not be used for real-time processing.
L5/E5/E5A/E5B: Only available, if the Enable SNR filtering property is set to Yes. Specifies the threshold of the Signal-to-Noise ratio [in db/Hz] for code on L5 frequencies of the supported satellite systems. Default is 25 db/Hz, data below this threshold will not be used for real-time processing.
E6/B3: Only available, if the Enable SNR filtering property is set to Yes. Specifies the threshold of the Signal-to-Noise ratio [in db/Hz] for code on L6 frequencies of the supported satellite systems. Default is 20 db/Hz, data below this threshold will not be used for real-time processing.
Note - The Dynamic Station Coordinate feature is only available in a Real-Time Network system with RTX license.
Dynamic station coordinates are a second set of coordinates, which are used internally by the network processor modules only. They are calculated by the Trimble Code Bias Calibration service as post-processing of stored observation data based on RTX technology.
When dynamic station coordinates are available, the GNSS Receiver modules provide them to those Synchronizer modules, for which these GNSS Receiver modules are selected. The GNSS Receiver Dynamic Station Coordinates module view displays the difference between the entered station coordinate and the dynamically calculated one.
Station-dependent code bias calibration files are a further product of the Trimble Code Bias Calibration service. They are also based on the calculation of offsets to known coordinates.
For making use of dynamic station coordinates make sure to set up the system as follows:
Tip - For more information on dynamic station coordinates, see the description of the GNSS Receiver Dynamic Station Coordinates view. For more information of the station-dependent code bias calibrations, see the description of the Code Bias Calibration module.
Compute dynamic station coordinates: By default set to No. Set the property to Yes for both, the calculation of dynamic station coordinates and of station-dependent calibration files.
3-s 2D outlier detection: Only available if the Compute dynamic station coordinates property is set to Yes. One of two settings used for the detection of outliers. Specifies the maximum 3-s threshold in plane, which must be met by a post-processing solution to be considered reliable.
3-s Height outlier detection: Only available if the Compute dynamic station coordinates property is set to Yes. One of two settings used for the detection of outliers. Specifies the maximum 3-s threshold in height, which must be met by a post-processing solution to be considered reliable.
Offset 2D position change detection: Only available if the Compute dynamic station coordinates property is set to Yes. One of two settings used for the determination of whether a dynamic station coordinate should be updated. Specifies the a position change in plane, which must be met by a post-processing solution to be considered a candidate for position update.
Offset Height position change detection: Only available if the Compute dynamic station coordinates property is set to Yes. One of two settings used for the determination of whether a dynamic station coordinate should be updated. Specifies the a minimum position change in height, which must be met by a post-processing solution to be considered a candidate for position update.
Max age selected position: Only available if the Compute dynamic station coordinates property is set to Yes. Determines how long a dynamic station coordinate is used as current position if the Code Bias Calibration module does not provide a new post-processing solution. Thereafter, the GNSS Receiver module stops using DSC so it does not provide coordinates to the network processors and will be in alarm status.
