Our Story


Founded in 2020, Drone Pros was born to revolutionize how businesses approach project planning, management, and marketing. Our founder, Grant Fuellenbach, recognized the untapped potential of drone technology in these industries and set out to create a company that would deliver high-quality, innovative, and reliable aerial solutions to clients across Denver and beyond.

Since our inception, we have grown into a trusted partner for countless professionals, offering our services to real estate agents, architects, engineers, and construction project managers. We have successfully completed numerous projects, each time surpassing client expectations and reinforcing our commitment to excellence.

  • Improvise; Adapt, Overcome 🚀

  • Stay Consistent; Stay Safe 🚀

The Mission

Drone Pros is committed to helping the FAA improve drone flight safety with every mission. Transparency is paramount when you work with a Drone Pro. Beyond Preflight Checklists and Reports, every Pro that you work with shows you their flight count and number of hours directly in their email signature. See mine below.


We educate ourselves and assist our pilot network with video libraries, tutorials, and coursework. We strive to ensure that our mission aligns with, and promotes, the desired outcomes of the FAA, public safety personnel, client requirements, and the drone community.

Through checks & balances and group accountability, we continue to meet our commitments to our pilot network, clients, and our partners.

Using Custom Built Drones that weigh less than an lb and virtual headsets, we can fly safely and securely through homes, condos, offices, warehouses, and other commercial buildings.

At Drone Pros, we provide cutting-edge drone solutions tailored to the needs of project managers and supervisors in real estate, excavation, land development, construction, engineering, and architecture. Our advanced LiDAR and photogrammetry technology delivers high-quality data, accurate measurements, and detailed imagery to streamline your operations and drive project success.

Process Stage
7. Quality Checks

Finally, the pilot will check the results for accuracy and quality. This usually involves comparing a subset of coordinates from the processed drone data with the same points measured independently with the GNSS receiver (commonly referred to as check points). 

  • If the results are within the required tolerances, the scan can be considered complete. If not, some troubleshooting and potentially additional data collection might be needed.

This process enables the team to acquire highly accurate and precise spatial data from a drone scan, which can be used for a wide variety of applications in GIS, construction, and other fields.

6. Post-Processing Work:

After completing the drone flight, the pilot will transfer the images and the RTK/PPK data to a computer and more specifically, the pre-determined photogrammetry software for the project. Having ensured the GCPs are properly identified and utilized to georeference the data, the software will generate a point cloud, digital surface model, or other deliverables as required by the project.

5. Conducting the Flight:

Executing the flight plan, the drone pilot will ensure the drone maintains a consistent altitude and speed, and overlaps images sufficiently to allow for accurate photogrammetric processing (typically around 75-90% forward overlap and 65-85% side overlap). All the while, monitoring the drone's status and the data collection process throughout the flight.

4. Setting up the Drone and Aerial Equipment:

Now, setting up the drone, the team will ensure that the RTK (Real-Time  Kinematic) or PPK (Post-Processed Kinematic) system and the camera ,or other sensors, are correctly configured. If using an RTK system, the trained pilot will ensure the base station is properly set up and that there is good communication between the base station and the drone.

3. Conduct a GNSS Site-Scan of GCPs:

Using a GNSS receiver, the certified team member will scan in each GCP. Record the precise coordinates of each GCP, ensures that the GNSS receiver has a clear view of the sky and has collected an adequate amount of data for each point.

2. Set up Ground Control Points (GCPs):

The Drone Pros team will arrive On-Site and place highly visible GCPs throughout the site. These are known locations that are scanned in using a high-accuracy GNSS receiver. They serve as reference points to accurately georeference the drone data. The number and distribution of GCPs will depend on the size and complexity of the site, but they should be evenly distributed and visible from the air.

1. Preliminary Assessment and Planning:

First, the Drone Pros will need to understand the project's needs and specifications. This includes the site's size, the level of accuracy required, and any obstacles that might pose a safety risk or affect data quality. From this information, the team can develop a flight plan. While also checking local regulations and ensure all permissions and permits are in place.
