Cosmos 2485, launched in 2013, is a GLONASS-M satellite maintaining the fully restored constellation's global coverage. By this point GLONASS had transitioned from crisis-driven rebuilding into steady operational maintenance — routine replacement launches keeping the 24-satellite constellation at full strength as individual satellites aged out, the same unglamorous but essential cycle every mature satellite navigation system depends on. GLONASS by 2013 had settled into steady operational maintenance rather than crisis-driven rebuilding, with satellites like this one representing the unglamorous but essential routine replacement cycle every mature navigation constellation depends on to avoid ever repeating a 1990s-style collapse.
