The Beidou satellite navigation system is composed of three parts: the space segment, ground segment and user segment. It can provide high-precision, highly reliable positioning, navigation and timing services for all types of users around the world and around the clock.
It has short message communication capabilities and has initially possessed regional navigation, positioning and timing capabilities. The positioning accuracy is 10 meters, the speed measurement accuracy is 0.2 meters per second, and the timing accuracy is 10 nanoseconds.
