That adds a lot of clarity, so maybe this story just doesn't add up. Also, I have to wonder if using Glonass as a backup to GPS might be sensible for western weaponry on the basis that Russia's military would not likely jam their own guidance systems. Same for using BeiDou on the likelihood that China's military would not likely jam it either.
