vlbi observations with the Kunming 40-meter radio telescope

引用

Research in Astronomy and Astrophysics 2010年第8期10卷 805-814页

作者： Long-Fei Hao Min Wang Jun Yang National Astronomical Observatories / Yunnan Observatory Chinese Academy of Sciences Kunming 650011 China Joint Institute for vlbi in Europe Postbus 2 7990 AA Dwingeloo The Netherlands

The Kunming 40-meter radio telescope is situated in the yard of the Yunnan Astronomical Observatory （Longitude： 102.8° East, Latitude： 25.0° North） and saw its first light in 2006 May. The Kunming station successfully joined the vlbi tracking of China＇s first lunar probe ＂Chang＇E-1＂ together with the other Chinese telescopes： the Beijing Miyun 50-meter radio telescope, Urumqi Nanshan 25-meter radio telescope, and Shanghai Sheshan 25-meter radio telescope, and received the downlinked scientific data together with the Miyun station from October of 2007 to March of 2009. We give an introduction to the new Chinese vlbi facility and investigate its potential applications. Due to its location, the Kunming station can significantly improve the u - v coverage of the European vlbi Network （EVN）, in particular, in long baseline observations. We also report the results of the first EVN fringe-test experiment of N09SX1 with the Kunming station. The first fringes in the European telescopes were successfully detected at 2.3 GHz with the ftp-transferred data on 2009 June 17. From scheduling the observations to performing the post correlations, the Kunming station shows its good compatibility to work with the EVN. The imaging result of the extended source 1156＋295 further demonstrates that the Kunming station greatly enhances the EVN performance.

Measurements of the vlbi experiments during the first campaign of the Asian-Pacific space geodynamics (APSG) program

During the first campaign of the Asian-Pacific space geodynamics (APSG) program in October 1997, two VLBl experiments were successfully organized and coordinated by the Astrometry and Geodesy VLBl Group of Shanghai Astronomical Observatory, the Chinese Academy of Sciences, cooperated with geodetic VLBl group, GSFC, NASA, USA. Six VLBl stations participated in the experiments, including Seshan and Urumqi station of China, gilcreek station in Alaska and Kokee station in Hawaii of USA, Kashima station of Japan and Hobart station at Tasmania of Australia. Baseline lengths are from 1 900 to 11 000 km and the mean relative uncertainty of the baseline length measurements is 1.0 x 10-9. In addition, the rates of the baseline lengths among the six stations and their three-dimensional velocities are solved out via global analysis of the two APSG sessions and the historical observations of the six stations as well as other VLBl observations from the global observation network. These results are appreciable to the studies of the modern crustal movement in the Asian-Pacific region. Especially,an 8 mm/a eastward motion and a 14 mm/a north by northeast motion are detected respectively for Seshan and Urumqi stations relative to the stable part of the Eurasian plate. The motions directly illustrate the effect of the northward movement of Indian plate on the modern crustal motions of the northwestern and the eastern part of China, which is of important significance to the study of the modern crustal motion of China.

The analysis of GPS seasonal systematic error based on co-location sites

第四届中国卫星导航学术年会

作者： Tian Liang Sun FuPing Xi'An surveying and mapping station Information Engineering University

Make comparison between GPS、SLR and vlbi’s site coordinate seasonal non-linear variations with the collocation site’s coordinate vertical residuals. There are some comparability with those seasonal movements calculated by three space technologies. But the amplitude of vibration is different. The amplitude of vibration calculated by SLR is nearly the same with vlbi, different with GPS. The maximum difference is about 7 mm. So we conclude that there are some relativity between the errors and GPS seasonal systematic error.
