Initial results confirmed the expected geodetic effect to an accuracy of about 1%. The expected frame-dragging effect was similar in magnitude to the current noise level (the noise being dominated by initially unmodeled effects due to nonuniform coatings on the gyroscopes). Work continued to model and account for these sources of error, thus permitting extraction of the frame-dragging signal. By <time datetime="2008-08">August 2008</time>, the frame-dragging effect had been confirmed to within 15% of the expected result, and the <time datetime="2008-12">December 2008</time> NASA report indicated that the geodetic effect was confirmed to better than 0.5%.
