Differential GPS Corrections for the Error in the Nominal Location of Reference Station

Puntos clave

• 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.
