Abstract

Lunar phase radio ranging can be an addition to or even a replacement for the traditional LLR (Lunar Laser Ranging) observations. We present our preliminary data received as a result of the Chang'E-3 lander’s phase radio ranging observations processed and analysed. The observations were carried out using the Chinese radio telescopes “Kashi”, “Jiamusi” and Russian “Quasar” VLBI network. We propose several methods to take into account the atmospheric delay and to calculate the values of phase ambiguities. Our measurement post-processing show that the observation accuracy obtained correspond to the previouslsy stated ones. The RMS corrections to the selenocentric coordinates of the Chang'E-3 lander are included in this paper as well.
