Dear everyone,

A colloquium talk will be held this Friday afternoon. Detailed information is as followings:



Speaker: Dr. Qinghui LIU

Affiliation: RISE Project Office, National Astronomical Observatory, Japan

Title: Studies on Doppler and differential VLBI techniques in Kaguya (SELENE) for lunar gravity field

Time: 2:00PM, Aug. 1st (Friday)

Location: middle conference room, 3rd floor

Outline:

Doppler technique (Sensitivity in line-of-sight), 35pages

Spin influence on Doppler measurement

Removing spin influence using LPF and detecting signal of lunar gravity on far side

Orbit determination for three satellites in SELENE

New global lunar gravity model, SGM90e

Phase characteristic of onboard antenna

Differential VLBI technique, 35pages

(Sensitivity in direction perpendicular to LOS)

SELENE VLBI observations and the system

Pico-second-accuracy differential phase delay (correlation + error analysis)

Orbit determination using Doppler+VLBI data.



Please tell each other to participate in.

Welcome to attend! : )
