摘要:

介绍了LARASE研究计划在模型改进和相对论测量方面的最新成果。特别是,关于影响LAGEOS和LARES卫星轨道的非重力扰动的新模型的发展的结果进行了描述和讨论。这些是微妙而复杂的影响,需要深入了解卫星的结构及其物理特性,才能正确地加以解释。在引力测量领域,我们介绍了一种新的相对论性Lense-Thirring进动的精确测量方法。文中还讨论了与地球引力场知识有关的误差在这类测量中的作用。最后,总结了近几年来利用激光跟踪被动卫星在相对论测量和约束方面取得的主要结果。突出了卫星激光测距技术在这些活动中的关键作用,以及它在空间大地测量和基本物理测量之间产生的能量。

英文摘要:

Recent results of the LARASE research program in terms of models improvements and relativistic measurements are presented. In particular, the results regarding the development of new models for the non-gravitational perturbations that affect the orbit of the LAGEOS and LARES satellites are described and discussed. These are subtle and complex effects that need a deep knowledge of the structure of the satellite and of its physical characteristics in order to be correctly accounted for. In the field of gravitational measurements, we introduce a new and precise measurement of the relativistic Lense-Thirring precession. The role of the errors related to the knowledge of the gravitational field of the Earth in this kind of measurements is also discussed. Finally, the main results in relativistic measurements and constraints obtained during the last few years by means of the laser tracking of passive satellites are summarized. The key role of the Satellite Laser Ranging technique in these activities is highlighted, together with the sinergy it produces between space geodesy and fundamental physics measurements.
