Application of RTK-GNSS technology for field surveys based on cm-level high-precision positioning information

High-precision positioning using the Real Time Kinematic (RTK) Global NavigationSatellite System (GNSS) has attracted attention among field researchers who need accurate positional data for recording field sampling sites or correctly eoreferencing various maps and images. However, because of the cost involved in the purchase and running of RTK-GNSS receivers, it is imperative to choose the equipment with the most suitable positioning function. Positioning accuracy with and without RTK correction has been compared in this study during its use in field surveys. Furthermore, the benefits of RTK-GNSS location were discussed, along with applications to other research scenarios
