The paper considers a <strong>\u201c<\/strong>drag-free<strong>\u201d<\/strong> satellite measurement system for compensation of active accelerations of non-gravitational nature.

An analysis of basic schemes of single-frequency interferometers is given. A layout of a <strong>\u201c<\/strong>drag-free<strong>\u201d<\/strong> satellite measurement system is developed.
