Table 2:

Ground laser (532 nm) ranging stations used as primary station; (Sun et al. 2013)⁽¹⁾, (Abshire et al. 2007)⁽²⁾, (Samain et al. 2015)⁽³⁾, (Schreiber and Kodet 2017)⁽⁴⁾. These SLR stations use a H-maser clock and picosecond resolution and precision event timer. For the GGAO site, we separated the different experiments that were conducted since 2005 on MLA (MESSENGER), MOLA (MGS) and LRO equipped with a 1-way uplink.
