基于MEMS/GPS的航向姿态测量系统设计

姿态信息是飞行控制中最关键的参数之一。针对飞行控制系统首要解决的姿态测量问题。本文利用多微机电系统（MEMS）传感器与GPS组合，研制了一种微型航向姿态测量系统。考虑在以往的姿态测量系统中，动加速度的影响限制其应用，通过设计利用GPS进行辅助修正的姿态解算算法，有效规避了运动加速度对测量精度的影响，使系统可同时满足静态情况和动态情况的使用。将试验结果与商用姿态测量产品MTI-G-700的姿态结果进行了比较，各项指标均达到系统设计的性能要求，验证了航向姿测量系统设计的有效性。

Design of Attitude and Heading Reference System Base On MEMS/GPS

Attitude information is one of the most important parameters in flight control.Focus on the most important problem of attitude measurement in flight control system. This paper,a kind of micro attitude attitude and heading reference(AHRS)is developed based on the combination of multiple MEMS sensors and GPS. In the past,the atti?tude measurement system,kinetic acceleration effects limit its application,through design of auxiliary correction al?gorithm based on GPS velocity,effectively avoid the influence of kinetic acceleration on the measurement accuracy. The system can meet the use of static and dynamic situation. The test results are compared with commercial attitude measurement product MTI-G-700 show that,the design of attitude and heading reference system is validity.
