Key Points

The aim is to assess how differences between nominal and true reference station locations affect positioning errors in differential GPS systems.
Analyzed the impact of atmospheric delay differences between user and reference stations.
Explored how the nominal position resolution of reference stations affects positioning accuracy.
Evaluated a correction method for differential GPS to mitigate positioning errors.
Achieved up to 20mm reduction in positioning error due to nominal location resolution adjustments.
Confirmed significant error suppression during the relocation of reference stations.
