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