Abstract
A moveable object determines a preliminary position for the moveable object using received satellite navigation signals and satellite orbit correction information and satellite clock correction information. A position correction is determined by identifying which cell, of a predefined set of geographical cells, corresponds to the determined preliminary position, and obtaining from a database, pre-computed tectonic terrestrial plate position information for the identified cell. Based on the information for the identified cell, a tectonic terrestrial plate, corresponding to the determined preliminary position of the moveable object is identified. Based on the identified tectonic terrestrial plate, a position correction is determined, the position correction corresponding to the identified tectonic terrestrial plate and a reference epoch, and a corrected position of the moveable object is generated in accordance with the determined preliminary position of the moveable object and the determined position correction.
