摘要:

2012年2月成功发射了LARES(激光相对性卫星)卫星。LARES空间实验的基础是激光测距卫星LARES、LAGEOS(激光地球动力学卫星)和LAGEOS 2的轨道测定,以及GRACE(重力恢复和气候实验)任务对地球重力场的测定。它将测试一些基本的物理学预测,并提供爱因斯坦的广义相对论预测的框架拖曳效应的精确测量。通过对LARES实验的100次蒙特卡罗模拟,并根据GRACE最新的重力场测量结果对LARES、LAGEOS和LAGEOS 2的轨道进行模拟,发现标架拖曳测量的系统误差约为广义相对论效应的1.4%,证实了以前的误差分析。

英文摘要:

The LARES (LAser RElativity Satellite) satellite was successfully launched in February 2012. The LARES space experiment is based on the orbital determinations of the laser ranged satellites LARES, LAGEOS (LAser GEOdynamics Satellite) and LAGEOS 2 together with the determination of the Earth's gravity field by the GRACE (Gravity Recovery And Climate Experiment) mission. It will test some fundamental physics predictions and provide accurate measurements of the framedragging effect predicted by Einstein's theory of General Relativity. By one hundred Monte Carlo simulations of the LARES experiment, with simulations of the orbits of LARES, LAGEOS and LAGEOS 2 according to the latest GRACE gravity field determinations, we found that the systematic errors in the measurement of framedragging amount to about 1.4% of the general relativistic effect, confirming previous error analyses.
