FIELD: radio engineering, communication.
SUBSTANCE: system for automatic adjustment of frequency of scattered lasers with a continuous radiation mode includes multiple coupled automatic frequency adjustment circuits, each including series-connected photomixer, discriminator, integrator and direct current amplifier connected to a piezoelectric corrector of the radiation frequency of the corresponding continuous wave laser, wherein one automatic frequency adjustment system from two continuous wave lasers is mounted on an artificial earth satellite which is fixed relative the earth, and the other two are mounted on the earth's surface.
EFFECT: enabling measurement of blue shift of monochromatic radiation of a powerful continuous wave laser which is aimed at the earth's surface from an artificial earth satellite which is fixed over a given point on the earth's surface due to the effect of the earth's gravitational field.
