Single Point Position: <Station Code> dialog

This dialog appears if you do the following:

1. In the Tree view, go to the GNSS Receiver item.
2. Open the shortcut menu and select Single Point Position.

The dialog displays the station code of the station for which it applies in its header. This dialog can be docked to the main view or to other dialogs and it can stay open, even if you move the focus to other modules or main menu items.

Use the Single Point Position <Station Code> dialog to view the current SPP offsets to the known station coordinates, to recalculate the SPP, and to apply it if no better coordinates are available for the station.

For each GNSS Receiver module, only one Single Point Position <Station Code> dialog can be opened in a Trimble 4D Control Server UI. If you move a GNSS Receiver module to another Container, its Single Point Position <Station Code> dialog closes automatically. If you have closed the Trimble 4D Control Server UI with one or several of these dialogs open, they do not reappear automatically, when you restart the UI.

Status display field

Displays current status messages. For example, it displays how many epochs out of 10 have already been processed and added to the averaged SPP. With each new epoch processed, the values for the current epoch are updated in the Coordinates table.

Select New SPP Calculation button

Repeats the SPP calculation with the next 10 incoming epochs. The Status field displays the current status of the recalculation.

Coordinates in <Reference Frame> current epoch (table)

For each coordinate, the table displays the known position as stored in the global station list, the current offset to it, the coordinate resulting from the SPP (SPP result), and its 3-s standard deviation value as a quality and plausibility indicator. If you change the current known station coordinates manually using the System Properties or another Trimble 4D Control Server UI in the distributed system, the table content (current position, offset) is updated automatically.

Apply button

Click the Apply button to replace the current known position coordinates of the station mentioned in the dialog header by the current SPP average.

Note - All modules using the station positions for calculations will reset the calculation of the baselines or stations to which new coordinates are applied. In a real-time network approach, the Network Motion Engine, the RTXNet Processor, and the Network Processor will reset baseline estimation for all baselines connecting the respective station to any other station.

Close button

Click the Close button to close the dialog without applying the Single Point Position to the station.
