The Principle and Application of Maser Navigation [PDF]
The traditional celestial navigation system (CNS) is used the moon, stars, and planets as celestial guides. Then the star tracker (i.e. track one star or planet or angle between it) and star sensor (i.e. sense many star simultaneous) be used to determine the attitude of the spacecraft. Pulsar navigation also be introduced to CNS.

Beidou Time Synchronization Receiver for Smart Grid
AbstractA time synchronization system based on the Chinese GPS system i.e. Beidou or Compass for smart grid applications is illustrated. A time synchroni-zation Beidou receiver with self-designed radio frequency IC (RFIC) is presented. The receiver provides precise one pulse per second (1PPS) timing service for the smart grid.
