There are many areas where it is very difficult to carry out a topographic survey of the area. This applies not only to ground-based methods of obtaining data (using a GNSS receiver, total station, etc.), even when surveying using a drone, it is necessary to fix it on the ground and obtain the coordinates of markers placed according to a certain pattern.
Often, it is almost impossible to get to the place where it is necessary to place an identification mark. Or the identification was fixed on the ground, but when processing the data in the office, they noticed that it was displaced or disappeared. Everyone who works in this field understands that these are additional costs for reshoots.
When using Phantom 4 RTK, these questions do not arise, but as a rule, others arise, which will be described in this case, which DroneUA completed together with partners LLC Company "Topogeo". described in the article.
Data processing in PPK
To ensure that the Phantom 4 RTK drone receives corrections, it must be connected to a network of base stations
