# Prism to antenna offset values for standard prisms

In an integrated survey the software automatically adds the appropriate Prism to antenna offset value in the integrated survey style when you tap next to the Prism to antenna offset field and select the prism type. For reference purposes the offset values and measurement method used for the offset value are provided below.

When performing an integrated survey, the method used to measure the prism to antenna offset value depends on the receiver:

- For 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.

Prism type | Offset value
--- | ---
Trimble 360° | 0.034 m
VX/S Series MultiTrack | 0.034 m
VX/S Series 360° | 0.057 m
Spectra Precision 360° | 0.057 m
R10 360° | 0.028 m
Active Track 360 | 0.095 m
Spectra Geospatial 360° | 0.034 m
Spectra Precision 360° | 0.057 m

Because the Trimble Precise Active target is not a 360 degree target it cannot be used in an integrated survey.
