Due to the influence of variations in landform,geophysical data acquisition is usually subsampled. Reconstruction of the seismic wavefield from subsampled data is an ill-posed inverse *** sensing(CS) can be used to recover the original geophysical data from the subsampled *** this paper,we consider the wavefield reconstruction p.o.lem as a CS and p.o.ose a piecewise random subsampling scheme based on the wavelet *** p.o.osed sampling scheme overcomes the disadvantages of uncontrolled random sampling. In computation,an l-norm constrained trust region method is developed to solve the CS *** results demonstrate that the p.o.osed sampling technique and the trust region app.o.ch are robust in solving the ill-posed CS p.o.lem and can greatly imp.o.e the quality of wavefield recovery.

第三届中国卫星导航学术年会

作者： Haifu Ji1, 2*, Lihua Ma1, Guoxiang Ai1, Meng wang1, 21 National Astronomical observatories, chinese academy of sciences, Beijing 100012,China2 graduate university of chinese academy of sciences, Beijing 100049, China

In GNSS （Global Navigation Satellite System）, the accuracy of position estimates depends upon the measurement geometry and pseudorange measurement errors. The Dop （Dilution of precision） p.o.ides a simple characterization of the user-satellite geometry. An in-depth study of Dop distribution characteristics is conducted in this paper, with emphasis on performance bounds of HDop （Horizontal Dilution of precision） and VDop （Vertical Dilution of precision） for four satellites in varied hypothetical constellations. The distributions of HDop and VDop in sixteen major world cities are analyzed by simulated calculations using the TLE sets of GpS satellites. According to the theoretical analyses about the distributions of HDop and VDop, this paper also p.o.oses a new algorithm of fast selecting satellites based on HDop and VDop, which requires a shorter computing time than the general method and p.o.ides a feasible way to quickly achieve a high-accuracy positioning.

In the p.o.f-of-concept phase of chinese Area positioning System （CApS）, the user receiver can calculate local altitude and further achieve three-dimensional positioning by pressure sensor which can be used to measure atmospheric pressure and temperature. Additionally, the meteorological parameters, such as atmospheric pressure, temperature and humidity, can be resorted to analyze tropospheric delay from the satellite to the user. In this work, the MS5534C barometer module is applied in CApS. The results show that positioning and navigation with a high performance can be achieved, which can well satisfy the requirements of the common users.
