    • A system for determining the position and/or velocity of an autonomous aircraft in a low-cost, low-weight manner independent of external technological dependencies such as satellites or beacons is claimed. The solution comprises a combination of traditional technologies (IMUs, altitude sensing, control systems, visual sensing technology, etc.) coupled with algorithms to implement their combined use. The solution is small enough for inclusion on small mass aircraft, yet its precision and capability make it useful for large aircraft as well. Utilizing the positional data, a series of control loops is claimed which allow an aircraft to autonomously take-off and land, station hold in a very precise manner, and fly in very close proximity to other objects with little chance of collision.
    • 声称用独立于诸如卫星或信标之类的外部技术依赖的低成本,低重量方式确定自主飞行器的位置和/或速度的系统。 该解决方案包括传统技术(IMU,高度感测,控制系统,视觉感测技术等)的组合,以及实现其组合使用的算法。 该解决方案足够小以包含在小型飞机上,但其精度和能力也使其对大型飞机有用。 利用位置数据,要求一系列控制回路,其允许飞机以非常精确的方式自主地起飞和着陆,驻车,并以非常接近其他物体的飞行,几乎没有碰撞的机会。
