飞机播种造林是我国造林绿化的重要方式之一,在交通不便、人烟稀少的山区和沙漠地区更具特殊意义。在飞机播种造林中,如何使空、地勤合理配合引导飞机在播区内均匀撒播种子是飞播造林的关键技术之一。利用GPS进行飞播造林导航,可以解决先进高速的空勤与落后缓慢的地勤之间长期存在的矛盾。通过GPS导航与传统人工地面信号导航的对比试验,GPS可以提高飞行作业的安全系数,提高播种质量,节省大量人力、物力,完全可以更替人工地面信号导航方法,具有良好的经济效益和社会效益。
Sowing and planting aircraft is one of the most important ways for afforestation in our country. It is of special significance in mountainous areas and deserts with limited transportation and sparsely populated areas. In aircraft sowing and afforestation, how to make space and ground to cooperate rationally to guide the aircraft to sow seeds evenly in the sowing area is one of the key technologies of aerial seeding and afforestation. The use of GPS for aerial seeding afforestation and navigation can solve the long-standing contradictions between advanced high-speed airborne and backward lagging ground handling. Through the comparative experiment of GPS navigation and traditional artificial ground signal navigation, GPS can improve the safety factor of flying operation, improve the planting quality, save a lot of manpower and material resources, and can completely replace the artificial ground signal navigation method, which has good economic and social benefits.
