Speaking to Sky News about the security implications of the launch, Alexandra Stickings, space policy and security research analyst for think tank RUSI, said: "Global navigation satellite systems have become incredibly important for the military. "What these systems do is provide very accurate navigation and timing systems. These are used for everything from maritime navigation to precision weaponry. It's what make smart bombs smart, essentially. "The more that China is able to access these signals and the more accurate these signals become the more they can integrate that into their military, and then they could potentially start to rival the US in terms of precision military operations."
