Antenna height is not always the height of the GPS rod
Here you have to pay attention because the height of antenna is not always the same as the height of the rod. Some GNSS receivers have an ARP that is not equal to 0. The ARP is the Antenna Reference Point. It is normally the distance between the antenna in the GNSS receiver and the bottom of the GNSS receiver. Some GNSS receivers calculate the position of the bottom of the GNSS receiver.
For more info on the ARP of your GNSS receiver check with the dealer of your GNSS receiver.
Let’s continue the tutorial of changing the antenna height
After changing the height you can click on the ‘OK’-button.

There is only one different. The height behind the icon of the antenna height is different. It is the same as the value that you filled in before.
Now it is only a matter of confirming the value. To do this you click the ‘OK‘-button.
This takes you back to the main screen of Apglos Survey Wizard. On that screen you see that the antenna height is different. It is now the value that you filled in.
Apglos Survey Wizard uses this value now to determine the exact height of the bottom of your GPS rod.
