Abstract:
The basic principle and technology evolution of Two-Way Satellite Time and Frequency Transfer(TWSTFT) are introduced, the method and error sources of TWSTFT based on pseudo random noise code phase measurement are emphasized, and recent progress of a few important research points is discussed, such as TWSTFT based on dual pseudo random noise code, carrier phase TWSTFT technology and diurnal variation in TWSTFT. Aimed at the main problems that restrict the performance improvement of TWSTFT technology, some key points for the development of TWSTFT technology are proposed.
Key words:  TWSTFT  Dual pseudo random noise code  Carrier phase  Diurnal
