Cosmos 2559, the fifth GLONASS-K satellite launched, continues Russia's slow generational transition away from the Soviet-derived FDMA broadcasting method that made GLONASS receivers historically more complex and expensive to build than GPS equivalents. GLONASS-K's unpressurized bus design, borrowed from Western satellite manufacturing philosophy rather than the traditional heavier pressurized Russian approach, reflects a genuine technical convergence between Russian and international satellite engineering practice.
