How tall is the device set at the 360 degree prism and with the gps antenna on top?

The prism height is 11 cm, its center is 5 cm from the base. when changing the height of the GPS it also changes from the prism. do I add that I only have to insert the prism height?

It's a hybrid system from Topcon.

Thank you.

  • Hi Tomus

    All depends by the field software are You using.

    If it can consider the prism offset, the antenna/prism height is automatically calculated respect the rod reading.

    So, when you set the antenna height , pay attention to the "offset prism" checkbox.

    This is a sample from Magnet:
