摘要
在讨论利用差分技术来降低 GPS数据误差的基础上 ,提出了 GPS数据误差相关性的概念。通过对这种误差相关性的分析 ,讨论在差分过程中利用人工神经网络来减小 GPS数据误差 ,从而建立了 GPS数据差分人工神经网络模型 。
Based on reducing the error of GPS data with difference technology, this article induces the conception of error coherence. According to the analysis of error coherence, we discussed the error reducing of GPS data by artificial neural networks model in the process of difference. Then the artificial neural networks model of GPS data difference is proposed and its feasibility is validated by examinations.
