Yuneec recently announced that their H520 hexacopter will now be available with an RTK (Real Time Kinematic) system, provided by the Swiss company Fixposition.
According to Yuneec, the RTK system will ensure maximum precision for mapping and inspections. The RTK integrated satellite navigation allows for centimeter-precise positioning, with accurate recurring images and faster 3D mapping. This increased reliability will benefit drone operators flying in tricky GPS conditions, such as in cities or canyons.
Benefits of the RTK System
RTK
systems help support commercial drone applications that require maximum
precision. By using RTK technology, the H520 will now be able to fly
closer to objects for inspection, thus resulting in the collection of
more precise data.

How much closer? According to Yuneec, while the H520 can currently fly within the meter range for inspections without the RTK, with the RTK it will be able to fly within the centimeter range (1 cm + ppm horizontal / 1.5 cm + ppm vertical).
This improvement in accuracy is most important in those applications where several images need to be taken at the same location on different days. Some examples of these kinds of scenarios include:
- Documenting progress on construction sites
- Inspecting mountain landscapes to prevent natural hazards, such as rock falls or avalanches
- Forensic accident scene reconstruction
The RTK satellite navigation system also makes it possible to significantly reduce image overlaps, which means fewer photos, shorter model calculation times, and maximizing efficiency in workflows.
The H520 RTK system is fully integrated into both the hardware and the software of the H520, so that drone pilots can retain the functionality of Yuneec’s DataPilot software for mission planning and other key operations.
The system works with two components—the RTK module on board the H520 and a base station on the ground. For precise navigation, the module supports constellations of up to three different satellite systems from GPS, GLONASS, Galileo and BeiDou.
If the use of a ground station isn’t possible, the system can also be operated with a national reference station network (network RTK). The network RTK is provided by third-party providers and requires an internet connection, such as a mobile hotspot. All data, including satellite data, is recorded, making the H520 RTK a good option for post processed kinematics (PPK).
About the Yuneec H520
The Yuneec H520 was first unveiled at CES 2017. Since then it has held a solid position in the drone industry as a reliable professional drone at a reasonable price point. (The H520 is currently on sale for about $1,800.)
