What is a RTK drone?

Real Time Kinematic (RTK) is a GPS correction technology technique that provides real-time corrections to location data as the drone is surveying and capturing images from a site. Drone RTK processing records GPS information and geotags the images taken as they’re captured during the flight.

How does DJI RTK work?

The DJI Phantom 4 RTK captures original satellite observation data as well as the ephemeris data and stores it in a PPKRAW. bin file in RTCM 3.2. format. Additionally, the Phantom 4 RTK converts the satellite data on the fly to the RINEX format (Receiver Independent Exchange Format) and writes the data into a RINEX.

Does DJI use RTK?

DJI has rethought its drone technology from the ground-up, revolutionizing its systems to achieve a new standard for drone accuracy – offering Phantom 4 RTK customers centimeter-accurate data while requiring fewer ground control points.

Can you add RTK to drone?

Adding RTK to an existing drone is an increasingly popular choice. The advantages of upgrading a drone to RTK include: Less expensive than a new drone. Drones are cheaper than ever – but professional UAVs are a significant investment for most businesses.

Is Phantom 4 RTK accurate?

1/10ft accuracy, every time you survey Walking a site, shooting points, establishing ground control—these things took days, sometimes weeks depending on the acreage. The Phantom 4 RTK has dismantled that delicate balance between quality and pace to reduce survey time to a matter of hours, without forfeiting quality.

Is RTK free?

In a nutshell, RTK is 1-2cm real-time positioning. Many of them make the RTK base data available to the public for free or for a nominal cost. If you work in an area that offers one, all you need is internet access in the field and a RTK-capable GPS L1/L2 receiver.

What is the difference between RTK and PPP?

PPP uses a single GNSS receiver, unlike standard RTK methods, which use a temporarily fixed base receiver in the field as well as a relatively nearby mobile receiver. PPP methods overlap somewhat with DGNSS positioning methods, which use permanent reference stations to quantify systemic errors.

What is RTK module DJI?

D-RTK is a high precision navigation and positioning system specially designed for DJI A3 series flight controllers. This enhanced accuracy over typical barometer, compass and GPS systems makes D-RTK essential for commercial, industrial and scientific applications where accuracy is imperative.
