Propeller AeroPoint Ground Control Points for Drone Mapping

Propeller AeroPoint Ground Control Points for Drone Mapping

AeroPoints Ground Control Points are high-precision, smart ground control points, thoughtfully designed for drone beginners, but precise enough for survey veterans. Forget hours with bases and rovers, just lay out your AeroPoints and let them do the work.

Use AeroPoints Ground Control Points anywhere and with any coordinate system

Durable, lightweight design

Forget complex surveying equipment and prevent human error with these durable, lightweight ground control points.

One-button operation

One-button operation means you don’t need to be a GPS expert to use them. Just lay them out, and they’ll do their job.

Wireless upload

AeroPoints upload their ground control data wirelessly to your user portal from wherever you are. Never worry about processing your data again.

Mobile app-based management

A dedicated AeroPoints app delivers real-time diagnostics about your ground control hardware and makes configuration setup a breeze.



The Propeller AeroPoint Ground Control Points for Drone Mapping are built for beginners and validated by experts. AeroPoints are the industry’s only smart ground control points. Use it with any drone and on any worksite to capture survey-grade data every time you fly.

How AeroPoints work

Each AeroPoint includes a solar panel and plug-in charger, battery, GPS, and Wi-Fi inside a fully-sealed, lightweight shell. The real value of AeroPoints comes from their flexibility—use them for ground control, checkpoints, or even as a base station.

There’s no more need for awkward and expensive survey gear. You can show up on-site, quickly disperse the AeroPoints, and then fly.

Calibrate your AeroPoints with a permanent survey mark, including State Marks, by placing an AeroPoint over it and uploading the mark’s position with your data.

Sites with a base station

Ensure your drone data has the same reference point as your other data by importing a RINEX file with your AeroPoints. Great for construction sites with machine control.

Sites with a local grid

Align drone data with machine control, design, and other site data by uploading your Trimble or Topcon calibration file to calibrate AeroPoints with your local grid coordinates.

Fully Automated Processing In Propeller Corrections Network Coverage Areas

Aero Points Ground Control automated processing is the simplest way to use Aero Points Ground Control Points on your site. It ensures a standard 24-hour turnaround time and preserves the efficiency benefits that these smart GCPs provide on your drone survey.

If you’re within the Network, choose the Propeller Corrections Network during your dataset upload and we will take care of the rest. There is no need for sending in supporting data or spreadsheets.

Using an Aero Point as a Base Station on a Known Mark

You might also be working on a site with its own calibration. If you are using local coordinates, we recommend using your AeroPoint on a known mark.


Simply place an AeroPoints Ground Control Points on a known survey mark or benchmark location in your survey area. Be sure to place this AeroPoint first, and pick it up last. This allows it to record data for the duration of your flight. Propeller then used this AeroPoint, combined with the known coordinates of the mark it was sitting on, as the reference point for the other AeroPoints used in the survey.


Using an Aero Point to Create a New Known Mark

If you don’t have the option of using the Network or there aren’t known marks available, the global accuracy of your survey will be reduced.  But you can still use AeroPoints to get results that are internally accurate and consistent over time.

To use this method: Find a hard, flat surface that won’t move or be disturbed, and establish your own “mark.” (We recommend using heavy-duty spray paint like that used for line marking.) Place one AeroPoint at this mark and ensure it is left in place to record at least two hours of data.

For your first drone survey, we’ll use the data from this AeroPoint to calculate an estimated point. Then when you fly your site again, we’ll treat that coordinate as a “known mark.”

Using Your RINEX Corrections

Should you have access to a dual frequency L1/L2 RTK rover or your site has an RTK base station receiver, you can provide us with RINEX formatted GNSS observations for the period of your survey. We then use that as the reference point.

This RINEX file must have an accurate location for the base in the header, as this is the location that the AeroPoints will be measured against. To properly process your data, we need RINEX version 2.11 with a minimum frequency of one observation every 10 seconds. It must cover the whole period of the drone survey and have no gaps longer than 10 minutes.
