采用美国国防部星座式全球性卫星定位导航系统和GARMINGPS95型接收机进行飞播造林导航试验，结果表明，采用GPS导航试验，播区平均有效落种率为86．7％，超过了85％的国家标准，飞行作业日减少35％，节省飞播作业导航投工、投资78％．
Adopting the constellation global satellite navigation system and GARMINGPS95 receiver of the U.S. Department of Defense, the airborne broadcast afforestation and navigation test was conducted. The results showed that with the GPS navigation test, the average effective seed coverage rate in the broadcast area was 86.7% and over 85% Standard, flight operations reduced by 35%, saving flight operations navigation investment, investment 78%.
