Unleashing Precision: Understanding RTK and the Superiority of Drone-Mounted RTK modules

Updated: Aug 17, 2023

In recent years, the rapid advancement of technology has revolutionized the way various industries operate. One such innovation is the use of drones with Real-Time Kinematic (RTK) capabilities, offering unparalleled accuracy in positioning and data collection. In this blog post, we will explore what a drone with RTK means in terms of accuracy, why the Earth Mapper's DJI Mavic 3E RTK stands out as a superior option, and how construction companies can leverage this cutting-edge technology to gain a significant advantage in their operations.

What is a Drone with RTK?

A drone equipped with Real-Time Kinematic technology is designed to provide precise and centimeter-level accuracy in positioning, navigation, and data collection. Traditional consumer-grade drones rely on Global Positioning System (GPS) for location determination, which typically offers an accuracy of a few meters. However, RTK-enabled drones take accuracy to an entirely new level by integrating GPS with a real-time correctional system.

The RTK system involves a drone-mounted RTK module or a base station that communicates with the drone, sending real-time corrections to its GPS data, greatly reducing the errors caused by atmospheric disturbances and satellite signal delays. This continuous stream of corrections ensures that the drone's positioning remains precise, even in challenging environments such as urban canyons or construction sites with obstacles.

DJI Mavic 3E RTK - The Epitome of Accuracy

Among the various RTK-enabled drones available in the market, the DJI Mavic 3E RTK stands out as a game-changer. DJI, renowned for its drone technology, has engineered the Mavic 3E RTK to offer unbeatable accuracy and performance.

1. Sub-Centimeter Accuracy: The Mavic 3E RTK boasts sub-centimeter level accuracy, which means it can pinpoint locations with incredible precision. This accuracy is critical for construction projects that require precise measurements for surveying, mapping, and monitoring progress.

2. Reliable RTK System: DJI's Mavic 3E RTK incorporates a robust RTK system that efficiently communicates with the base station, ensuring that corrections are consistently applied to the drone's GPS data. This eliminates the need for post-processing, saving time and effort in data analysis.

3. Advanced Obstacle Avoidance: Construction sites are often cluttered with obstacles and structures, making navigation challenging. The Mavic 3E RTK is equipped with advanced obstacle avoidance sensors, ensuring safe and reliable flight even in complex environments.

Advantages for Construction Companies

Construction companies can significantly benefit from using drones with RTK capabilities, particularly the DJI Mavic 3E RTK. Here's how:

1. Enhanced Surveying and Mapping: Accurate surveying and mapping are fundamental to any construction project. With sub-centimeter accuracy, the Mavic 3E RTK can rapidly capture precise topographic data, generating detailed 2D maps and 3D models of construction sites. This information aids in better project planning and design, reducing the risk of errors and cost overruns.

2. Efficient Earthwork and Volumetric Analysis: Calculating earthwork volumes accurately is essential for optimizing resources and materials. Drones with RTK enable construction companies to perform volumetric analysis with unmatched precision, making it easier to monitor material stockpiles, track progress, and ensure efficient resource allocation.

3. Construction Site Monitoring and Inspections: Drones equipped with RTK allow for real-time monitoring of construction sites. Construction companies can conduct aerial inspections regularly, identifying potential safety hazards, tracking construction progress, and making informed decisions promptly.

4. Cost and Time Savings: The high accuracy and efficiency provided by the Mavic 3E RTK can lead to substantial cost and time savings for construction projects. Minimized rework, optimized resource allocation, and streamlined data collection all contribute to better project outcomes.


Drone technology, particularly those with RTK capabilities, has revolutionized the way construction companies operate. The DJI Mavic 3E RTK stands out as an exemplary drone, offering sub-centimeter accuracy and a reliable RTK system. Construction companies embracing this advanced technology can benefit from enhanced surveying, improved project planning, efficient site monitoring, and significant cost and time savings. As RTK-enabled drones continue to evolve, we can expect even more accurate, efficient, and seamless integration into construction workflows, further revolutionizing the industry's future.
