Why do I need antenna type?
The antenna phase centers are located somewhere around here.
The Antenna Reference Point (ARP) is almost always located in the center of the bottom surface of the antenna.
The antenna offsets are the distance between the phase centers and the ARP
If the user selects NONE as the antenna type, the offsets are set to 0.000 and the antenna phase center becomes the reference
The user does not need to know these offsets. They are passed to the processing software through the antenna type
Incorrect or missing antenna type ? big vertical errors
