There is proposed a new experiment with two atomic clocks, whose analysis disproves Einstein's postulate of light speed invariance. Two spaceships moving at the same speed V in the same interplanetary orbit send each other optical or radio signals, similar to GPS, measuring the time and the speed of the signals. The signals move in opposite directions through the distance between giving a shift of time intervals that can be explained only by the fact that the signals travel at different speeds, c-v and c+v. The result of this experiment can not be refuted by any relativistic arguments.
