基于GNSS互操作的农用车辆自主运行技术仿真研究

摘要

一方面以信息高科技为基础的集约化农业问世的“精确农业”，已经成为农业可持续发展研究的热门领域；另一方面GPS原有的垄断地位已经逐渐由GNSS所取代。因此，基于GNSS互操作的农用机车自主运行研究成为了“精确农业”当中新的研究课题。本文提出了以GNSS互操作为基础的农用车辆导航技术的概念，设计了相应的系统组成结构，并对各个组成结构的原理、功能进行了逐一论述。通过仿真验证表明GNSS互操作为基础的农用车辆自主运行技术比以GPS为基础的原有技术具有更高的精度。%On one hand, the advent of intensive agriculture based on the information hi-tech "precision agriculture" has become a hot area of the sustainable development of agriculture; On the other hand, the original monopoly position of GPS has been gradually replaced by GNSS. Therefore, the autonomous operation of the agricultural locomotive based on GNSS interoperabili- ty has become a new research topic in the area of precision agriculture. The paper proposed the concept of agricultural vehicle navigation technology based on GNSS interoperability; designed the structure and composition of the accordant system;dis- cussed their functions respectively. The simulation results show that the autonomous operation based on GNSS interoperability has a higher accuracy than the original GPS based technology.
