Abstract
The TWSTFT carrier phase technique permits to improve the short term stability of the two-way links. The basic idea of this method is to calculate the offset between the frequencies of the two remote clocks in comparison. The frequency of the local oscillator on-board and Doppler coefficients are also determined. By applying the carrier phase method using the two OP ground stations in a common clock mode, a frequency stability of 1×10−12 is reached at 1 s while with the OP satellite simulator, a value of 4×10−13 is achieved.
