Abstract:
1. An apparatus for synchronization with a master-clock, the apparatus comprising: a memory having a curved space-time correction module stored therein wherein the memory includes the current position (r where G is the universal gravitational constant, M is the mass of the Earth where c is the speed of light in a vacuum, where R E is the Earth's equatorial radius, and where Λ(r T , r R ) is a function of the position associated with the master clock, r T , and the position of the apparatus, r R , and which is given by the equation: and θ T and θ T are defined by a=T, R; and a processor in communication with the memory, the processor adapted to receive a reference message having a time-stamp from the master clock, wherein the processor determines a correction to the time-stamp using the curved space-time correction, and wherein the correction accounts for curvature in space time.
