Abstract : An experiment is proposed for an accurate and reliable measurement of the periodic relativistic doppler shift with a high-eccentricity, low-perigee-height orbit. Using a quartz crystal oscillator and existing proven hardware, the experiment would be both reliable and inexpensive with very little development required. An analysis is made of the errors in a previous similar experiment that was completed with the GEOS-I satellite. From the demonstrated capability in the GEOS experiment, it is concluded that a relative accuracy of better than 1% is attainable with an orbit eccentricity greater than 0.5. With an eccentricity as high as 0.9, the relative error would be of the order of 0.1%. (Author)
