Presented by Dr. Guangli WANG on 14 Mar 2016 from 17:00 to 18:00
Type: Poster Presentation
Track: 6: VLBI Observations of Space Vehicles
Board #: S6P1
VLBI technique was used in China’s Lunar Exploration Project Since the Chang’E-1 launched in the year of 2007, after then VLBI was played an important role in the series of Chang’E missions, CE-2, CE-3 and CE-5T1, and will be continued in the future space mission. The observation network consists of Shanghai 25m&65m, Beijing 50m, Kunming 40m and Urumqi 25m radio telescopes. Up to now it still works in the traditional astronomy-compatible S/X station systems , both quasar and S/C are observed in the same Frequency setup. In CE-1 & CE-2 the quasar and S/C switching rules are 15min quasar and 45min S/C, in CE-3 and thereafter are <5min switching.
