Abstract

In this paper, we report on the mission study and laboratory development for ASTROD. ASTROD mission concept is to use drag- free spacecraft in solar orbits together with a constellation of Earth orbiting satellites to provide high-precision measurement of relativistic effects, better determination of the orbits of major asteroids, improvement in the measurement of G, measurement of solar angular momentum via Lense-Thirring effect and the detection of low-frequency gravitational waves and solar oscillations in a single mission. We present our progress in the mission study on the various aspects for measuring these quantities. As to the laboratory development, after reviewing briefly our progress in log fiber-linked heterodyne interferometer and tunable fiber directional coupler, we present our progress in weak light optical phase locking, fiber delay-line and laser and time metrology.
