2.8 G6N ARP
The Antenna Reference Point (ARP) is at the bottom of the G6N. The Antenna Code is TIAPENG6.
Figure 7: G6 Dimensions
2.9 Antenna Height
When using the G6N as a Rover, the antenna height is the vertical height of the survey pole. This is direct to the ARP, so no offsets are
required for a vertical survey pole.
For a Slant Height, a Slant Height Adapter is supplied to allow a convenient measurement around a tripod or tribrach.
Figure 8: Slant Height Adapter
