摘要
天琴计划是一项面向 Hz 1 Hz 频率窗口的未来空间引力波观测台。该频段预期包含大量引力波源，包括大质量黑洞双星并合、极端/中等质量比系统的旋近、恒星级黑洞双星、银河系致密双星等。天琴计划将由三颗轨道半径约 km 的近地轨道卫星组成。卫星将形成平面近乎垂直于黄道面的正三角形星座。天琴计划遵循「0123」技术路线图稳步推进。在「0」阶段，天琴激光测距站已建成，并成功对月球上的五个反射镜进行了测距。在「1」阶段， TianQin-1 卫星已测试并验证了无拖曳控制技术。在「2」阶段，将使用 TianQin-2 卫星对进行星际激光干涉测量技术的测试。TianQin-2 任务已正式获批，卫星将于 2026 年左右发射。在「3」阶段，即 TianQin-3 任务，三颗相同卫星将于 2035 年左右发射，以组成空间引力波探测器天琴，并开始在空间进行引力波探测。
