Abstract: ASTROD is a relativity mission concept encompassing 
multi-purposes. One of its main purposes is to detect gravitational waves 
sensitive to low-frequency band similar to LISA, but shifted to lower 
frequencies. In this aspect, ASTROD would complement LISA in probing the 
Universe and study strong-field black hole physics. Since ASTROD will be 
after LISA, in the Cosmic Vision time-frame 2015-2025, a ten-fold 
improvement over LISA accelerometer noise goal would be possible, allowing 
us to test relativistic gravity to 1 ppb and improve the gravitational-wave 
sensitivity. In this paper, we address to this possible improvement, 
especially in the frequency range below 0.1 mHz. We look into possible 
thermal noise improvement, magnetic noise improvement, spurious discharging 
noise improvement and local gravitational noise improvement. We discuss 
various possibilities of lower-frequency gravitational-wave responses and 
their significance to potential astrophysical sources.
