See To change the antenna or prism height during an integrated survey. Trimble AG25 This folder contains a file called antennas.xml, which defines the antennas supported by Trimble software; and it contains at least two ANTEX (.atx) files, which provide absolute, elevation and azimuth dependent antenna corrections. A new reference system, IGS20, was released on 2 October 2022, replacing the previous IGS14 reference system.
