The difference in travel time of corotating and counterrotating light waves in the field of a central massive and spinning body is studied. The corrections to the special relativistic formula are worked out in a Kerr field. An estimation of numeric values for the Earth and satellites in orbit around it show that a direct measurement is on the order of concrete possibilities.
