Effect of the Earth's Revolution Around the Sun on the Proposed Gyroscope Test of the Lense-Thirring Effect

We analyze the proposed Stanford experiment (precession of the spin of a gyroscope in an Earth satellite) to test the Lense-Thirring effect. We show that the sun also makes a contribution to the precession which must be included, particularly if one wishes to distinguish between the Einstein and Brans-Dicke theories.
