OBC二次定位系统定位算法研究

Study on positioning algorithm of OBC secondary positioning system

本文针对OBC海洋地震勘探二次定位工作中背景噪音干扰大、实时性要求高的特点,在传统最小二乘估计方法的基础上提出了比较法错误剔除、稳健估计和序贯平差的联合数据处理方法,提高了数据质量和工作效率。

In view of the characters of large interference of background noises and high real-time requirement in secondary positioning job of OBC offshore exploration, the paper presented mistake deleting by joint data processing method of comparison test, robust estimation and sequential adjustment on the basis of least square estimation method, improving the data quality and work efficiency.
