With the combination of integrated RTK support and a base station (not included), the H520E drone is capable of centimeter-level accuracy in flight; specifically within 1cm horizontally and 2cm vertically. This precision can help in a multitude of ways. You can perform flights that are closer to structures for more detailed inspections. You can fly to very specific locations to take the same photo over time to track changes in the environment or landscape. Mapping can become extremely precise and requires fewer overlapping photos to create, which equates to faster missions and preserved battery life.

The RTK system is engineered to provide this kind of accuracy in as little as 30 seconds, even under challenging GPS conditions. If you'd like, you can utilize RTK functionality without a base station over a network RTK reference station, which would require an internet connection and a 3rd-party provider that could result in additional fees.

If GPS signal conditions are so bad that RTK usage is not possible, you can also use the H520E RTK drone for PPK (Post-Processed Kinematics). As its name implies, PPK uses the raw GNSS data stored onboard the drone via YUNEEC's DataPilot to make corrections and provide precise results after the flight is completed. Additional RTK features of this drone include a 5 Hz update rate of position, velocity, and time, and support for GPS, GLONASS, Galileo, and BeiDou GNSS constellations.

Since the applications of the H520E are meant to record sensitive personal information, industry secrets, and evidence in ongoing investigations; it's essential that this information is kept secure. This is why YUNEEC engineered a closed system, where any recorded information is only shared between the drone, payload, and controller. Nothing is sent to YUNEEC or other 3rd-party servers during flight, and all log files of flown missions are only stored within the drone itself.

Powered by an Intel quad-core processor with OFDM support and an Android-based operating system, the ST16E allows for piloting miles away from the action. Thanks to live image reception from up to 1.2 miles away (up to 3.8 with OFDM) on its built-in 7" touchscreen, it will still feel as if you're there. As you fly, real-time telemetry is displayed, such as altitude, speed, distance from home, GPS position, and battery status. It also offers automatic and manual imaging control of video resolution, white balance, white light exposure, ISO, and shutter speed.

At the heart of every mission is YUNEEC's DataPilot software. It's installed into the ST16E remote and is also PC/Mac compatible. You can use it to plan waypoint and survey missions, create orthomaps, 3D scans, and crop data imagery in the field or pre-flight on a desktop. Additional features include creating construction site measurements, BIM components, accident reconstruction, and photo stitches.

With user-defined frontlap/sidelap, pilots can auto-generate survey paths and cross-hatching for 3D and large-format image output. If you're in an area with no connectivity, created and premade maps with waypoints can be stored/cached for access in the field. When missions need to be repeated, such as with inspections, flights can be stored for later recall. Missions made with DataPilot can be transferred to the ST16E via email, thumb drive, or microSD card.
