基础物理学和导航用日地拉格朗日参考
Sun-Earth Lagrange reference for fundamental physics and navigation
摘要：
介绍了利用日地系统的四个拉格朗日点进行空间基础物理实验的情况。L1、L2、L4和L5与地球一起刚性旋转，形成内太阳系尺度的自然参考系。本文讨论的思想考虑了在所引用的四个拉格朗日点上定位四个航天器并在它们之间交换电磁脉冲的可能性。包括地球上的站在内，脉冲的各种封闭路径都是可能的。将进行飞行时间测量。右手和左手电路之间的飞行时间差与太阳的角动量成正比，并且根据时钟的精度，对这种效应的检测将达到优于1%的精度。这四个点也可以作为太阳系尺度的相对论定位系统的“人造卫星”。其他令人感兴趣的可能性包括探测银河系的重力磁场，以及使用全球配置作为零面积萨尼亚克轮廓，探测引力波。还提到了更多的机会。
英文摘要：
The use of four Lagrange points of the Sun/Earth system for fundamental physics experiments in space is presented. L1, L2, L4 and L5 rotating rigidly together with the Earth form a natural reference frame at the scale of the inner solar system. The idea which is discussed in the paper considers the possibility of locating four spacecraft in the four cited Lagrange points and exchanging electromagnetic pulses among them. Including stations on earth, various closed paths for the pulses are possible. Time of flight measurements would be performed. The time of flight difference between right- and left-handed circuits is proportional to the angular momentum of the Sun and the detection of the effect would reach accuracies better than 1% depending on the accuracy of the clock. The four points could also be used as "artificial pulsars" for a relativistic positioning system at the scale of the solar system. Additional interesting possibilities include detection of a galactic gravito-magnetic field and also, using a global configuration as a zero area Sagnac contour, detection of gravitational waves. More opportunities are also mentioned.
