What to buy

Filter
An ND filter set made for the DJI Phantom 4 RTK
The lens is fixed, so an ND filter is the only way to hold the shutter near 1/50 second in daylight. Buy the set cut for this model, because a filter for another one will not seat.
Battery
A DJI Phantom 4 RTK Intelligent Flight Battery, 5870 mAh
One battery runs 30 minutes. A spare is the difference between one flight and a whole session.
Card
MicroSD, Max Capacity: 128 GB. Class 10 or UHS-1 rating required Write speed≥15 MB/s
The DJI Phantom 4 RTK carries no storage of its own. Without a card it records nothing at all.

- Hover Accuracy Range
RTK enabled and functioning properly：Vertical：±0.1 m；Horizontal：±0.1 m RTK disabledVertical：±0.1 m（with vision positioning ）；±0.5 m（with GNSS positioning）Horizontal：±0.3 m（with vision positioning）;±1.5 m（with GNSS positioning）
- 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.
GNSS
- Single-Frequency, High-Sensitivity GNSS Module
GPS+BeiDou+Galileo（Asia)；GPS+GLONASS+Galileo（other regions）
- Multi-Frequency Multi-System High-Precision RTK GNSS
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.
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)
- Data Acquisition Efficiency
Max operating area of approx. 1 km² for a single flight(at an altitude of 182 m, i.e., GSD is approx. 5 cm/pixel, meeting the requirements of the ASPRS Accuracy Standards for Digital Orthophotos Class Ⅲ
