A new gravimetric geoid model for Sudan using the KTH method

► We compute a new gravimetric geoid model over Sudan. ► We compile heterogeneous data to compute and validate the model. ► We use modified kernels to reduce truncation errors due to limitations. ► We validate the model against 19 GPS-levelling points. ► The model shows absolute accuracy of about 30 cm and relative accuracy 0.5 ppm.
