SUBSTANCE: device has three independent pairs of identical lasers with different space between optical axis of each pair and one resonator which is shared by all lasers. Resonator of each laser has identical absorbing cells in order to stabilize beam which is generated in resonators. This results in possibility to achieve stable interference pattern. Since output frequency of resonator which is stabilized by absorbing cell depends on gravity potential which influence absorbing cell, frequency difference in each of resonators is unique for every pair. This results in possibility to use three independent pairs of lasers for three independent differences of gravitation potential. Known potential differences and distance between optical axes of laser, provide values of derivatives in position of resonator which is shared by all pairs.
