HALCA phase transfer and statistical property of atmospheric phase fluctuations Original Research Article

The space orbiting radio telescope, HALCA, was placed into highly elliptical earth orbit on February 12, 1997. A master oscillator on board is phase locked to a reference signal generated by a hydrogen maser frequency standard in a ground tracking station. The frequency and the phase of the satellite oscillator are monitored in the ground tracking station. This paper provides a brief summary of the phase transfer link and gives the stability of the phase transfer link before and after the launch. Also this paper gives the discussions on the atmospheric phase fluctuations and the statistical property.
