GCP and PPK Utilization Plan to Deal with RTK Signal Interruption in RTK-UAV Photogrammetry
Drones, 2023 When surveying a large target area with a real-time kinematic unmanned aerial vehicle (RTK-UAV), the RTK signal tends to be disconnected when city canyons or macrocells are included. Thus, the accuracy is reduced due to the lack of RTK signal or the fact
