We propose to place such precise clocks in space and to use Doppler tracking method for detecting low-frequency gravitational wave below 1 Hz. Our idea is to locate three satellites at one A.U. distance (say at L1, L4 & L5 of the Sun-Earth orbit), and apply the Doppler tracking method by communicating ``the time" each other. Applying the current available technologies, we obtain the sensitivity for gravitational wave with three or four-order improvement (h_{n}\sim 10^{-17} or 10^{-18} level in 10^{-5} Hz -- 1 Hz) than that of Cassini satellite in 2001. This sensitivity enables us to observe black-hole mergers of their mass greater than 10^5 M_\odot in the cosmological scale. Based on the hierarchical growth model of black-holes in galaxies, we estimate the event rate of detection will be 20-50 a year.
