It is shown that there is a contribution to the precession of a gyroscope due to the quadrupole moment of the Earth. The magnitude of this additional precession is a maximum for a gyroscope in a satellite in equatorial orbit around the Earth at a moderate altitude, and exceeds the experimental error for observations which cover a span of about one year or greater.
