抄録（英）
Same beam VLBI (very long baseline interferometry) observations of the two sub-satellites of SELENE (KAGUYA) are demonstrated for purpose of the precise gravimetry of the Moon. The same beam VLBI contributes a great deal to cancel out the tropospheric and ionospheric delays and to determine the absolute value of the cycle ambiguity by using the multi frequency VLBI method. As a result, the differential phase delay of the X-band signal is estimated within an error of below one pico-second. This accuracy is more than one order of magnitude better than former VLBI results, revealing the possibility of precise gravimetry.
