Scientific paper

ASTROD-GW (ASTROD [Astrodynamical Space Test of Relativity using Optical Devices] optimized for Gravitation Wave detection)is an optimization of ASTROD to focus on the goal of detecting gravitation waves. The three spacecraft in the mission orbits are chosen to be near the Sun-Earth Lagrange points L3, L4 and L5. They form a nearly equilateral array and an interferometric array with the arm lengths of about 260 million kilometers. A set of 20-year optimized mission orbits of the ASTROD-GW spacecraft is worked out by us. With this, we perform the time delay interferometry simulation numerically using CGC2.7 ephemeris framework.
