DJI DJI Phantom 4 TEO
RTK PPK AGNSS L1 / L2

The best solution for surveying
using UAVs based on GNSS board L1 / l2

RTK | PPK solution based on DJI Phantom 4 adv | pro

The best topodrone is THEODRONE!
The world's first serial geodesy quadrocopter with AShot sync module and GNSS board AGNSS L1 / L2, designed specifically for DJI Phantom 4 adv / pro.

The quadcopter control interface is simple and intuitive.
The flight time of the quadrocopter is up to 26 minutes, which allows you to perform a significant amount of AFS in one take-off: 90 hectares at 4.5 cm / pixel or 10 p.km.
Up to 2250 hectares per 1 light day, which is a record indicator in this class of geodesic quadrocopters.

Thanks to the built-in GNSS L1 / L2 receiver, in the process of work, you can almost completely abandon the ground signs for snapshots - 1 identification is required to calibrate the camera focus (to specify the height).
Thanks to the camera shutter synchronization module - AShot , which without delay transmits a photo tag to the GNSS L1 / L2 board, it is possible to obtain the exact coordinates of the centers of photographs (up to 2 cm).

The final accuracy of the digital terrain model using one ground identification mark is 2-5 cm in plan and up to 7 cm in height at a flight height of 150 meters and a speed of up to 10 m / s, which gives a resolution of 4.5 cm / pixel.

 

ADVANTAGES

DJI PHANTOM 4 TEO PPK

Camera 20 megapixels
Flight time up to 26 minutes
Fast flight preparation time
10 p.km for 1 flight or 90 ha at 4.5 cm / pixel

 

CAMERA CALIBRATION

The cameras in our survey drones do not need calibration. With AFS, it is sufficient to use 1 identification mark, according to which Auto Calibration is performed in photogrammetric software.
An example of such a calibration can be seen in this video:

INTEGRATED GNSS BOARD AGNSS L2

Supports GPS, GLONASS, BeiDou, Galileo.
L1 / L2 GNSS board specially designed for DJI Phantom 4 adv / pro
GPS + Glonass recording frequency up to 15 Hz!
Download data with measurements over Wi-Fi.
Built-in memory of 16 GB.
Ability to work from reference base stations within a radius of 80 km.

 

ASHOT MODULE

Transferring a photo tag to the GNSS board without delay, strictly in the middle of the shutter speed of the photo - this allows you to use the results of the AFS with only one sign for height calibration.
The photographing interval is 1.3 and 1.8 seconds.
Eliminates omissions of photographs and, as a result, eliminates "white" spots during processing.

 

DETACHABLE GNSS ANTENNA AND TEOBOARD

A helical, highly sensitive, geodetic GNSS L1 / L2 antenna was used, installed in the center of the quadrocopter.
Together with the TEOBOARD distribution board, it became possible to receive a high-quality GNSS signal in any weather and time of day.

 

BUILT-IN RADIO BEACON TIGROMUH

Provides easy quadrocopter search in case of emergency or crash.
Activation of the beacon on call from the VHF radio.
Voice transmission of the lighthouse by voice to the VHF radio.

 

TEOBOARD

GNSS signal distribution board from helical antenna to GNSS board and DJI flight controller. A unique solution that allows you to have a constant high-quality signal from the GPS, GLONASS, BEIDOU, GALILEO satellite constellations.

P
oluchayte quality RAW satellite measurement data is always, regardless of the weather and time of day!
