Geodion — Precision in Geodesy

About Geodion

Scientific depth. Practical delivery.

Independent geodetic expertise for organisations that need reliable positioning, defensible models, traceable reference systems and clear technical decisions.

Experience relevant to complex geodetic decisions

Dr Nadim Dayoub's professional background spans research institutes, offshore survey operations, geospatial engineering, national reference-system implementation, university teaching and independent consultancy.

Work has included coastal-altimetry algorithm development, calibration and validation of satellite data, Tier-3 offshore GNSS support, positioning quality control, national-to-global coordinate transformations, vertical-datum assessment, geoid modelling and specialist scientific software.

Geodion applies this experience selectively: clarifying the technical question, reviewing the evidence and delivering an answer that can be understood, checked and used.
