第二代天体测量卫星及后依巴谷地面天体测量的进展

简述了后依巴谷的天体测量工作。首先给出了第二个天体测量卫星Gaia的最新进展、最近提出的JAMSE和OBSS计划的简介,以及包含天体测量内容的SIM PlanetQuest计划的情况; 叙述了多波段天体参考架的建立和维持,特别是依巴谷星表向暗星方向的扩充和数字巡天,以及其他地面观测计划,如双星和聚星、太阳系天体的观测等;介绍了天体测量与天体物理结合的几个研究课题的进展;最后对我国自然科学基金会“十一五”天体测量优先发展的方向与内容提出建议。

Second-Generation Astrometric Satellites and Post-Hipparcos Advances in Ground-Based Astrometry

Post-Hipparcos advances in both of space and ground-based astrometry is briefly described. First, the current progress of Gaia project is given; the programs of JAMSE and OBSS are introduced as well as the status of SIM Planet Quest project containing the astrometric content is reviewed. The establishment and maintenance of multi-wavelength reference frame are indicated, especially the extension of Hipparcos catalog down to faint stars, projects of digital sky survey as well as other plans of ground based observations, such as observing binary and multiple stars, solar celestial bodies are described in the third part of this paper. Fourth section gives the progress of several research subjects combining astrometry and astrophysics such as WOCS. SDSS. QUEST RR Lyrae survey and so on. Finally, our preliminary suggestion "the research on astrometric parameters and its application on the field of Galactic astronomy in large scale". which is as an advanced research subject supporting by the National Natural Science Foundation. is submitted during the eleven-five year plan.
