Abstract: According to an embodiment, an electronic device may comprise: memory storing instructions and at least one processor, comprising processing circuitry, individually and/or collectively. The instructions, when executed by at least one processor, cause the electronic device to: identify a position of the electronic device and at least one satellite from a GPS signal based on identifying a first event, identify whether a value based on a relative angle between a trajectory axis corresponding to the at least one satellite and the electronic device meets a first condition, identify whether a value based on a relative distance between the electronic device and the at least one satellite meets a second condition based on identifying that the value based on the relative angle does not meet the first condition, set a first power lower than a third power to a transmission power of a transmission signal corresponding to satellite communication based on identifying that the value based on the relative distance meets the second condition, and set a third power to a transmission power of a transmission signal corresponding to satellite communication based on identifying that the value based on the relative distance does not meet the second condition.
