Abstract
Position calculating methods and devices are described. Satellite information may be calculated, which includes satellite position, satellite movement speed, and satellite movement direction of a positioning satellite. A pseudo distance between the positioning satellite and a user may be calculated based on a satellite signal received from the positioning satellite. The position of the user may be calculated using the satellite information and the pseudo distance in executing a convergence calculation with positioning information for a reference satellite, thereby eliminating a time error term from unknown quantities.
