LARES and LARES-2 will achieve important measurements in gravitational physics, General Relativity, space geodesy and geodynamics, in particular, together with the LAGEOS-1 and LAGEOS-2 satellites and with the GRACE models, it will provide a very accurate determination of the Earth gravitomagnetic field and of the Lense-Thirring effect.

The International Space Time Analysis Research Center provides the International Laser Ranging Service-ILRS, the orbital predictions for LARES for pointing of the tracking telescopes toward the target. The paper describes the technical aspects of generating the orbital predictions.

激光相对论卫星 (LARES)是一颗小型低成本 探测卫星，于法属圭亚那当地时间2012年2月13日7:00搭载在欧洲织女星火箭上发射升空。 发射激光相对论卫星旨在验证爱因斯坦广义相对论，耗资仅1000万美元，其探测精度将比此前美国宇航局进行的该项研究高出几乎100倍。 激光相对论卫星由意大利领衔研制，项目的负责人是意大利萨兰托大的伊戈纳兹尔·塞佛利尼。 发射成功后，这颗卫星开始在轨工作，它将在2012年后的数年内连续发回有关 惯性系拖曳效应 的测量数据。 …

In this study, the contributions of LARES and LARES-2 SLR data to multi-satellite SLR analyses in combination with LAGEOS-1/2 are validated. Since, compared to LAGEOS-1/2, LARES orbits the Earth on a lower altitude (1400 km) it is more sensi-tive to the time-variable Earth’s gravity field and therefore enables to co-estimate

Main mission (in combination with LAGEOS-1, LAGEOS-2 and LARES): to confirm the principle of General Relativity that rotating masses drag space-time around themselves as they rotate (“Lense-Thirring effect”). Substatial contribution to Solid Earth (space geodesy). Data freely available from the International Laser Ranging Service (ILRS).

2015年8月6日 · Abstract: LARES is an Italian Space Agency mission designed to test General Relativity in the weak field of Earth. In particular, the satellite will be able to measure frame-dragging with an accuracy of about 1%.

After a few years of the LARES satellite (to be launched at the end of 2011) laser-ranging data will be available, together with future improved Earth’s gravity models, the accuracy of the frame-dragging measurement should approach 1 %.

2022年7月13日 · Thanks to its characteristics, LARES-2, consisting of a high-density nickel sphere (424 mm in diameter and 300 kg in mass) equipped with 303 CCR (Cube Corner Retroreflectors), will represent a perfect reflecting target for the laser beams sent by the International Laser Ranging Service (ILRS) stations, which will hit the satellite during its ...

2022年8月1日 · 2022年7月24日，长春KHz高重复频率常规卫星激光测距系统首次成功观测到最新加入ILRS国际联测的lares2卫星，有效数据点20770点、内附精度10.6mm、观测弧段15min。 图1是长春站观测lares2卫星的观测界面截图。 lares2卫星是lares组的第二颗卫星，与其前身 lageos和lares 任务相比，lares2任务的主要科学目的是大大提高卫星环绕地球轨道的测量精度，以及测量地球的重力磁场。
