本发明公开了一种通航飞机及小型飞行器航姿的测量方法包括数据采集单元、数据处理单元和数据校准单元;数据处理单元是由单片机及其外围电路组成,数据校准单元是单片机的内部代码,包括以下步骤:S1,数据采集:三轴的加速度传感器分别对纵向加速度、垂直加速度和横向加速度的数据采集;三轴的陀螺仪分别对俯仰率、滚转率和偏航率的数据采集;三轴的加速度传感器和三轴的陀螺仪的侧部均固定设置有温度传感器;S2,数据处理;S3,数据校准补偿:数据校准单元先对数据处理后的数据进行筛选,再对三轴的加速度传感器和三轴的陀螺仪的测量值进行温度补偿,然后进行数据校准补偿;数据校准补偿分为传感器校准、类型校准和特定校准。

    The invention discloses a method for measuring the heading attitude of a general aviation aircraft and a small aircraft. A data acquisition unit, a data processing unit and a data calibration unit are included; the data processing unit is composed of a single-chip microcomputer and a peripheral circuit thereof, the data calibration unit is an internal code of the single-chip microcomputer. The method comprises the following steps: S1, data acquisition: a three-axis acceleration sensor respectively acquires data of longitudinal acceleration, vertical acceleration and transverse acceleration; wherein the three-axis gyroscope is used for collecting data of the pitch rate, the rolling rate and the yaw rate. and temperature sensors are fixedly arranged on the side parts of the three-axis acceleration sensor and the three-axis gyroscope; S2, data processing; S3, data calibration compensation: the data calibration unit firstly screens the data after data processing, then performs temperature compensation on measured values of a three-axis acceleration sensor and a three-axis gyroscope, and then performs data calibration compensation, wherein data calibration compensation is divided into sensor calibration, type calibration and specific calibration.
