Real-time coseismic wave retrieving by integrated Kalman filter with observations of GPS,Glonass and strong-motion sensor

A method of real-time coseismic wave retrieving was proposed based on the tight integration of GPS, Glonass and strong-motion sensor observations, the validation and precision analysis have been made by an experimental data. The series of results have been shown that: by the integrated Kalman filter and multi-sensors, the coseismic waves can be optimally recovered by complement the advantages of each other, especially when the observation conditions are very bad. In additional, the results are not significantly effected by different receiver clock error processes for the integration solution.     

区域性无源三维导航定位系统研究

在总结国外区域导航的新进展后，以Ｌｏｏｐｕｓ为基础，对Ｌｏｏｐｕｓ的卫星运动轨道作了进一步阐述。结合我国国情，提出五种区域导航星座设想，其中含区域导航和通信相结合的建议、方案。最后，对比ＧＰＳ方案之后，认为Ｌｏｏｐｕｓ方案是我国应采取的方案，并就此提出４项攻关技术
