Abstract:

TWSTFT theory based on the code pseudo-ranging and the error in which is analyzed. For the code rate limited, the precision of the system is difficult to be promoted. So, the TWSTFT based on the carrier-phase measuring is presented, which can enhance the precision more for the high frequency and short wave of the carrier. And the error source in the carrier-phase measuring TWSTFT is analyzed in the paper, result shows that the major source is the errors caused by ionosphere, transponder, and the relative moving between the earth station and satellite.

Key words: TWSTFT, carrier-phase, error analysis.
