GRU–Transformer Hybrid Model for GNSS/INS Integration in Orchard Environments

GRU–Transformer Hybrid Model for GNSS/INS Integration in Orchard Environments

Precision positioning in orchards relies on Global Navigation Satellite System and Inertial Navigation System (GNSS/INS) integration. However, dense foliage often causes GNSS blockages, degrading accuracy and robustness. This paper proposes an optimized GNSS/INS integrated navigation method based on...
