This paper discusses the possibility of constructing an inertial system of coordinates, precise within 0.001 sec, with the aid of measures of mutual angular distances of quasars by the VLBI technique used in radio astronomy. Such a system depends on neither the rotation nor revolution of the earth around the sun - a fact which permits separation of the astronomical and geophysical aspects of the problem. The proposed system should permit resolution of some general astrometric problems, such as the precession and nutation of the earth, the motion of the terrestrial axis of rotation within the earth, or fluctuations in the angular velocity of terrestrial rotation.
