GNSS Tab: setting Antenna Offset
The Altus NR3 automatically compensates for the Antenna Phase Centre offset using the
approved calibration of the product in order to provide the most accurate position out of the
box.
The slant height measuring point (SHMP) is located at the line formed by the transition from
the orange to gray plastic. The vertical offset from the SHMP to the Antenna Reference Point
(ARP) at the bottom of the antenna is 35mm.
