T‐SPP: Improving GNSS Single‐Point Positioning Performance Using Transformer‐Based Correction
International Journal of Intelligent Systems, Volume 2024, Issue 1, 2024.GNSS (global navigation satellite systems) technology enables high‐precision single‐point positioning (SPP) in open environments. However, the accuracy of GNSS positioning is significantly compromised in complex urban canyons due to signal obstructions and non‐line‐of‐sight propagation errors.
