推进欧盟-亚洲卫星导航产业合作

农业 Agriculture

EGNOS与伽利略卫星导航系统能够帮助农民提高效率,减少化学物的使用,并提高单产。通过提高卫星信号的准确性、覆盖面、可靠性与持续性,EGNOS与伽利略系统将消除在精细农业应用方面的一些障碍。

The use of EGNOS and Galileo satellite navigation systems can help farmers become more efficient, reduce their use of chemicals, and increase crop yields. By increasing the accuracy, availability, reliability and continuity of satellite signals, EGNOS and Galileo will remove some of the barriers to the adoption of precision agriculture.

                    

EGNOS更高的准确度也能够应用于可变比率发生器(VRA)——精细农业中的一项技术。VRA要求GNSS感应器、航空影像以及其他用于确定除草剂和化肥等投入物最佳用量的信息管理工具的运用能够节省农民的开支、减少投入物对环境的影响、并提高作物单产。通过VRA的应用,农民根据田地里观测到的差异调整投入物用量。例如,只在一块农田长了杂草的部分施用除草剂。

The improved accuracy of EGNOS can also be used by farmers for what is called Variable Rate Application (VRA), a practice used in precision farming. VRA requires the use of GNSS sensors, aerial images, and other information management tools for determining optimum herbicide doses, fertiliser requirements and other inputs to help farmers save money, reduce their impact on the environment and increase crop yields. With VRA farmers adjust their doses in field operations to the observed variability in the field. For example, only sections of a field with weeds are treated with a herbicide.

FieldFact(http://www.fieldfact.com/Home/tabid/562/Default.aspx)是欧盟第七框架计划(FP7)的一个项目,其进行的应用研究发现,EGNOS与伽利略系统能够用于精细农业的以下一些方面:

  • 拖拉机与农机引导
  • 机械化除草
  • 奶牛繁殖力检测
  • 虚拟栅栏
  • 地块识别和地理追踪
  • 收获后拾遗
  • 有监督的农畜追踪
  • 农田测量
  • 农田边界绘图与更新

因此GNSS,尤其是EGNOS与伽利略系统,对于农业领域的诸多应用都显然会是十分有益的。

FieldFact (http://www.fieldfact.com/Home/tabid/562/Default.aspx), an FP7 project established to promote the use of EGNOS and Galileo in the agricultural sector, has found that EGNOS and Galileo can be used in precision farming for among other applications:

  • Tractor guidance and implement guidance
  • Variable ploughing, seeding and spraying
  • Mechanical weeding
  • Cow fertility detection
  • Virtual fencing
  • Land parcel identification and geo-traceability
  • Post harvest pick-up
  • Supervised tracking of livestock
  • Field measurements
  • Field boundary mapping and updating

It is thus clear that the use of GNSS and in particular Galileo and EGNOS can be very beneficial for a plethora of applications in agriculture.
