FAQs GENERAL PRODUCT While previous Phantom series drones were built around professional photographers and hobbyists, the Phantom 4 RTK was designed for industrial users for high-precision mapping and other data acquisition missions. While the Phantom 4 RTK shares a similar camera and form size, it also adds a RTK positioning module, a new TimeSync system, a purpose-built mapping app and more. The Phantom 4 RTK uses the same 9450s Quick Release Propellers as the Phantom 4 Pro. No, the Phantom 4 RTK has specific versions for different countries and/or regions. Users can check the version code on the product packaging or through the GS RTK app (go to Aircraft Information -> Firmware). While the Phantom 4 RTK and Phantom 4 Pro/Advanced share the same 1-inch, 20 megapixel CMOS sensor, the Phantom 4 RTK has improved the capabilities of the camera for mapping through a new lens distortion recording process. Each Phantom 4 RTK camera goes through a calibration process that measures the distortions of the lens, and records the corresponding undistort parameters. The camera allows users to output the original images without distortion correction as well as the undistort parameters in the XMP file for post-processing Yes, the ND filters made for the Phantom 4 Pro can also be used for the Phantom 4 RTK. No, you can enable the distortion correction in the camera but the images will be less precise compared to distortion elimination in post-processing software. Each Phantom 4 RTK camera goes through a calibration process that measures the distortions of the lens, and records the corresponding undistort parameters in XMP DewarpData. When the “distortion correction” is switched off, the original image with distortion will be generated. When the “distortion correction” is switched on, the parameters used to eliminate distortion is not the parameters calibrated, but the design parameters of the camera. When eliminating the distortions, it is not done pixel by pixel. 1.Built-in 5.5-inch display, 1080P, up to 1000 nits brightness. You can see the screen in strong sunlight. The controller can work in low temperatures. FCC and CE mode switching is not available. No. The effective video transmission distance depends on your method of operation (such as the antenna position) and actual flight environment. In an open and unobscured environment, the maximum distance is 7 km when FCC compliant, and 5 km when CE compliant. (2.4 GHz). This means that improper antenna positioning is likely affecting the video transmission signal, and therefore the quality of the real-time view. You can try to adjust the antennas so the flat sides of the antenna point towards the Phantom 4 RTK. Yes, if the video transmission signal is lost, you can reconnect and continue the mapping mission. Yes, the Phantom 4 RTK and Pro batteries are cross compatible and have the same capacity, meaning flight time won't be effected. It takes roughly 60 minutes to fully charge a Phantom 4 RTK battery. Batteries should be stored in a dry, ventilated, cool environment, away from fire, high temperature and flammable materials.Do not put the battery in an environment that may cause the battery temperature to rise, such as in the sun, or under the direct sunlight inside your car.Long-term storage should ensure that the amount of electricity is more than 50% but not fully charged. The battery should be charged and discharged to maintain the battery activity every 3 month for long-term storage. This means the voltage of the battery cell is low and should be charged soon. Please be cautious when flying under this situation. The battery capacity (and therefore flight time) will sharply decrease in low temperatures (< -10℃/14℉). It is recommended to heat the batteries to 20℃/68℉ before flying to limit this effect. For flight safety, the battery cannot be charged when the temperature is below 5℃/41℉ or above 40℃/104℉. This is a normal phenomenon. When batteries have been stored for a long time with over 65% of the charge remaining, an automatic discharging procedure is activated to decrease battery level to 65%, during which the batteries will heat up. 1. Connect locally via OcuSync to your D-RTK 2 Mobile Station. (RTCM3.2) The Phantom 4 RTK can achieve 1 cm+1 ppm (horizontal), 1.5 cm + 1 ppm (vertical) accurate data. TimeSync continually aligns the flight controller, camera and RTK module, then adjusts the positioning data to the center of the CMOS and records the data in EXIF and XMP format. RTK and PPK are two different kinematics technologies that reference data in different ways. Although PPK generally has slightly higher positioning accuracy than RTK, both achieve centimeter-level precision. RTK is recommended for users flying in environments that allow for real-time connection via OcuSync or 4G and prefer convenience and efficiency. For users who have no demand on timeliness and/or need to operate in conditions without connectivity, PPK is a better option. EVENTLOG.bin is a binary format that stores exposure, time stamp and log file. Open the photo in text format and search "XMP" to find this information on each photo. Due to the new TimeSync system, each photo stores the position of the CMOS center in its metadata. For each photo, the compensation value between the RTK module's antenna phase center and the CMOS center in NED coordinate system is recorded in the timestamp. MRK file under a folder named “survey”. The Phantom 4 RTK firmware upgrade process is similar to that of the Phantom 4 Pro. Using the DJI Assistant 2 software, you can update the remote controller and aircraft firmware separately .
Currently the left/right TOF and infrared sensors are not active, so please fly with caution. Users can use the pre-installed GS RTK app for mapping or inspection missions. Additionally, users can install apps built on DJI's Mobile SDK. No.The RTH logics in both aircrafts are almost the same. Mapbox is used to provide map data to the GS RTK app. There is no limitation when using the GS RTK App. No. No. Currently the GS RTK app supports up to 99 boundary points through KML files. Currently the Phantom 4 RTK supports RTCM 3.0 data, RTCM 3.1 data, MSM4,MSM5, MSM6 and MSM7 data under RTCM3.2. The coordinates measured by the Phantom 4 RTK are absolute coordinates under WGS84. You can refer to the equation H=36*GSD to estimate an appropriate flight altitude. Please note that GSD ground sampling distance in this equation is measured by centimeters, while H (Height or flight altitude) is measured by meters. For example, GSD=2.74 cm, when altitude=100 m. Elevation and relative altitude (relative to your takeoff point) are stored in photos captured by the Phantom 4 RTK. Absolute altitude can be used for mapping, and relative altitude can be found in the XMP file. Oblique imagery can be captured while flying in the Photogrammetry mode on the GS RTK app. In the Photogrammetry mode, you can adjust gimbal angle from -90 °to -45° under Camera Settings for your flight plan.You can only set one gimbal angle value at a time, so for sites where you want to capture multiple angles you can plan the same mission and just adjust the camera angle. Yes, you can use third-party software to process Phantom 4 RTK image data and create models, however the accuracy will vary based on the photogrammetric algorithm used. Please refer to the third-party software provider for more information on expected accuracy. The orthoimages created with the images captured by the Phanton 4 RTK and select reconstruction software have shown an absolute accuracy of roughly 5 cm, while the accuracy required in 1:500 scale aerial triangulation is less than 30 cm. This means the Phantom 4 RTK's accuracy meets the requirements of 1:500 scale aerial maps. No, you cannot connect third-party base stations to the Phantom 4 RTK or the remote controller via a radio station. However, you can obtain data from a network RTK server via Ntrip protocol in 4G/Wi-Fi network environment. Satellite observation data can also be saved in the aircraft for users to conduct post processed kinematics (PPK) to complete their tasks.
