To change the antenna or prism height during an integrated survey

To change the GNSS antenna height during an integrated survey you must change the current target height. The GNSS antenna height is computed automatically using the Prism to antenna offset configured in the IS style.

1. Make sure you have selected the correct prism type. In the Prism to antenna offset field, tap and select the prism type. The Prism to antenna offset field is automatically populated with the correct offset value for the selected prism. For details on the prism to antenna offset value for each prism type see Prism to antenna offset values for standard prisms.

   If an incorrect antenna measurement method is set, the incorrect offset is applied to the GNSS antenna heights. Make sure the correct position is selected in the Measured to field for the antenna in the Rover options form of the GNSS survey style referenced by the integrated survey style. For R980, R12i, R12, and R10 receivers, the offset is from the center of the prism to the bottom of the quick release. For other receivers, the offset is from the center of the prism to the bottom of the antenna mount.

2. Tap the target icon in the status bar and select the appropriate target.

3. Enter the Target height (the height to the center of the prism).

   The updated height is not displayed in the status bar until the target form is closed.

4. To see the entered target height, the prism to antenna offset configured in the survey style, and computed antenna height, tap Antenna.
5. Tap Accept.
