What is the most accurate GPS system?

Today, the US military’s GPS is still more accurate than what most of us can access. It’s good to the centimetre level, because it uses two frequencies to ping between satellites and receivers, one of which is encrypted.

What kind of data does a GPS use?

GPS operations depend on a very accurate time reference, which is provided by atomic clocks on board the satellites. Each GPS satellite transmits data that indicates its location and the current time. All GPS satellites synchronize operations so that these repeating signals are transmitted at the same instant.
