The method performed by an electronic device, comprises receiving a distance (r) to a satellite that receives polarized photon from a sender and transmits the polarized photon to a receiver, receiving an angular momentum per unit mass of the satellite (lobs), and calculating a rotation amount of the polarized photon, which is induced by a warp of space due to gravity by using the distance to the satellite and the angular momentum per unit mass of the satellite (lobs). The rotation 2Θ of the polarized photon is calculated by the following equation, wherein ‘rs’ is the Schwarzschild radius of the Earth.
