GLONASS
Center of Mass Information:
For the GLONASS satellites equipped with the 120 cm x 120 cm array (those launched before 1996), limited CoM information is available.
GLONASS-84 uses a different RRA than the other GLONASS satellites. GLONASS-84 has 132 corner cubes (132 cube arrangement). The corner cubes are mounted within a circular area having a 330-mm radius. Two (GLONASS-86, -87) of the three GLONASS satellites launched on December 1, 2001 (GLONASS-86, -87, -88) have the same array as GLONASS-84, but one (GLONASS-88) has a different array of only 124 cubes (124 cube arrangement).
Analysis has been done on the GLONASS retroreflector array position relative to CoM for the newer satellites GLONASS-87, -89, -95, -99, -100, -102, -109, and -115. The CoM correction values for the GLONASS-K satellites (GLONASS-125) are also available.
