The high-accuracy positioning system will meet centimeter level industry application

and the market will be huge in the future. The system consists of satellite systems

reference stations

high-accuracy positioning platforms and mobile terminals. The transmission network between the reference station and the high-accuracy positioning platform is the basis of the system. Building a safe

smart

low-cost and easy to realize transmission network is the key to ensure high-accuracy positioning system. The paper introduces the architecture of the high-accuracy positioning system

and predicates the bandwidth requirements. Packet transport network +IP bearer network is proposed

to realize building transmission network of the high-accuracy positioning system.
