Despite the other guy’s snarky comment about system system, he’s right that they are being added to the current system. They will replace aging satellites and join the current constellation of 31 operational satellites. You’re also right that there is a minimum number of satellites required for high availability globally. The geometry of the MEO constellation creates certain thresholds for different levels of availability. As we add capabilities to new satellites, it takes time to replace older ones and proliferate the new capabilities across the constellation for global availability.
