DJI Phantom 4 RTK Dronas

DJI Enterprise serijos dronas - Phantom 4 RTK, puikiai tinkantis  3D modelių kūrimui, žemės tūrių, plotų matavimui, geodezijos darbams. Dėl naujos kartos sistemų matavimo duomenys realiu laiku gaunami centimetrų tikslumu. Užtikrintas skrydžio signalas ir stabilumas net ir tose vietovėse, kuriuose daug signalo trukdžių. Valdymo pultas su pritvirtintu ryškiu ekranu. [embed]https://www.youtube.com/watch?v=lxNDTaA2_hM[/embed]

Image Position Offset	The position of the camera center is relative to the phase center of the onboard D-RTK antenna under the aircraft body's axis:(36, 0, and 192 mm) already applied to the image coordinates in Exif data. The positive x, y, and z axes of the aircraft body point to the forward, rightward, and downward of the aircraft, respectively.

MAPPING FUNCTIONS

Mapping Accuracy **	Mapping accuracy meets the requirements of the ASPRS Accuracy Standards for Digital Orthophotos Class Ⅲ ** The actual accuracy depends on surrounding lighting and patterns, aircraft altitude, mapping software used, and other factors when shooting.
Ground Sample Distance(GSD)	(H/36.5) cm/pixel， H means the aircraft altitude relative to shooting scene (unit: m)

GNSS

Single-Frequency, High-Sensitivity GNSS Module	GPS+BeiDou+Galileo*（Asia)； GPS+GLONASS+Galileo*（other regions）
	Frequency Used： GPS：L1/L2； GLONASS：L1/L2； BeiDou：B1/B2； Galileo*：E1/E5aFirst-Fixed Time：< 50 sPositioning Accuracy: Vertical 1.5 cm + 1 ppm（RMS）； Horizontal 1 cm + 1 ppm（RMS） 1 ppm means the error has a 1mm increase for every 1 km of movement from the aircraft.
