- In order to get this , some useful explorations on how to analysis and solve the problem of the ill - conditioning have been made and several biased estimators have been put forward . in fact , analyzing the essence , overcoming the effect of ill - conditioning and obtaining more accurate and stable parameters estimator is an new task in gps surveying data processing , which have been determined as an important studying field in contemporary surveying error theory and engineering data processing by the international association of geodesy ( iag )
事实上，分析测量平差系统病态性的实质、克服或减弱测量平差系统病态性的影响、采用有偏估计等方法提高参数估计和平差成果的精度，是当前gps等重大测量工程数据处理中所面临的一个重要课题，它已被国际大地测量协会( iag )确立为现代测量误差理论及数据处理研究中的一项重要内容。 - How to analyze the essence , overcome the effect of ill conditioning and obtain more accurate and stable estimation of the unknown parameters are very important in many fields , such as gps surveying data processing , and have been determined as an important studying field in contemporary surveying error theory and engineering data processing by the international association of geodesy ( 1ag ) . the dissertation begins with review of the main history of ill conditioning research
如何针对测量实际，分析测量平差系统病态性的实质、克服或减弱测量平差系统病态性的影响、取得更为准确的参数估值和可靠的平差成果，是当前gps等重大测量工程数据处理中所面临的一个重要课题，它已被国际大地测量协会( iag )确立为现代测量误差理论及数据处理研究中的一项重要内容。
