摘要
载体姿态的精确测量是航空和航天、航海的关键技术之一,在军事和民用等方面的作用日益重要。基于GNSS的姿态测量系统具有体积小、成本低以及误差不累积等诸多优点,对于轮船等大型低速度运动载体的姿态确定具有很好的应用价值。本文基于GNSS载波相位观测量,以Turbo C++为平台设计了实时测姿系统,并编写了实时测姿软件。最后将该测姿系统应用于某型测量船上,利用船上记录的原始接收机二进制记录文件,模拟实时进行处理;并与船上惯导输出值相比对验证了测姿系统的有效性及精度。针对船上多路径大的特点,给出了一些数据处理经验。试验结果表明,设计实现的GNSS测姿系统,其航向测姿精度为40″;纵摇及横摇测姿精度分别为130″和100″。
The accurate determination of the attitude of carrier was becoming important in the civil and military fields, which was one of the key technologies in the aviation, aerospace and marine. GNSS-based attitude determination system with small size, low cost, and the error was not cumulative. It was very suitable for ships and other large-scale low-speed moving vehicle attitude determination application. Based on GNSS carrier phase measurements, this paper designed a real-time attitude determination system, authoring a real-time attitude determination software on Turbo C＋＋ platform. Finally, this attitude determination system was applied on a survey ship, using the onboard recording of the original receiver binary log file to simulate a real-time processing to verify the validity and accuracy of the attitude determination system with the output of INS. Due to the large multipath noise of ship, some data processing experience was given. The designed attitude determination system heading attitude accuracy was 40 ″, pitch and roll attitude determination accuracy were 130″ and 100 ″.
