中国大地测量数据处理60年重要进展 第二部分:大地测量参数估计理论与方法的主要进展

Progress of Geodetic Data Processing for 60 Years in China Part 2:Progress of Parameter Estimation Theory and Methodology

大地测量参数估计原理是大地测量数据处理的重要基础。中国学者经过60年不懈努力,在自由网平差、拟稳平差、半参数估计、不适定问题解算方法、抗差估计、自适应滤波等领域做出了重要贡献,建立了许多新的理论、模型和方法,推进了大地测量数据处理理论的进展。这一部分重点介绍建国60年来中国学者在大地测量数据处理原理、方法方面取得的成就。

The theory and methodology of the parameter estimation are the fundamental of data processing. By continuous working for 60 years, the Chinese geodesists have developed the quasi-stable adjustment principle, robust estimation based on equivalent weight principle, robust estimation for correlated observations, adaptively robust filters etc. The free net adjustment methodologies, semi-parameter estimation, estimation for ill-posed problems have also been researched in detail. Some new theories and methodologies have been established which promote the geodetic data processing. In this paper, the emphases are on the progresses of the parameter estimation principles contributed by Chinese geodesists.
