Show affiliationsAstrodynamical space test of relativity using optical devices (ASTROD) is a mission concept with three spacecraft—one near the L1/L2 point, one with an inner solar orbit and one with an outer solar orbit, ranging coherently with one another using lasers to test relativistic gravity, measure the solar system and detect gravitational waves. ASTROD I with one spacecraft ranging optically with ground stations is the first step towards the ASTROD mission. In this paper, we present the ASTROD I payload and accelerometer requirements, discuss the gravitational-wave sensitivities for ASTROD and ASTROD I, and compare them with LISA and radio-wave Doppler tracking of spacecraft.
