VLBI2010技术是国际VLBI大地测量与天体测量服务组织（IVS）正在实施的下一VLBI观测系统，该系统充分考虑了空间大地测量学和天体测量学的潜在需求，利用宽带延迟技术和可快速转动的小到12米的无人值守天线，可在全球范围内达到1毫米的观测精度并提供近实时的连续EOP和测站位置时间序列，并实现对导航卫星的跟踪测量。本项目针对我国自主的EOP监测网络及北斗卫星导航系统（COMPASS）的论证与建设,研究利用VLBI2010技术解算EOP参数及改进COMPASS卫星轨道两个关键技术问题。主要研究相关的数据分析理论、模型及解算方法，并对相应观测网络的布网方案、观测计划及观测能力进行论证和评估。研究成果将极大的促进我国EOP监测网络的建设和COMPASS卫星导航系统的维护与改进。

VLBI2010 is a next-generation VLBI system implementing by international VLBI service for Geodesy and Astrometry (IVS), latent demands of Geodesy and Astrometry are given full consideration by new VLBI2010 system, and one millimeter position accuracy on global scales and near real-time to providing continuous measurements for time series of station positions and Earth Orientation parameters (EOP) can be attained based on the use of smaller (12 meters) fast-slewing automated antennas,in the meantime, GNSS satellites can be observed by VLBI2010 as well. Aiming at the demonstration and establishment of China EOP autonomic service and precise orbit determination of China COMPASS satellite navigation system, two critical technical problems about solutions of EOP and improvements of COMPASS satellite orbits used with VLBI2010 will be studied in this project.The research content mainly includes the relevant data analysis theory, models, solution method, and argumentations and evaluations of network planning, scheduling program and observation ability in the corresponding observatory network. The establishment of China EOP monitoring network and maintenance and improvement of COMPASS system will be promoted greatly by means of research results of this project.
