Single Point Positioning

For the determination of a rough receiver position and of its plausibility, do the following:

• From the GNSS Receiver shortcut menu, select Single Point Position.

  GNSS Receiver module computes a Single Point Position averaged from the next 10 incoming epochs. Simultaneously, it opens the Single Point Position: <Station Code> dialog and there displays the SPP coordinates, the offset to the currently stored coordinates, and for X,Y,Z the 3-s standard deviation values as quality indicator.

• You can repeat this calculation any time. At the Single Point Position: <Station Code> dialog, click Start New SPP Calculation. The dialog can stay open (and can be docked to the main window), even if you move to another module in the mean time.

For replacing the stored station coordinates by the ones determined by single point positioning, do the following:

• From the Single Point Position: <Station Code> dialog, click Apply.

Warning - Applying the SPP results to the station which is used by this GNSS Receiver module updates the coordinates for the whole Trimble 4D Control Server system. All modules using the station positions for calculations will reset the calculation of the baselines or stations to which new coordinates are applied.
