利用GPS校准、带温度补偿的无人机气压高度测量

The method to measure the barometric height for UAV ( Unmanned Aerial Vehicle) is proposed, in which the barometric height is calibrated by GPS ( Global Position System) height and is compensated by atmosphere temperature.

针对某型民用摄像无人机的高度测量问题，提出了利用GPS校准、带温度补偿的气压高度测量方法。

The calibration system of sensor is designed and realized. Sensors in the unmanned aerial vehicle system such as attitude angle sensor, barometric height sensor and airspeed sensor are calibrated times without number. Each of their stationary models is deduced.

设计实现了传感器标定建模，以无人机系统中倾角传感器、气压高度传感器和空速传感器等为例，进行了传感器数据的标定拟和，得到了各传感器的静态模型。

The method introduced here makes the barometric height as close to real height as possible with resolution high to 12m and satisfies the requirements of UAV height measurement for remote sensing and flight control.

本方法使所测得的气压高度尽可能地接近真实高度，所设计的高度测量通道分辨率达到12米，满足了无人机遥测和飞行控制对高度测量的要求。

The techniques of the barometric height measurement are researched, which is calibrated by GPS information and compensated by temperature information. The barometric height measurement channel of high resolution is designed with the help of curve-fitting and digital filtering algorithm.

研究了利用GPS校准零点、带温度补偿的气压高度测量技术，通过曲线拟合与数字滤波技术，设计了具有较高分辨率的气压高度测量通道。

A barometric altimeter indicates height above sea level or some other selected elevation.

气压高度表用以指示海平面或另外某个被选定高度以上的高度.
