GPS 测姿系统设计与应用

摘要

针对实际测量任务中对运动目标进行姿态测量的使用需求，给出了由天线单元、 GPS 数据测量单元、数据转发单元和中心处理单元构成的 GPS 姿态测量系统总体设计方案。研究了原始数据采集和提取姿态解算方法等关键技术，并给出了系统的总体设计、系统工作流程、计算方程和数据分析结果。在实际环境中对此系统性能和指标进行动态考核，并对试验结果数据进行分析，数据质量完整可靠，验证了系统可行性。%To satisfy the attitude measurement requirement on moving object in actual measurement tasks,a general design scheme for GPS attitude measurement system is given which is composed of antenna unit,GPS data measurement unit,data transfer unit and central processing unit.Then some key technologies are researched,including data collection and extraction,attitude resolving algorithm. The overall design of the system,system work flow and analysis of practical application data are described in detail.The system is tested to check system performance in the real environment,and the feasibility of the system is verified through analysis of the test result data.
