CONCLUSION. This study provides the first continent-wide position/velocity solution for Africa, expressed in ITRF2008, and is therefore a first contribution to the upcoming African Reference Frame (AFREF). Except for a few regions, the Afri-can continent remains largely under-sampled by continuous space geodetic data. Efforts are in order to augment the geo-detic infrastructure and openly share existing data sets so that the objectives of AFREF can be fully reached. In ad-dition to the geophysical implications of this work, we argue that using a static frame for territories lo-cated on stable Nubia is acceptable because of its low level of internal deformation. However, we also argue that deforming territories in northern and eastern Africa...
