利用光学装置进行天体动力学空间相对论测试（ASTROD）是一种由3个航天器组成的任务概念，一个在L1/L2点附近，一个在太阳内轨道，一个在太阳外轨道，利用激光进行相干测距，以测试相对论引力，测量太阳系和探测引力波。ASTROD I搭载一艘航天器与地面站进行光学测距，这是ASTROD任务的第一步。本文介绍了ASTROD 1的载荷和加速度计要求，讨论了ASTROD和ASTROD 1的引力波灵敏度，并将其与LISA和航天器无线多普勒跟踪进行了比较。
Astrodynamical 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 1, and compare them with LISA and radio-wave Doppler tracking of spacecraft.
