Total GNSS antenna height includes the following:

1. The height of your surveying range pole
2. The height of any accessories that holds your antenna on top of your range pole
3. The height of your antenna phase center

Calculating the Antenna Height for Arrow Users:

If you are using an Arrow Series® GNSS receiver, you will need to add the following two values:

1. The height of your range pole (check with your manufacturer or measure it if you are not sure)
2. The height of the antenna plate
3. The antenna phase center

To calculate these values, choose one of the following articles based on your Arrow model:

Arrow Gold+™, Arrow Gold®, or Arrow 200®: Click here.

Arrow 100®, Arrow 100+™: Click here. Note it is uncommon for a user to be using Arrow 100 or Arrow 100+ receivers with RTK.

Calculating the Antenna Height for Skadi Users:

If you are using a Skadi Series™ GNSS receiver, you will not enter a total antenna height but rather the pole height plus the height of the Skadi pole cradle assembly. The antenna phase center will automatically be added to this value to determine your total antenna height. To summarize, you need to add to the following:

1. The height of your surveying range pole height (check with your manufacturer or measure the pole to determine its exact height)
2. The height of the Pole Mounting Cradle Assembly for Skadi Series, which is .037 meters

For instance, if you are using a two-meter range pole that is exactly two meters tall, your calculation would equal this:

Range Pole Height (2.000 m) + Cradle Assembly Height (.037 m)

More information can be found in the Skadi Tilt Compensation User Manual. Even if you are not using Skadi Tilt Compensation, Skadi users may follow this portion of the manual.

Important Note for Skadi and Arrow Users as of 2025:

If you are using Eos Tools Pro on Android™ (any version) or Eos Tools Pro on iOS® version 4.0 or later, Eos Tools Pro is now able to handle the antenna height for both Arrow Series and Skadi Series GNSS receivers. Previously, iOS users might have used ArcGIS Field Maps. Arrow users may continue to use ArcGIS Field Maps if they choose, but Skadi users must use Eos Tools Pro to have the correct elevation. Skadi Tilt Compensation will not work if your antenna height is set in ArcGIS Field Maps rather than Eos Tools Pro.

Suggested FAQs:

Should I set antenna height in Eos Tools Pro or my third-party data-collection app?

Where do I set the antenna height in Eos Tools Pro?
