What are the Phase Centre values of the V560 antenna?

The V560 antenna has two sets of phase centre values; one for L1 and one for L2 GNSS frequencies.

The diagram below shows the Antenna Reference Point (ARP) from which the phase centre values are measured.  It also shows the V560 vertical (Up) phase centre values for the GNSS L1 and L2 frequencies:

The below diagram shows the ARP at the antenna base and the antenna North alignment reference:

The main phase centre offset component is the vertical (Up) but there are also small horizontal offsets (North and East) that can be applied. 

The table below details the North, East and Up phase centre values for the GNSS L1 and L2 frequencies:

If required the V560 Antex file is available below. This file contains the offset parameters used to obtain highly accurate values when post-processing.
