基于GNSS载体的姿态测量系统设计
系统GPS接收模块选择ublox公司的NEO-6T 芯片，微处理器模块选择ST公司的STM32F103RCT6单片机，再与其他的一些硬件一起组成了硬件平台，然后在Keil MDK编译环境上编写程序。系统所需实现的功能主要为接受原始的GPS信息，进行坐标变换，数据处理，最后解算出载体的姿态角，实现对载体的姿态测量。
本文还通过实验对系统的功能做了具体的评估，验证了系统的可行性。根据实际研究情况对本课题进行总结，对今后工作提出展望。

Title Design of GNSS-based carrier attitude measurement system
Abstract
With the rapid development of information technology,IT has penetrated into both military and civilian fields.In the field of vehicle, aircraft and ship,attitude parameter is one of the important navigation parameters, and attitude measurement has gradually become the focus of vector navigation.In this paper, the design of a dual antenna attitude measurement system based on GPS is studied.
The GPS receiver module selects the NEO-6T chip of ublox, and the microprocessor module selects the STM32F103RCT6 microcontroller of ST.And then together with some other hardware to form a hardware platform, and then in the MDK Keil compiler environment to write the program.The function of the system is mainly to receive the original GPS information, coordinate transformation, data processing, and finally solve the attitude angle of the carrier, and realize the pose measurement of the carrier.
In this paper, the function of the system is evaluated, and the feasibility of the system is verified.. According to the actual situation of the research, this paper will sum up the future work and put forward the prospect of the future.
