摘要：

The proposed K(a) band link on the Cassini orbiter can be used for very accurate Doppler tracking. A two-way K(a) band coherent link, near opposition, or more complex schemes involving the X-band link also, can virtually eliminate the noise due to interplanetary plasma, giving an accuracy DELTAf/f better than, 10(-15) for time scales of (103 divided-by 10(4)) s. To achieve this accuracy, the other error sources, mainly the tropospheric delay and the clock stability, must be accurately controlled. This sensitivity will allow for the first time for a search for gravitational waves of reasonable amplitude.
