EnglishThe paper investigates different solutions for handling of ionospheric delays in high accuracy long baseline relative positioning by Carrier-based Differential GPS (CDGPS). Standard literature approaches are reviewed and the relevant limitations discussed. Hence, a completely ionospheric-free approach is proposed, in which the differential ionospheric delays are cancelled out by combination of dual frequency GPS measurements. The performance of this approach is quantified over real-world spaceborne GPS data made available by the Gravity Recovery And Climate Experiment (GRACE) mission and compared to the standard solutions
