RELIABILITY CHECK OF POSITIONING ACCURACY UNDER THE CANOPY OF BROADLEAF DECIDUOUS FOREST (BROADLEAF OAK-QUERCUS CONFERTA) USING NETWORK-BASED RTK TECHNIQUES

Chrysanthi Argiropoulou, Kosmas Aristotelis Doucas

Abstract :

The creation of Permanent Reference Stations and the implementation of network positioning techniques can significantly improve the accuracy in positioning in forest and forest area.The HEPOS System (HEllenicPOsitioning System)is the first Network of Permanent GPS Reference Stations that developed in Greece. The system provides high accuracy satellite-based positioning services. The aim of the paper is to investigate the positioning accuracyunder the canopy of oadleaf deciduous forest(Quercusconferta)in accordance with different growth seasons(with and without leaves).So two measurement testing courses were established: during the summerwhen the tress had leaves and during the springwhen the trees had no leaves.TheGPS receiver Leica GS09 GNSS and the Total Station LEICA TRC 407 (for true values) are used.Real Time Kinematic positioning (RTK)are applied by using theHEPOS. Four RTK GPS techniques: the VRS, the MAC, the Single-Base and the Network-based DGPS technique were implemented.
