Cosmos 2596 is one of the last GLONASS-K1 satellites Russia built before fully transitioning to the heavier, more capable GLONASS-K2 generation. Over a decade after the design's 2011 debut, GLONASS-K's core innovation — CDMA broadcasting compatible with GPS, Galileo, and BeiDou receiver chips — remains its most consequential legacy, even as the newer K2 satellites now carry that same capability forward with substantially more broadcasting power.
