基于Sigma-Epsilon模型的多路径改正
首发时间:2011-08-25
摘要:多路径效应是GPS测量中主要的误差源之一,其严重损害GPS的测量精度。在介绍了多路径效应产生的原理、作用特性,以及国内外处理多路径误差的技术后,重点采用Sigma-Epsilon模型来改正多路径误差。通过对实验数据的计算,验证了程序的可行性,并达到了对多路径误差改正的目的。

The Multipath Correction Based on the Sigma-Epsilon Model
Abstract:Multipath effects is one of the major sources of errors in GPS measurements, and it is serious damage to the GPS accuracy. After the introduction of the principle of multi-path effect occurs, the role of features, and multipath error handing domestic and foreign technology, focusing on the use of Sigma-Epsilon model to correct multipath errors. Calculated by the experimental data to verify the feasibility of the program, and meets the multipath error correction purposes.
