The data processing method in single area of Space network and Astro-geodetic network combined adjustment

BEI Jing-zhong①②,CHENG Ying-yan①,CHENG Peng-fei①(①Chinese Academy of Surveying and Mapping,Beijing 100039;②School of Geodesy and Geomatics,Wuhan University,Wuhan 430079)  
The Space network and Astro-geodetic network combined adjustment in China is a huge engineering of data processing,and unknown parameters are much more.For checking gross error of raw observation data and testifying weight matching relations of Space network and Astro-geodetic network,the research and calculation of data processing in single area are needed.The paper mainly discusses the math model,the effective solution method of large scale sparse matrix in data processing of combined adjustment,and develops a combined adjustment software.With 5000 points observation data as experimental data,a useful conclusion can be obtained.
