Cosmos 2500, launched in 2014, is a GLONASS-M satellite continuing routine constellation replenishment. Each satellite added extends the operational margin that keeps GLONASS providing continuous global coverage, insurance against the kind of rapid, uncontrolled decay that nearly destroyed the entire system in the 1990s when replacement launches simply stopped happening for years at a time. GLONASS's full recovery to global coverage by 2011 remains one of the more remarkable turnarounds in space infrastructure history — a system that had shrunk to six functioning satellites a decade earlier rebuilt entirely through sustained, deliberate national investment.
