Utilization of Quasi-Zenith Satellite System for Navigation of a Robot Combine Harvester

The purpose of this study is to evaluate the performance a robot combine harvester by comparing Centimeter Level Augmentation Service (CLAS) and Multi-Global Navigation Satellite System (GNSS) Advanced Demonstration tool for Orbit Clock Analysis (MADOCA) from Quasi-Zenith (QZSS) using Real Time Kinematic (RTK) positioning technique as reference. first section evaluates availability precision under static conditions measuring activation time, reconnection obtaining Twice Distance Root Mean Square (2DRMS) 0.04 m 0.10 m, Circular Error Probability (CEP) 0.03 0.08 (RMSE) 0.57 0.54 CLAS MADOCA, respectively. second accuracy dynamic GNSS navigation-based running in an experimental field. results show that RMSE lateral deviation between 0.69 MADOCA 0.31 CLAS; which suggest augmentation system can be utilized if user considers these characteristics.
