PX4 ground control software that DRT designed from start to finish.From the pre-flight check to the post-landing records, you operate it the same way on an Android controller and a Windows PC.
General-purpose ground control software is made for developers, so all information comes at once.DRTView shows the operator only what is necessary now, and keeps the developer tools one step further in.
DRTView is the main screen of the controller.Vehicle link, video reception, and battery and satellite status are laid out on one screen. You confirm the pre-arm check results from the aircraft, and one button starts the flight.
Home screen · Link status · Battery · Satellites · Pre-arm check · Flight screen button
Built-in guide · From the arming procedure to warning response, on the controller
Flight screen layout · A guide where you tap an element to learn it
Flight screen
Only what you need, over the video.
Low-latency video
Our own video pipeline draws H.264 and H.265 video.
Eyes on the aircraft
Altitude, flight time, battery and thrust sit in order at the edges of the screen.
Gimbal · Camera · Recording
Control them on the same screen, and original-quality recording is one button.
Safety
Danger arrives first, on screen and by sound.
Obstacle distance display
Distances the aircraft detects, drawn over the video as a ribbon per direction with a forward readout
Warning popups
Aircraft faults and operating limit violations shown at once as a banner
Voice alerts
In Korean, English or Japanese voice, even when you cannot look at the screen
Thrust load monitor
Total weight estimated from thrust, with a descent advisory when it exceeds the propulsion table
Link loss handling
The last values are frozen, and when the same aircraft returns, the app continues automatically
Forward obstacle distance ribbon and direction radar
Live position and the path flown stay on the map.No-fly and controlled airspace are color coded, so you can decide in the app whether you can fly, without other sources.
Main map · The path flown stays as a track, and video shows as PIP
No-fly zones are color coded on the map.
Long-press to see the zone name and class at once.
Difference from general-purpose ground control software
Made for operators.
When you fly the same PX4 aircraft with general-purpose open-source ground control software and with DRTView, the operator sees this much difference.

Screen
All items come at once on one screen.
Only what is necessary now, with developer tools one step further in.
Warnings
English codes and short phrases appear.
Korean sentences and voice, including what to do.
Before arming
You must search the logs to find why it does not arm.
The check results on the home screen show each item.
Map
It depends on online maps.
Color-coded airspace, saved maps and our own aerial imagery, even on closed networks.
DRT aircraft
Dedicated equipment and mission features are not available.
It recognizes NEXA1 and DRT Q automatically and opens the screens and features for each aircraft.
Field tools
Features grew in the field.
New version notice on the home screen · Update with one tap
Remote updates
The app and the aircraft parameters stay current with only an internet connection.
Automatic flight records
Telemetry records stay on the controller and upload to the server as the basis for remote diagnosis.
One-touch recording
Video is saved at original quality without re-encoding and plays back on the controller at once.
Flight log download
Download the aircraft flight logs to the controller for analysis and maintenance decisions.
Controller setup
A wizard guides stick calibration and channel and function assignment. Joysticks work the same way.
Settings
Simple to start, precise to the end.
Each aircraft has its own quick setup. For DRT Q, you choose presets and response curves in the feel editor.Go deeper, and all of the more than 1,000 PX4 parameters open with groups and search. You compare the values that change before you apply them, and test motors and servos one by one.
Optimized for DRT aircraft, complete for standard aircraft too.
DRT aircraft
Our own aircraft, such as NEXA1 and DRT Q, are integrated down to dedicated hardware, mission features and per-aircraft settings screens.
Standard PX4 aircraft
It connects over USB, UDP, TCP and Bluetooth. When you connect several links at the same time, the primary link changes automatically, and MAVLink signing protects control commands.
Android controllers
It runs on Android controllers and tablets such as MK15, RC7 and UniRC 7.
Languages
In three languages, at any site.
It supports Korean, English and Japanese. As an in-house app, every screen is tuned for each language, and we add new languages on partner request.
Korean
It is the default language. Warnings and voice prompts use field terminology.
English
It supports overseas operation and exported equipment.
日本語
It supports the Japanese market and the operations of local partners.
DRTView for Windows
On a desk, see it wider.
On a Windows PC, the same app works for a large screen and a mouse.Draw a flight plan on the map and send it, use aerial imagery files as the map at sites without internet, and command several aircraft from one screen.
Flight planning
Place waypoints, loiters and points of interest on the map, and generate survey, corridor and structure scan patterns automatically.
Local maps
Load and stitch GeoTIFF aerial imagery, and save satellite and label maps in advance for use without internet.
Fleet command
Lay out the status of several aircraft on one screen, and command one aircraft or all of them.
Releases ship after developer builds are tested on real aircraft, and the Android controller and the Windows PC are maintained in the same flow. These are the changes in the three most recent releases.
