基于GPS相位法对舰船等大型载体定姿中的模糊数求解方法

摘要

In this paper, GPS was used with baselines in a four-antenna configuration to obtain naval vessel attitude in real time. A new cycle ambiguity search algorithm using data filter method combined with Space Geometry Constraint (SGC) was brought forward to improve attitude determination quality (Success Ratio) and resolving speed on-the-fly (OTF). Experiments results and accuracy analyses were also provided.%本文讨论采用四天线GPS载波相位接收机对舰船等大型载体的定姿方案，提出用数据平滑与空间几何约束相结合的方法来解决快速确定定姿方程中模糊数的难题。提高了定姿成功率，并通过实测数据进行了验证及精度分析。
