Drone PPK  GPS PPK Solution for DJI PHANTOM 4 Pro or DJI Mavic 2 Pro Drone Refit Pack  Drone PPK Mapping 

Why load PPK system for your DJI Drone?

When you fly a non-RTK drone or non-PPK with an onboard GPS receiver or a receiver along with the camera, camera positions are trilaterated from satellites so their positions are identified by several distance measurements. Normally, you can expect an inaccuracy of up to several meters, especially in Z directions, depending on the equipment quality and the satellite geometry.

While PPK is a high accuracy GPS like RTK that does not need a radio link between the aerial mapping drone and the base and does the corrections post collection. PPK systems offers many advantages to drones 1. it eliminates the need for ground control points. Greatly reducing the field work required for each mission. 2. It cleans up the data reducing many of the point errors seen on common areas in point clouds
