Development and evaluation of a small UAV for low-cost multi-spectral image sensing

在该项目中，研制了一种小型无人机（UAV） gav3，以比有人驾驶飞机和传感卫星更低的成本拍摄农业多光谱遥感图像。还完成了在真实环境下的遥感试飞。GAV-3的总重量约为1.6公斤，在手动发射后通过腹部着陆回收。任务轮廓是100米爬升和徘徊，以拍摄遥感图像。实现了姿态调平和高度保持的自动控制。地面操作员仅指示水平飞行航线以供UAV测量。

In this project, a small unmanned aerial vehicle (UAV) GAV-3 has developed to take agricultural multi-spectral sensing images with lower-cost than manned aircrafts and sensing satellites. A test flight for remote sensing in the real environment was also accomplished. The all-up weight of GAV-3 is approximately 1.6 kilogram and it is recovered by belly landing after hand launch. The mission profile is 100 meter climb and loitering for taking sensing images. Automatic control for attitude leveling and altitude holding has been implemented. A ground operator only indicates the horizontal flight course for survey to the UAV.
