Time Offset Comparison per Code Measurements in GPS Time Transfer

This paper shows the comparison result of time offsets using P1, P2 and P3 in GPS time transfer. We modified r2cggtts program in order to calculate time offsets for two single frequencies, P1 and P2. The result shows that time offsets using P1 and P2 are of wide dristribution comparing to time offsets using P3. As a further study, the error factors for wide distribution of P1 and P2 should be studied.
